an airplane flies 120 km at a constant altitude in a direction north of east. a wind is blowing that results in a net horizontal force on the plane due to the air of 2.40 kn in a direction 10.0° south of west. how much work is done by the air on the plane?

explanation:

an enlarged virtual image is the answer

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
