Answer:
Increases
Explanation:
The kinetic energy _____ (Increses)
as the roller coaster goes downhill
Answer:
Current = dQ/dt
or I = dQ/dt
Where I represents current.
Which is the rate of flow of charge.
Q=4 + 2t + t²
dQ/dt = 2 + 2t --- This is the relation that gives the instantaneous current.
At time t=2sec
dQ/dt = I = 2 + 2t
= 2 + 2(2)
=2 + 4
= 6A.
The Geosphere which is 99.94% of earths mass
Answer:

Explanation:
By conservation of the linear momentum:
m1*V1 = (m1+m2)*V2
Solving for V2:

The kinetic energies are:



Simplifying:

The ratio will be:
