After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 51.0cm . The explorer finds that the pendulum completes 109 full swing cycles in a time of 126s .
Part A Find the period of the pendulum
Part B What is the magnitude of the gravitational acceleration on this planet?
Rank the vector combinations on the basis of their angle, measured counter clockwise from the positive x axis. Vectors parallel to the positive x axis have the angle of 0. All angle measures fall between 0 and 360.
Three charged particles are placed at corners of an equilateral triangle of side 1.20m. The charges are + 7.0 mc,-8.0 mc and -6.0 mc compute the magnitude and direction of the net force on each due to the other two.
