If an atom has 34 protons and 40 neutrons, what is its mass number?

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

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
