The tension in the string between the blocks depends on the applied force F and the ratio of the masses mB/mA.

When the frictionless system is accelerated by an applied force of magnitude F, the tension in the string between the blocks can be determined using Newton's Second Law of Motion. The equation for this law is F = m*a, where F is the force, m is the mass, and a is the acceleration.
For the block connected to the applied force, let's call it block A, the force equation would be F = mA*aA. For the other block, block B, the force equation would be T = mB*aB, where T is the tension in the string. Since both blocks are connected by the string and moving together, their acceleration (aA and aB) is the same.
We can now express the tension T in terms of the applied force F, masses mA and mB, and the acceleration a:
T = mB*(F/mA).

Answer:

Gram and Kilogram are the units mass is represented in

Explanation:

The part b, where the current is decreasing, will be at the higher potential.

An electrical conductor experiences an electromotive force (emf) when it is passed through by a magnetic field that is changing, which is known as electromagnetic or magnetic induction.

Lenz's law of electromagnetic induction states that the magnetic flux in the coil changes as a result of the relative motion between the coil and the magnet, and the induced EMF is always directed in a way that opposes the flux change.

So, the increase in current will cause a change in magnetic flux and as a result will lead to the decrease in the induced emf produced and vice versa.

So, the part b, where the current is decreasing, will be at the higher potential.

The quantity that is constant for all planets orbiting the Sun, assuming circular orbits, is the ratio of the orbital period squared (T^2) to the orbital radius cubed (R^3). This relation is known as Kepler's Third Law or the Law of Harmonies.

Kepler's Third Law states that the square of the orbital period of a planet is directly proportional to the cube of its average distance from the Sun. Mathematically, it can be expressed as:

T^2/R^3 = constant

To derive this relation, let's start with the basic equation for centripetal force:

F = (m*v^2) / R

where m is the mass of the planet, v is its orbital velocity, and R is the orbital radius.

The centripetal force is also given by the gravitational force between the planet and the Sun:

F = (G * M * m) / R^2

where G is the gravitational constant and M is the mass of the Sun.

Setting these two expressions for F equal to each other and rearranging, we have:

(m*v^2) / R = (G * M * m) / R^2

Canceling the mass of the planet (m) from both sides, we get:

v^2 / R = (G * M) / R^2

Rearranging the equation further, we have:

v^2 = (G * M) / R

We know that the orbital velocity of a planet is given by:

v = 2πR / T

Substituting this expression into the equation, we have:

(2πR / T)^2 = (G * M) / R

Simplifying, we get:

4π^2 * R^2 / T^2 = (G * M) / R

Multiplying both sides by T^2 and dividing by 4π^2, we obtain:

R^3 / T^2 = (G * M) / (4π^2)

Since (G * M) / (4π^2) is a constant, we can rewrite the equation as:

R^3 / T^2 = constant

Therefore, the correct answer is (b) T^2 R^3.

a) To calculate the initial thermal energy of each substance, we can use the formula:

Thermal energy = mass * specific heat capacity * temperature

For helium:

Initial thermal energy of helium = 2.0 g * specific heat capacity of helium * 300 K

For oxygen:

Initial thermal energy of oxygen = 8.0 g * specific heat capacity of oxygen * 600 K

The specific heat capacities of helium and oxygen can be found in reference materials or tables.

b) The final thermal energy of each substance can be determined using the principle of energy conservation. Assuming there is no heat transfer to the surroundings, the total initial thermal energy of the system is equal to the total final thermal energy of the system. Therefore, the final thermal energy of helium and oxygen would be the same as their initial thermal energy values calculated in part (a).

c) To determine the amount of heat transferred and its direction, we need to consider the specific heat capacities and the temperature change. The heat transfer can be calculated using the formula:

Heat transfer = mass * specific heat capacity * temperature change

Since the final and initial thermal energies are the same for each substance, we can conclude that no heat is transferred between helium and oxygen.

d) To calculate the final temperature of the mixture, we can use the principle of energy conservation, which states that the total thermal energy of the system remains constant. Assuming no heat is lost to the surroundings, the sum of the final thermal energies of helium and oxygen is equal to their initial thermal energies. By rearranging the equation and solving for the final temperature, we can find the value.

