I know this isnt work topic, but what do you think?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

The magnetic field inside a superconducting solenoid is 4.50 t. the solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. determine (a) the magnetic energy density in the field and (b) the energy stored in the magnetic field within the solenoid.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
