an object with a mass of 2.4 kg has a force of 12.6 N applied to it. What is the resulting acceleration of the object?

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?

Match each scenario to the form of energy it represents
