Combine the ideal mechanical advantages of each simple machine part of the compound machine. C. Combine the ideal mechanical advantage of the first and last simple machine in the compound machine. D. Divide the work output by the work input of the whole machine.

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

i would say

there are no atoms

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.
