Aloop of wire has the shape of a right triangle (see the drawing) and carries a current of i 5 4.70

a. a uniform magnetic ? eld is directed parallel to side ab and has a magnitude of 1.80 t. (a) find the magnitude and direction of the magnetic force exerted on each side of the triangle. (b) determine the magnitude of the net force exerted on the triangle.

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
