Maximum elemental U-value = 0.22 W/m2°C The insulation thermal conductivity = 0.03 W/m°C
Determine the minimum thickness of insulation need to be fixed above the newly proposed 6mm thick ceiling having k-value = 0.102 W/m°C

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
