The heavier bob has more kinetic energy/potential energy/momentum for any given amplitude of the two pendulums due to its larger mass, as each of these three quantities depend linearly on mass. The dampin...
Use energy difference between ground and first level to find E1-E0. Energy of the electron a nth energy level is found using En = (n^2pi^2hbar^2)/2mL^2Where n is the energy level plus 1, pi and h...
The answer is C) 10A Fuse.To calculate the current flowing to the kettle, you use the P=IV equation to work out that I=P/V. Putting P = 1200 and V = 230 into this equation gives I = 1200/230 = 5.217A. The...
The principle to use here is the principle of conservation of linear momentum, the question asks whether we have to modify this principle or use it in a different way to solve physics problems that have a...
We know Newton's Law of Gravitation, which states that the force F between two bodies of masses M and m respectively, separated by distance R, can be given by: F = GMm/R<...
