Here are some videos and links that will help you with each question.

Question 1 (resistance, electrical power and thermistors)

R=V/I, E=P/t

Remember to convert time into seconds.

Thermistors

Question 2 (size of atom, ionisation, alpha, beta and gamma)

Question 3 (renewable energy, KE and GPE calculations)

Renewable sources of energy – https://www.bbc.co.uk/bitesize/guides/z2wfxfr/revision/2

Kinetic Energy – You need to be able to rearrange for v

Gravitational Potential Energy Equation

Question 4 (density practical, resolution and errors)
