Objects 1 and 2 attract each other with a electrostatic force of 36.0 units .If the charge of object 1 is doubled AND the charge of object 2 is tripled ,then the new electrostatic force will be __ units

What ia the energy of an object because of its potential and kinetic energies

Elements that have one valence electron and are very reactive are called

Aspring has a relaxed length of 33 cm (0.33 m) and its spring stiffness is 6 n/m. you glue a 76 gram block (0.076 kg) to the top of the spring, and push the block down, compressing the spring so its total length is 15 cm. you make sure the block is at rest, then at time t=0 you quickly move your hand away. the block begins to move upward, because the upward force on the block by the spring is greater than the downward force on the block by the earth. calculate y vs. time for the block during a 0.09-second interval after you release the block, by applying the momentum principle in three steps each of 0.03-second duration.
