Radar bounced off of the Moon returns to Earth in 2.53 seconds. The velocity of the radio waves that comprise the radar beam is 3.00 x 108 m/sec. How far
is the one-way distance from Earth to the Moon? Think carefully about how far
the beam had to travel to go to the Moon and back again.

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative

A1.5m wire carries a 2 a current when a potential difference of 52 v is applied. what is the resistance of the wire?

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