The portion of a horseshoe nail that is folded over flat against the hoof wall to hold the shoe securely to the hoof is called the "clinches". Clinches are the sharp ends of the horseshoe nail that protrude through the hoof wall and are then bent over and flattened against the hoof to secure the shoe in place. The process of bending the clinches is known as "clinching" and is typically done by a farrier, who is trained in proper hoof care and shoeing techniques. Proper clinching is important for maintaining the stability of the horseshoe on the hoof and preventing it from becoming loose or dislodged. It is also important for the overall health and well-being of the horse, as poorly clinched nails can cause discomfort or even injury to the hoof.
The part of a horseshoe nail that is folded over flat against the hoof wall to hold the shoe securely to the hoof is called the "clinch" or "clinch nail." The clinch is an essential component of horseshoeing as it ensures the shoe remains tightly in place, providing stability and protection for the horse's hoof.

Here's a step-by-step explanation of the process:

1. First, the farrier trims and prepares the horse's hoof for the shoe.
2. Next, the appropriate horseshoe size is selected, and any necessary adjustments are made to ensure a proper fit.
3. The farrier then positions the horseshoe on the hoof and drives the nails through the shoe's holes and into the hoof wall.
4. The nails are angled in a way that they come out of the hoof wall without penetrating the sensitive inner structures.
5. Once the nails are securely in place, the farrier cuts off any excess nail length.
6. Lastly, the farrier bends the remaining nail tip over flat against the hoof wall, creating the "clinch." This secures the shoe firmly to the hoof.

The potential difference Vab in the given circuit, with a 19V battery and the rest unchanged, will also be 19V.

In this circuit, if the EMF of the 4V battery is increased to 19V while the rest of the circuit remains the same, the potential difference Vab will be equal to the EMF of the battery. This is because, in a simple series circuit, the potential difference across the terminals of a battery is equal to its EMF.

As the battery EMF is increased to 19V, the potential difference Vab will also be 19V. The voltage is divided across the resistors in the circuit, but the sum of the voltage drops across the resistors will equal the total potential difference, which is the EMF of the battery, in this case, 19V.

The drag (force of air resistance) on the system (man plus parachute) when the skydiver reaches terminal speed is equal to the gravitational force acting on him, which is 80 kg × 9.8 m/s² = 784 N.

To calculate the drag force at terminal speed, we must first understand that at terminal speed, the net force acting on the system is zero. This is because the gravitational force (weight) acting downward on the skydiver is balanced by the upward air resistance (drag force).

The weight of the skydiver can be calculated by multiplying his mass (80 kg) by the acceleration due to gravity (9.8 m/s²), resulting in a gravitational force of 784 N. Since the net force is zero, the drag force must also be 784 N, meaning the force of air resistance on the system at terminal speed is 784 N.

Saturn's moons could have a lot of ammonia and methane ice because the greater cold at Saturn's distance from the Sun means that ices of ammonia and methane could condense there but not at Jupiter.

This makes option C the correct one. The temperatures of the moons of Saturn and Jupiter have significant differences due to their distances from the sun. Saturn is farther away from the sun, which implies it is colder than Jupiter.

The temperatures on Jupiter's moons are mostly too high to condense ices of ammonia and methane, unlike Saturn's moons.  The moons of Saturn's high-speed winds and the lower average density of Saturn’s rings are critical factors contributing to the ammonia and methane ice.

Therefore, it is reasonable to assume that the moons of Saturn have more amounts of ammonia and methane ice as compared to Jupiter.

Hence, it is evident that the moons of Saturn may have large amounts of ammonia and methane ice, while those of Jupiter do not because the greater cold at Saturn's distance from the Sun means that ices of ammonia and methane could condense there but not at Jupiter.

To determine the values of the reactance of the inductor in an L-R-C series circuit, we can use the given information.

