A parallel plate capacitor can store electric charge and
electrical energy, and if the plates are far enough apart,
you can store your lunch in there too.

A distressed car is rolling backward, downhill at 3.0 m/s when its driver finally manages to

konstantin123 [22]

Answer:

Explanation:

Acceleration is equal to the change in velocity over the change in time, or

$a=\frac{v_f-v_i}{t}$ where the change in velocity is final velocity minus initial velocity. Filling in:

$3.0=\frac{v_f-(-3.0)}{6.0}$ Note that I made the backward velocity negative so the forward velocity in our answer will be positive.

Simplifying that gives us:

$3.0=\frac{v_f+3.0}{6.0}$ and then isolating the final velocity, our unknown:

3.0(6.0) = v + 3.0 and

3.0(6.0) - 3.0 = v and

18 - 3.0 = v so

15 m/s = v and because this answer is positive, that means that the car is no longer rolling backwards (which was negative) but is now moving forward.

5. Graph A below plots a race car's speed for 5 seconds. The car's rate of acceleration is 6 m/s^2

Answer:

The answer is below

Explanation:

We are to check if the statement is true of false. If it is false, we correct the statement.

Solution:

Acceleration is the time rate of change of velocity. It is the ratio of the change in velocity to the change in time. The acceleration can be gotten from a velocity time graph by finding the slope of the graph.

The x coordinate represent the time and the y coordinate velocity.

5) Graph A passes through the point (0, 0) and (4, 24). Therefore the acceleration (slope) is:

Acceleration = $\frac{24-0}{4-0}=6\ m/s^2$
