Explanation:
When she releases the ball, it has some of both. (C)
Neither the opposite direction (left) or its slowing down. Hope this helps
Answer:
Explanation:
Energy stored in a capacitor is given by the expression
E = Q² / 2C , where Q is charge on it and C is its capacitance . As we put dielectric slab between the plates , capacitance increases , Due to it energy decreases as capacitance form the denominator in the formula above and Q is constant .
Hence energy decreases.
Angle at which under water diver sees the sun from horizontal = 
Angle from normal direction = 90 - 57 = 
Refractive index of water = 1.33
Refractive index of water = 1
We have the equation
1.33 * sin
= 1 *sin 
= 
This angle is angle from normal, so angle seen by fisherman from horizontal = 90 - 46.42 =
