A 4.50 kilogram block of wood at 20.0ºC is uniformly heated using 90,000. joules of heat. What will be the resulting temperature of the block? (Cp for wood = 1,800. J/kg-ºC)

If a clock aboard a space ship traveling at 0.900 c of the speed of light relative to earth chimes once at the beginning of the hour and again when it reads one hour later, how much time would an observer on earth say elapsed between the two chimes?

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.
