What is the value of the electric field .3 m from a square piece of metal which is 1.5 km x 2 km and has a net charge of 26 mC?

Lymphocytes known as blastocysts make antibodies that fight infection. select the best answer from the choices provided t f

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
