An 80.0-gram sample of a gas was heated from 25 °C to 225 °C. During this process 346 J of work was done by the system (which was stationary), and its internal energy increased by 7765 J. What is the specific heat capacity of the gas?

A motorcycle that is slowing down uniformly covers 2.0 successive km in 80 s and 120 s, respectively. Calculate (a) the acceleration of the motorcycle and (b) its velocity at the beginning and end of the 2-km trip.

Describe the difference between a field force and a contact force.

An electric field is e = 200 n/c i for x > 0 and e = - 200 n/c i for x < 0. a cylinder of length 20 cm and radius 3 cm has its center at the origin and its axis along the x axis such that one end is at x = + 10 cm and the other is at x = - 10 cm.
