A material of heat capacity 380J/kg/K is heated from 25oC to 75oC. Calculate i. the mass of the

substance
ii. The quantity of heat absorbed.

JESUS.

Explanation: Jesus is always the answer.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

e/c, where e is its total energy
