A beam of light in air strikes the surface of a smooth piece of plastic having an index of refractionof 1.55 at an angle with the normal of 20 degrees. The incident light has component E-field amplitudes parallel and perpendicular to the plane of incidence of 10.0 V/m and 20 V/m respectively. Determine the corresponding reflected field amplitudes. (10 Points)

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
