Determine the angles made by the vector v = (-36)i + (29)j with the positive x- and y-axes (enter the smallest possible positive values). write the unit vector n in the direction of v.

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

Which of the following are not typically included in the periodic table? a. atomic mass b. element symbol c. isotopes d. number of electrons

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
