1. Δx and Δp represent the uncertainty in position and the uncertainty in momentum respectively.
2. If x is known absolutely then p cannot be known at all.
3. This means that the precise p...

Initially, there is only one force acting on the skydiver, which is their weight. F=ma therefore mg=ma. The m's cancel and the skydiver falls with acceleration g. However as soon as they have a downwards ...

The induced e.m.f. is equal to the rate of change of magnetic flux linkage. Can use equation with all terms defined.

The important condition for circular motion is that there must be a constant force acting perpendicular to the motion of the object. In this case there will be a contact force acting on the object from th...

When anything is hit it will vibrate at the same frequency regardless of the force that hits it. This frequency of un-damped oscillations is the natural frequency. And every object/system has its own set ...
