* The 'emf generated by a copper-constantan thermometer is 15 mv. If the cold junction is at a temperature of 20 degrees celcius. Calculate the temperature of the hot junction when sensitivity
of the thermocouple is 0.03mv/degree celcius

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Apiece of metal with a length of 1.42 cm was measured using four different instruments. which of the following measurements is the most accurate?

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
