Answer:
As described, The mantle causes the tectonic plates to move.
Answer: d. 5 m/s^2
Explanation:
Acceleration is the change in velocity in a given time.
a = (30-20)/2 = 5
There is half the force that there was before it was split in half
Answer:
When he weight of the car is 8.55 x
N then power = 314.012 KW
When he weight of the car is 1.10 x
N then power = 43.76 KW
Explanation:
Given that
Initial velocity
= 0
Final velocity
= 24.8 
Time = 7.88 sec
We know that power required to accelerate the car is given by
P = 
Change in kinetic energy Δ K.E = 
Since Initial velocity
= 0
⇒ Δ K.E = 
⇒ Power P = 
⇒ Power P =
-------- (1)
(a). The weight of the car is 8.55 x
N = 8550 N
Put all the values in above formula
So power P = 
P = 314.012 KW
(b). The weight of the car is 1.10 x
N = 11000 N
Put all the values in equation (1) we get
P = 
P = 43.76 KW
