A professor's office door is 0.89m wide, 2.0m high, and 4.0cm thick; has a mass of 25kg ; and pivots on frictionless hinges. A "door closer" is attached to the door and the top of the door frame.
When the door is open and at rest, the door closer exerts a torque of 4.5N?m.
What is the least force that you need to apply to the door to hold it open?
compute the force and the total work required in each case. Find the tension in each of the cables.
Four or five gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. Use the following specific heat capacity data to resolve which block will increase its temperature the most.
