A moment about a point is the product of a force applied and the distance perpendicular to the line of action of that force. So M = F*d

The first and most important step is to highlight all the important information that is given in the question. Sometimes, it is very easy to miss out key numbers that you might require to get to the final...

For this we need to use a SUVAT equation. S=displacement U=initial velocity V=final velocity A=acceleration T=time In the question we are give U=0m/s since the ball is at rest to start with Since the ball...

Relevant equations: 1) frequency = 1/ time period; 2) v(max) = Amplitude*(2pifrequency)

First, we need to calculate the frequency of the baby's oscillation. That is, the number of times, p...

Young's modulus = stress/strain. Stress = F/A Strain= e/l. Measure the length of a wire between 2 points, placing a marker at each. Also measure the diameter to calculate the cross sectional area of the w...
