a very heavy wrecking ball is attached to a much lighter chain and is dangling from a crane and swinging back and forth. As long as it does not swing too high the time it takes the wrecking ball to complete one full oscillation will be independent of A) the weight of the ball, but not the amplitude of the motion.B) both the amplitude of the motion and the weight of the ball.C) both the length of the chain supporting the ball and the amplitude of the motion.D) the amplitude of the motion, but not the weight of the ball.

Answer:

B) both the amplitude of the motion and the weight of the ball

Explanation:

Time period of a pendulum is given by

T=2\pi \sqrt{\dfrac{L}{g}}

where,

L = Length of pendulum

g = Acceleration due to gravity

The system here is similar to a simple pendulum

It can be seen that the time period depends on L and g.

Amplitude and weight are the factors that do not determine the time period.

Hence, the answer is B) both the amplitude of the motion and the weight of the ball

Verizon [17]
The functions of angles are used to find unknown lengths or angles that can't be measured, in terms of known quantities. The trig functions of angles are ratios of lengths, so they're bare naked numbers without units.

How will physical and/or chemical weathering contribute to create rounded shapes during spheroidal weathering?
Vilka [71]
Chemical weathering weakens the outer surfaces of rocks and its primary agent is water. Mechanical weathering is carried out by impact or attrition by water and air.
Both of these forms of weathering combine and cause rocks to obtain a spherical shape.The concentric layers of rock are combined to form structures known as saprolite.
