The cosmic microwave background radiation, the remnant of the radiation produced in the original big bang explosion, appears to us to be not quite uniform in temperature or intensity in all directions—that is, it is not isotropic. why is this?

If steel is more dense that lake water, why can a boat float

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

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.
