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
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...
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...
Electric Field Repulsion - 90N Gravitation Field Attraction - 7.3x10^-35N
The primary equation in this calculation is rho = RA/L Where rho is resistivity, A is cross sectional area, L is length, and R is resistance
The resistance and length are given in the question. Res...
