The length of a simple pendulum is 0.79 m and the mass of the particle (the “bob”) at the end of the cable is 0.24 kg. the pendulum is pulled away from its equilibrium position by an angle of and released from rest. assume that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion. (a) what is the angular frequency of the motion? (b) using the position of the bob at its lowest point as the reference level, determine the total mechanical energy of the pendulum as it swings back and forth. (c) what is the bob's speed as it passes through the lowest point of the swing?

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

explanation:

the masses of the objects and the distance between them

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
