The masses for Earth and the Moon are listed below along with the average distance between their centers. Earth's mass = 5.98 x 1024 kg Moon's mass = 7.36 x 1022 kg Distance = 3.84 x 108 m What is the attraction due to gravity of the Moon on Earth?

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
