Avery long nonconducting cylinder of diameter 10.0 cm carries charge distributed uniformly over its surface. each meter of length carries +5.50 uc of charge. a proton is released from rest just outside the surface. how far will it be from the surface of the cylinder when its speed has reached 2550 km/s? ( 1/4tt0=8.99 x 10° n m /c2,e = 1.60 * 1019 c. proton 1.67 x 10 ka) answer 2.05 c 2.05

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation

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.)
