Avery long rod 5 mm in diameter has one end maintained at 100°c. the surface of the rod is exposed to ambient air at 25°c with a convection heat transfer coefficient of 100 w/m2.k. determine the heat lost from the rod if it is made of pure copper (k 398w/m. k), 2024 aluminum alloy (k = 180 w/m. k) and aisi 316 stainless steel (k = 14 w/m. k).

A2 kg ball travellng to the right with a speed of 4 m/s collidees with a 5 kg ball traveling to the left with a speed of 3 m/s. take right to be the positive direction. what is the total momentum of the two balls before they collide? what is the total momentum of the two balls after they collide?

How will the system respond to a temperature increase?

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.
