A1.5 kg orange falls from a tree and hits the ground in 0.75s. what is the speed of the orange just before it hits the ground?

7.35 metre/second

Explanation:

According to first equation of motion for falling body Vf = Vi+gt

Initial velocity Vi =0, gravity g = 9.8, time t = 0.75s

Final velocity just before it hits the ground Vf = 0+ (9.8)(0.75)--> Vf=7.35m/s

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.
