Answer:
0.0316 m
Explanation:
Wok done = Energy change
Work done on the spring = Energy change of the block
Elastic Potential stored = Kinetic energy of the block
x = 
x = 
x = 0.0316 m
k = spring constant
m = mass of block
v = velocity of the block
x = compression of spring
Answer:
Since formula for current is
I = Q/t
or
Current = Charge / Time
to increase current, the charge must be increased per unit time.
Answer:
pressure= force/area
A solid resting on a horizontal surfaceexerts a normal contactforce equals to its weight. The pressure of the solid on the surface depends on the area of contact. (b) the area of contact between the two surfaces. The greater the force or the smaller the area the greater the pressure.
