Determine the force of gravitational attraction between the earth (m = 5.97 x 10 24kg) and a 70 kg physics student if the student is in an airplane 40,000 feet above the earth’s surface. The earth’s radius is 6.38 x 10 6m.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

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.
