An ethernet cable is 4.15 m long. the cable has a mass of 0.195 kg. a transverse pulse is produced by plucking one end of the taut cable. the pulse makes four trips down and back along the cable in 0.820 s. what is the tension in the cable?

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.

What causes the development of most clouds and precipitation in the atmosphere?
