Naim Suleimanoglu of Turkey has a mass of about 67 kg. (This feat has earned Suleimanoglu the nickname of “Pocket Hercules.”) If the potential energy associated with a barbell lifted 1.56 m above the floor by Suleimanoglu is 2.09 X 103 J, what is the barbell’s mass?

The plum pudding model of the atom states that ?

The mini-refrigerator fire was most likely caused by what type of wiring?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
