Most earthquakes occur along or near the edges of the earth's lithospheric<span> plate. </span>
        
             
        
        
        
Answer:
H = start height (v = 0)
h = present height
v = present speed
assuming no friction
total energy = PE + KE
mgH = mgh + .5mv^2
if PE = KE then
mgH = mgh + mgh
h = H/2
potential energy = kinetic energy when object is at half its start height.

Answer:

Explanation:
F = Magnetic force = 4.11 N
 = Net current
 = Current in one of the wires = 7.68 A
B = Magnetic field = 0.59 T
 = Angle between current and magnetic field = 
 = Length of wires = 2.64 m
 = Current in the other wire
Magnetic force is given by

Net current is given by

The current I is 
.
