The device pictured is called a velocity selector. Two charged plates are placed in a uniform B-field, so that the direction of the E-field between them is at a right angle to the direction of the B-field. Charged particles are then sent through the plates. Only those for which the electrical and magnetic forces exactly cancel out are allowed to pass to the far end. If we send hydrogen nuclei (that is, protons) into the selector with the strength of the E-field at 2000 N/C and the strength of the B-field at 0.8 T, what is their velocity if they make it through

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
