Determine explicitly whether the following quantities are invariant under galilean transformation between two inertial frames.
a. work
b. translational kinetic energy
c. center of mass
d. moment of inertia
e. power

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

How are positive ions different from neutral atoms

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
