Specific heat of air at constant pressure = 1.005KJ/kg-K Apparently the hot air leaves the house while equal quantity of the cool air passes inside (Neglecting the small specific volume changes between the hot and the cold air) So the situation can be sampled as a scenario where there is continuous draw down of the thermal energy from the air.
Answer:
big
Explanation:
if its big Ryan it gives it a lot of momentum because the bigger the more distance covered
Answer:
0.02
Explanation:
Force, 
where N is normal reaction and coefficient of kinetic friction is 
. Also, N is equivalent to mg ie N=mg where m is mass of an object and g is acceleration due to gravity. Making 
the subject of the formula then
Substituting F with 2 N, m with 10 kg and g with 9.81 then
The answer is 3 I hope I helped
Answer:
an object's apparent weight is its mass multiplied by the vector difference between the gravitational acceleration and the acceleration of the object.
