An object with a mass of 20 kg has a net force of 80 n acting on it. what is the acceleration of the object? 0.25 m/s2 4 m/s2 60 m/s2 100 m/s2

This is the substance(s) formed in a chemical reaction.

How is zig zagging a form of acceleration?

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.
