A rectangular loop with sides of length a = 2.00 centimeter and b = 4.10 centimeter is located near a wire that carries a current that varies as a function of time: it=3.86 +1.36t2 where the current is in Amperes and the time is in seconds. The distance from the straight wire to the closest side of the loop is d= 0.230 centimeter. Determine the induced emf in the loop at time t= 1.10 seconds? (Note that positive emf is clockwise.)
A rock of mass 0.19 kg falls from restfrom a height of 12 m into a pail containing 0.30 kg of water. Therock and water have the same initial temperature. The specific heatcapacity of the rock is 1820 J/(kg·C°).
A 4.00 meter long rod is hinged at one end. The rod is initially held in the horizontal position, and then released as the free end is allowed to fall. Determine the angular acceleration as it is released
