What would be the ratio of power loss of a transmission line carrying 1,000 amperes at 1,000 volts as compared to 10 amperes at 100 kilovolts? assume a resistance of 1 ohm on the transmission line?

Can you think of a way a rock unit with an older fossil could be above a rock until with a younger fossil? describe the scenario.

As the distance from a magnet increases, what happens to the magnet force?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
