I place two positive charges Q1 = 15 nC and Q2 = 5 nC a distance 2 meters apart. What is the magnitude of the electric field exactly halfway between them, in N/C?

radiation warms things up temp rises convection currents air circ windy weather

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

this would be about 43%
