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<...
An elastic collision is a collision where there is no loss of kinetic energy. Therefore, it can be said that, since KE is conserved, momentum is conserved. In other words the momentum and total kinetic en...
Current is a measure of the rate of change of charged electrons going through the wire. Therefore, when the current increases more electrons are passing through the wire in a unit time. Thus, their averag...
