A36.0-kg child swings in a swing supported by two chains, each 2.94 m long. the tension in each chain at the lowest point is 416 n. (a) find the child's speed at the lowest point. (no response) m/s (b) find the force exerted by the seat on the child at the lowest point. (ignore the mass of the seat.

v=6.25 m/s

Explanation:

Given

mass of child

Length of chain

Tension in each chain

according to figure

Force exerted by the seat will be equal to the tension forces i.e. 2T

Force exerted by seat

show the wavelengths of a wave. show the crests of a wave.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
