B) They are all sources of electricity
Hope it helps!!
The acceleration of the car is stated as -2 m/s², while the deceleration of the car is termed as 2 m/s².
Answer:
Explanation:
Acceleration exerted by any object in order of decrease in the speed is termed as deceleration. In other words , negative acceleration or acceleration acting in opposite direction to stop the motion of any object is termed as deceleration. The magnitude of acceleration and deceleration is same only the direction is completely opposite to each other. So the negative sign will be obtained for acceleration value of any object whose velocity slows down from initial velocity.
Here , the initial velocity was 60 m/s and the final velocity is slowed down to 40 m/s in time 10 s.
So acceleration = (Final velocity - Initial velocty)/Time
Acceleration = (40-60)/10 = -20/10 = -2 m/s².
Thus, the acceleration of the car is stated as -2 m/s², while the deceleration of the car is termed as 2 m/s².
We don't know. A black hole is a star that has collapsed into its own gravity. The gravity in fact, is so strong that even light cannot get through it. That's why it looks black to us.
<span>when a wave causes vibration in a nearby object that matches the frequency of the wave, the phenomenon that occurs is called resonance.
It produces a sound of larger amplitude as a result of vigorous vibration of the body.

Hello There!
If i remember correctly, it is tension force.
Hope This Helps You!
Good Luck :)
