Try it yourself: A car's acceleration is -3.0 m/s?. At time 0 its velocity is +14 m/s. What happens to the
velocity of the car? Whats the veocity after 3 s?

i think it would be 5

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

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.
