Answer:
Ocean-Ocean Convergence
As the subducting plate is pushed deeper into the mantle, it melts. The magma this creates rises and erupts. This forms a line of volcanoes, known as an island arc
Answer:
0.119 s is the correct answer to this question.
Explanation:
As mentioned in the question
U=3.89\ m/s
a=-1.44\ m/s^2
S=4.8\ m
Consider the final speed of the softball covering the distance of 4.8m is v
Now using the equation

Putting the value of U, A, S in the previous equation we get

Now again using the equation
v=U+at
where U=intial velocity, t= time
Substituting the value of v, U, a

Hence the slide time is 0.119 s
Answer:
Height will be equal to 0.4489 m
Explanation:
We have given mass of the toy m = 0.50 kg
Initial kinetic energy K = 2.2 J
We have to fond the height of the hill over which car roast
When car will roast the hill its kinetic energy will be converted into potential energy and at maximum height all kinetic energy will be converted into potential energy
So at maximum height 
Acceleration due to gravity 
So 0.50×9.8×h = 2.2
h = 0.4489 m
