On the way to your friend’s house, you run out of gas and try to push your 1,350kg car to the gas station. You give the car your best push and it accelerates 1m/s2. Calculate the force you applied to your car. Be sure to show all math work and include units.

Describe how the fermi level changes with donor level, temperature and contact with p and n type semiconductors

True or false graphs must include scales that increase by the same amount

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.
