The active element of a certain laser is made of glass rod 60.00 cm long and 3.00 cm in diameter. assume the average coefficient of linear expansion of glass is 9.0x10-6 /oc. if the temperature of the rod increased by 65 0c what is the increase in volume? express your answer in cm3.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
