The correct answer is a. 10 km/h.

b. The boat would move at 10 km/h at a 37-degree upstream angle to cross straight (into the current)

To be more precise, the rate of change in an object's position relative to a frame of reference and time is another way to describe velocity. It determines how quickly or slowly something is going. Consider a scenario in which there are two moving items. If both items are going in the same direction, it is simple to determine which one is moving faster than the other.

v = √v_x^2 +v_y^2

v = √((8 km/h)^2 + (6 km/h)^2)

=10 km/h

direction = θ = tan^-1 (opposite / adacrent)

= tan^-1 (6/8)

= tan^-1 (37)

A man is sitting on a chair and exerting 100 N of force downward, while a spring beneath the chair exerts 150 N of force upward. The net force acting on the system is in the upward direction with a magnitude of 50N.

Force is the product of mass and acceleration which is dependent on the rate of change of momentum.

According to the given question,

Magnitude of force in the downward direction = 100N

Downward force = 100N

Magnitude of force in the upward direction = 150N

Upward force = -150N

Net force on the system = Upward force + Downward force

Net force on the system = -150N + 100N

Net force on the system = -50N

Explanation:

The ball that dropped to the ground instead of being thrown will fall first since it only has one force pushing it: gravity.

The other ball has momentum from the horizontal throw so it's fighting against the gravity of the earth to keep going forward. Therefore, the ball dropped instead of thrown is the one that will strike the ground first.

The old kettle with a power rating of 1.4 kW and the new kettle with a power rating of 2.0 kW, due to this the time it takes to boil a fixed volume of water will decrease.

The amount of work finished in a specific length of time is a definition of power. Watt (W), which is derived from joules per second (J/s), is the SI unit of power. Horsepower (hp), which is roughly equivalent to 745.7 watts, is a unit of measurement sometimes used to describe the power of motor vehicles and other devices.

A person's power is always based on the amount of labor they put in, thus if they work differently at different times, their power will likewise vary. Here is when the idea of average power enters the picture.

Hence, as the power will increase, the time will automatically decrease because both are inversely proportional to each other.

The correct answer is d = 312.5 m.

These formulas are used to describe an object's linear motion. Positive acceleration is present if the thing accelerates.

The equations utilised are as follows:

v = u + at

d = ut + 0.5 at^2

v^2 = u^2 + 2 ad

initial velocity u = 25 m/s

acceleration a = - 1 m/s^2

V is equal to zero in the end.

Let d represent the distance covered.

Now, with the third motion equation,

v^2 = u^2 + 2ad

0 = 25^2 - 2 × 1d

d = 312.5 m

The area between the line on the graph and the time axis can be used to calculate the distance travelled.

Explanation:

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom.

This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy. In its core, the sun fuses about 620 million metric tons of hydrogen every second. The PP chain reaction occurs in other stars that are about the size of our sun, and provides them with continuous energy and heat. The temperature for these stars is around 4 million degrees on the Kelvin scale (about 4 million degrees Celsius, 7 million degrees Fahrenheit).

The amount of metal in a closed cylindrical can that is 10 cm high and 4 cm in diameter if the metal on the top and the bottom is 0.1 cm thick and the metal on the sides is 0.05 cm thick is 8.8 cm.

The formula for calculating the volume of a cylinder is given below.

V = πr^2 h

Get the differential of the volume as shown:

dV = V/ h dh + V / r dr

V/ h = πr^2

V/ h  = 2  πr h

Now, the differential becomes

dV =  πr^2dh +  2πrh dr

Given the following parameters

dh = 0.1 + 0.1 = 0.2 cm

dr = 0.05 cm

h = 10 cm

r = 4 cm

Substituting the values in the above equation, we get

dV = 3.14(2)^2(0.2)  + 2(3.14)(2)(10)(0.05)

Answer:Why is important for scientists to write detailed procedures?

Explanation: it lets someone else duplicate your experiment exactly

The static frictional force acting on the block is equal to 90 Newton's.

Friction is a force that acts opposite to the direction of motion of body in order to oppose its motion. Frictional force is of two types -

The Static frictional Force - F[s] = μ[s] N

The Kinetic frictional force - F[k] = μ[k] N

Given in the question is a box of weight 120 N initially resting on a horizontal table. From the data given, we can write -

Weight of box [W] = 120 Newton

Coefficient of static friction (μ[s]) = 0.75

Coefficient of Kinetic friction (μ[k]) = 0.40

Horizontal push (F[h]) = 84 N

We know that -

F[s] = μ[s] N           [Static friction]

F[k] = μ[k] N           [Kinetic friction]

Now, initially the box is at rest so the opposite frictional force will be 0.  When a horizontal force of 84 Newton is applied on it, the static friction will try to oppose the motion. For forward motion of the block -

F[h] = F[s]

F[h] = μ[s]

84 = 0.75 x 120            (Normal Reaction [N]  = Weight)

84 = 90 ≥ 0

- 6 = 0

which is false.

This means that the static frictional force is greater than horizontal push and opposes the motion. The force due to static friction will only exist since, the body was able to move, so kinetic friction is of no use here.

So, the frictional force on the block will be = F[s] =  μ[s] N = 90 Newtons.

Therefore, the static frictional force acting on the block is equal to 90 Newton's.

Light moves. Slower in lens but faster in the air That’s because light refracts when it comes into contact with various materials.
