The Heisenberg Uncertainty principle states that ΔxΔp > h/4π. What is represented by the terms Δx, and Δp? What can we say about p if the precise value of x is known? What does this mean for experimental results.

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

When a toothbrush is charging, p.d. across the primary coil is 230 V, p.d. across the secondary coil is 7.2 V. The primary coil in the charging base has 575 turns of wire on its coil. Find the number of turns on the secondary coil inside the toothbrush.

This question is on transformers. This is clear because there is a primary and secondary coil and a different voltage between the 2 coils. Transformers induce a changing voltage in a coil. The known equat...

Describe and explain the motion of a skydiver from leaving the aircraft to reaching terminal velocity

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 ...

How do I do uncertainties properly?

All uncertainties show you is the range your answer will fall in. First off, when you do the experiment, any analogue scales will have an uncertainty of half their lowest unit and digital scales will be t...