The voltage across the capacitor is given as 363 V, and the voltage amplitude of the source is 115 V. This indicates that the voltage across the inductor is the difference between these two values:

Voltage across inductor = Voltage amplitude of the source - Voltage across capacitor

Voltage across inductor = 115 V - 363 V

Voltage across inductor = -248 V

Now we can calculate the reactance of the inductor using Ohm's law:

Reactance of inductor = Voltage across inductor / Current

Reactance of inductor = -248 V / Current

Since the reactance of an inductor is given by XL = ωL, we can rewrite the equation as:

XL = -248 V / Current = ωL

From the given information, we know that the reactance of the capacitor is 488 Ω. In an L-R-C series circuit, the total impedance is given by:

Z = √(R² + (XL - XC)²)

Since the impedance is determined by the sum of resistive and reactive components, we can substitute the known values and solve for the reactance of the inductor:

Z = √(85.0 Ω² + (XL - 488 Ω)²)

Z = √(7225 + (XL - 488)²)

Now we can solve for XL by setting Z equal to the voltage amplitude of the source:

115 V = √(7225 + (XL - 488)²)

Squaring both sides and rearranging the equation, we get:

115² = 7225 + (XL - 488)²

13225 = 7225 + (XL - 488)²

(XL - 488)² = 13225 - 7225

(XL - 488)² = 6000

XL - 488 = ±√6000

XL = 488 ± √6000

Simplifying the expression, we get two possible values for the reactance of the inductor:

XL = 488 + √6000

XL = 488 - √6000

To determine which of these values has an angular frequency less than the resonance angular frequency, we need additional information about the resonant frequency or the value of the inductor. Without that information, we cannot determine which of the two values satisfies the condition.

Assuming that Gilles' weight w is located at a distance l1 from the pivot, the torque τ about the pivot due to his weight can be calculated as:

τ = l1*w

where τ is the torque in units of force times length (e.g. N*m), l1 is the distance between the pivot and the weight in units of length (e.g. meters), and w is the weight of the object in units of force (e.g. Newtons).

So, the expression for the torque τ about the pivot due to Gilles' weight w on the seesaw is simply:

τ = l1*w

In this equation, both l1 and w have units associated with them. The distance l1 is measured in units of length (e.g., meters), and the weight w is measured in units of force (e.g., Newtons). When the equation is multiplied, the resulting torque will have units of force times length (e.g., N*m).

The torque τ represents the rotational force exerted by the weight around the pivot point. It depends on both the distance between the pivot and the weight (l1) and the magnitude of the weight (w). The longer the distance or the greater the weight, the larger the torque will be.

The width of the smaller wall is 8 feet, which is the height of the room's ceiling.

b) The area of the smaller wall can be calculated by multiplying the length and width:

Area = length * width

Area = 14 feet * 8 feet

Area = 112 square feet

c) The larger wall is the one with dimensions 20 feet by 8 feet.

The area of the larger wall can be calculated the same way as before:

Area = length * width

Area = 20 feet * 8 feet

Area = 160 square feet

d) To find the total area of the four walls, we need to sum the areas of the smaller and larger walls:

Total area = 2 * (Area of smaller wall) + 2 * (Area of larger wall)

Total area = 2 * 112 square feet + 2 * 160 square feet

To calculate the final angular velocity of the two skaters, we can use the principle of conservation of angular momentum. The formula for angular momentum is given by L = Iω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.

Initial speed of each skater (v) = 1.60 m/s

Mass of each skater (m) = 70.0 kg

Distance from their locked hands to their centers of mass (r) = 0.690 m

The moment of inertia of a point mass at a given radius is given by I = mr^2.

Since the skaters are initially at rest and have no initial angular momentum, the total initial angular momentum is zero.

To calculate the final angular momentum, we need to find the moment of inertia of the two skaters together. Since they are treated as point masses at the given radius, we can add their individual moments of inertia.

I_total = I1 + I2 = (m1 * r^2) + (m2 * r^2) = (70.0 kg * 0.690 m^2) + (70.0 kg * 0.690 m^2) = 96.39 kg·m^2
