Which of the following is not true about energy conversion devices?

a. total energy input = useful energy output
b. total energy input = total energy output
c. total energy input = useful energy output + energy dissipated to the surroundings
d. total energy input = total energy output / efficiency

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
