A car is traveling at 40 m/s. The brakes are applied an after 3 seconds the car is traveling 13 m/s. What is the acceleration of
Elena-2011 [213]

Answer:

- 9m/s²

Explanation:

Given parameters:

Initial velocity  = 40m/s

Time taken  = 3s

Final velocity  = 13m/s

Unknown:

Acceleration of the car  = ?

Solution:

Acceleration is the rate of change of velocity with time taken.

   Acceleration  = \frac{Final velocity  - Initial velocity }{Time taken}  

  Acceleration  = \frac{13  - 40 }{3}   = - 9m/s²

Now, remove the positive charge by dragging it back to the basket, and drag one negative charge toward the middle of the screen.
Bess [88]

The correct option is;

The voltages become negative instead of positive and keep the same magnitudes

Explanation: Here we have that there is a change in direction from positive to negative with the direction pointing to opposite of the initial direction whereby the field strength does not change due to the reversal of the. Therefore the voltage becomes negative instead of negative while keeping the the magnitude.

That is there is a electric field reversal or a change electric field direction.
