Aglass ball of radius 3.74 cm sits at the bottom of a container of milk that has a density of 1.04 g/cm3. the normal force on the ball from the container's lower surface has magnitude 9.03 x 10-2 n. what is the mass of the ball?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.

Energy transformations that involve one transformation from one type of energy to another are called transformations.
