The elastic energy stored in your tendons can contribute up to 35 % of your energy needs when running. sports scientists have studied the change in length of the knee extensor tendon in sprinters and nonathletes. they find (on average) that the sprinters' tendons stretch 40 mm , while nonathletes' stretch only 33 mm . the spring constant for the tendon is the same for both groups, 31 {\rm {n}/{mm}} . what is the difference in maximum stored energy between the sprinters and the nonathletes?
express your answer using two significant figures in j.

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
