Explanation:
Initial velocity is 25m/s i.e. u. Final velocity would be zero since the bus stopped. It is noted that the bus deccelartion of 4m/s, so the acceleration should be considered negative of 4m/s I.e. 4m/s. So using third law of motion i.e.
v^2 - u^2= 2as
(0)^2 - (25)^2= -2×4×s {Note here I used minus sign in acceleration}
-625 = -8×s
s=625 ÷ 8
s= 125 m
So bus would cover a distance of 125m before coming to rest.

A thermos keeps thing hot or cold by using vacuum technology to keep air from getting inside. The double walled feature of the cup is what allows the container to be "vacuum sealed". In manufacturing the air between the two walls is removed creating the seal. The lack of air keeps the heat or cold from transfering, therefore letting it remain basically the same temperature.
