Given that E2 = c2p2 + mo2c4-----------(1); where p represents the relativistic momentum p=\gammamou, show that m=(p2c2-T2)/(2Tc2) where m is the relativistic mass of the particle,and T it's kinetic energy. Homework Equations E= T+moc2-------(2) The Attempt at a Solution I...

1. I have a rod of length 4,cross section 1 and thermal conductivity 1.Nothing is mentioned about the end at the origin x=0, but at the opposite end x=4, the rod is radiating heat energy at twice the difference between the temperature of that end and the air temperature of 23 celsius. Find the...

i say 60N aswell

The question :Two rods L1 and L2 of different materials( hence different thermal conductivities) and different cross-sectional areas,are joined at x=a. The temperature is continuous, And NO HEAT ENERGY IS LOST AT a, so all heat energy that flows from L1 flows into L2. ? What equation...
