The gusset plate is subjected to the forces of three members. determine the tension force in member c and its angle, , for equilibrium. the forces are concurrent at point o. take f = 8 kn.

The deflecting electric field is 9.50 x 10^14 mv/m.

The force on the drop of ink due to vertical acceleration = ma

And the force on the drop due to electrodes = qE

To calculate the deflecting electric field, we need to equate both these forces,

Hence, qE = ma

As there are 751896 extra electrons, the charge due to them will be = 751896 x 1.6 x 10^-19

M = mass of each drop of ink = 11 kg

A = acceleration of the drop of ink = 104 m/s^2

Putting the above values in the equation, qE = ma

1.6 x 10^-19 x 751896 x E = 11 x 104

On solving the above equation

E = 9.50 x 10^14 mv/m

Hence, the deflecting electric field is 9.50 x 10^14 mv/m.

The distance travelled by the car in the first 20 seconds of the motion is 130 m.

The area under the speed-time graph is the distance the particle travels.

The distance traveled by the car in the first 20 seconds is calculated as follows;

From the speed - time graph, at 20 seconds, the speed of the car is 13 m/s.

Distance = area of the graph = area of triangle formed from time, 0 s to 20 seconds.

Distance = ¹/₂bh

Displacement is the movement of unfavorable emotions from one thing or person to another.

As a kind of self-preservation, displacement is the act of shifting one's unfavorable emotions from one thing or person to another.

According to the notion, releasing stress or worry on a non-threatening target helps a person deal with negative emotions like fear or rage.

For instance, if a person feels angry because their boss yells at them, they might project those feelings onto someone or something else, such a member of their family or a piece of furniture.

For fear of losing their work, the person could feel unable to face their manager. As a result, they might vent their rage on a less dangerous person like their partner or housemate.

An object experiences a push or pull as a result of interacting with another object. Each object is subject to a force whenever two objects interact. The two items no longer feel the force after the interaction ends.

In physics, a force is an effect with the capacity to change the velocity of an object. A force can cause an object with mass to move at a different speed or accelerate. To describe force, a push or a pull makes intuitive sense. Forces have both magnitude and direction because they are vector quantities.

Answer:

H1 = V t1 - 1/2 g t1^2      where upward is chosen as positive

H2 = -V t2 - 1/2 g t2^1     second stone thrown downwards

V t1 - 1/2 g t1^2 = -V t2 - 1/2 g t2^2

V (t1 + t2) = 1/2 g (t1^2 - t2^2)

V = 1/2 g (t1 - t2)

t2 = 2 V / g = 96 / 9.8 = 9.8 sec

Check:

One can also note the stone 1 will return to the starting point with a time delay of V / g * 2 which is 96 / 9.8 = 9.8 sec because the time for stone 1 to go to zero is 48 / 9.80 = 4.90 sec when its velocity reaches zero

Approximately 9.8 seconds when rounded to one decimal place. Therefore option F is correct.

Calculate the time it takes for the first stone to hit the street (t1) and the time it takes for the second stone to hit the street (t2).

For the first stone (thrown straight down):

Using the equation of motion:

[tex]\rm \[ d = \frac{1}{2} g t_1^2 \][/tex]

where:

d = distance traveled (height of the building)

g = acceleration due to gravity = [tex]\rm 9.8\ m/s^2[/tex] (downward)

Since the stone is thrown from the top of the building, the distance traveled (d) is equal to the height of the building.

Now, let's find t1:

[tex]\[ h = \frac{1}{2} g t_1^2 \]\\\ \\t_1^2 = \frac{2h}{g} \]\\\\\ t_1 = \sqrt{\frac{2h}{g}} \][/tex]

For the second stone (thrown straight up):

The initial velocity of the second stone is also 48.0 m/s, but it is directed upward. We can use the equation of motion for upward motion:

[tex]\rm \[ v = u - gt_2 \][/tex]

where:

v = final velocity = 0 m/s (at the peak of the motion, the velocity becomes 0)

u = initial velocity = 48.0 m/s (upward)

g = acceleration due to gravity = 9.8 [tex]\rm m/s^2[/tex] (downward)

Now, let's find t2:

[tex]\[ 0 = 48.0 - 9.8t_2 \]\\\\\ t_2 = \frac{48.0}{9.8} \]\\\\\ t_2 = 4.898 \][/tex]

Since the second stone takes time [tex]t_2[/tex] to reach the peak and another time [tex]t_2[/tex] to fall back down, the total time before the second stone hits the street is [tex]\( 2 \times 4.898 \)[/tex].

[tex]\[ t_{\text{total}} = 2 \times 4.898 \]\\\ t_{\text{total}} = 9.796 \][/tex]

The correct answer is approximately 9.8 seconds (F) when rounded to one decimal place.

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is traveling along a path.

Where:

Where:

t: is that the time = 4.0 s

Hence, the acceleration is:

Explanation:

The number of grams of carbon that combine with 16 g of oxygen in the formation of CO₂ is 6g.

When two elements combine to make more than one compound, the masses of one element combined with a fixed amount of another element are in the ratio of whole numbers, according to the law of multiple proportions.

When combined with oxygen, carbon can produce two different compounds. They are referred to as carbon dioxide (CO₂) and carbon monoxide (CO).

Carbon monoxide is formed by combining 12 g of carbon with 16 g of oxygen whereas Carbon dioxide is formed when 12 g of carbon reacts with 32 g of oxygen. The amount of carbon is fixed at 12 g in each case. The mass ratio of carbon monoxide to carbon dioxide is 16: 32, or 1: 2.

But in the given case, 16g of oxygen is reacting instead of 32g. Therefore, the number of grams of carbon reacting will be:

For reaching the same final velocity as the first attempt by applying a force that is twice as large as the first attempt the time interval should be kept shorter than the first attempt.

After the hockey puck has reached the final velocity and suddenly stops, the hockey puck reduces its speed abruptly.

These solutions can be explained by Newton's Second Law of Motion. According to Newton's Second Law of Motion, the force applied to a particle is directly proportional to the product of the mass and acceleration of that particle.

F = ma; where m is the mass of the particle and a is the acceleration.

Also, a = v/t; where v is the velocity of the particle and t is the time interval.

Therefore, the force applied is inversely proportional to the time interval.

F = mv/t

So, to maintain the same velocity keeping the force at double the time interval should be halved.

Therefore, for reaching the same final velocity as the first attempt by applying a force that is twice as large as the first attempt the time interval should be kept shorter than the first attempt.

Acceleration is the rate of change of the velocity of an object with respect to time. Its unit is m/s² and can be given as,

a = dv/dt

Where , dv and dt is the small change in velocity and time of an object.

Velocity of an object can be said as, the rate of change of displacement with respect to time of an object . Its unit is m/s and it is a vector quantity.

V = Δx/Δt

In here , V is velocity ,  Δx is change in displacement and Δt is change in time of an object.

We are know that ,

Initial velocity of the car = u = 15 m/s

Final velocity  of the car = v = 28 m/s

Covered time of the car = t = 5.8 s

Therefore we know the equation of motion can be given as,

v = u + at

Hence , to get the acceleration of the car we may put the values in above equation then,

28 m/s = 15 m/s + (5.3) a

a = (28 m/s - 15 m/s) /5.3s

a = 2.45 m/s²
