Why are transformer cores made of laminated, rather than solid, magnetic material?
 
  What will be an ideal response?

Question 2

A 2.0 kg softball is pitched to you at 20. m/s. You hit the ball back along the same path, and at the same speed. If the bat was in contact with the ball for 0.10 s, the average force the bat exerted was
 
  A) 0.40 kN.
  B) 40. N.
  C) zero.
  D) 0.80 kN.
  E) 0.65 kN.

Answer to Question 1

The changing flux in the transformer core tries to induce currents in the core material. These currents would lead to energy loss and undesirable heating effects. Lamination reduces the current flow and loss.

Answer to Question 2

D
