g 9. A block of mass 10 kg is pulled by a 30 N force at a constant velocity along a flat surface. The coefficient of kinetic friction between the block and the surface .

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

Amagnetic field applies forces on: a)static chargesb)moving chargesc)water flow

In this thread, i would like you to comment on the nature of light and how operation of telescopes. light has a duality of a particle and a wave; which one affects your life? also how does light interact with optics inside telescopic systems? answer these questions in two paragraphs. then respond the another students response.
