Answer:
Option A: none
Explanation:
Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass.
From the question, the parameters given are; The heat of vaporization of nitrogen= 48 cal/g and that of water is 80 cal/g.
Using the formulae; Specific heat capacity,c= Q/ m× ∆T,----------–-----------------------------------------------------
STEP ONE: We will have to calculate all the energy numbers; 77k is approximately the boiling point of Nitrogen.
Energy required to decrease water from 15°C to 0°C = E(1).
0.1×10^3 g× 48 cal/gram..
= 4800 cal
Energy require to vaporize Nitrogen=E(2).
= 80 cal per gram×0.15(15-0)
= 180 cal
Energy required to decrease water from 15°C to 0°C is higher than that of the energy to vaporize Nitrogen, N2.
STEP 2: 180/4800× 15 = 0.5625
Therefore; 15-0.5625 =14.43
Answer= 14.43gC

Answer:
1)every planet move in elliptical path.
The best answer would be the second option B) because that is NOT part of the Kinetic Molecular Theory.
Answer:
From the equation ΣF = ma, one can say that the mass is 1800 kg, and the acceleration of gravity is -9.8 meters. Multiply those together and it is -17640 newtons.
