There are two main types of cometary tails: the ion and dust tail.
NOTE: you can use quizlet, is helps out a lot
The forces are applied in opposite direction.
So the net force will be the difference of both forces.
net force =5-3=2N
This force will be in direction of 5N(bigger force) means in direction which Andy is pushing.
Answer:
b. Specific heat increases as the number of atoms per molecule increases.
c. Specific heat at constant pressure is higher than at constant volume.
d. Monatomic gases behave like ideal gases.
Explanation:
Specific heat of the gas at constant pressure is usually higher than that of the volume.
i.e.
Cp - Cv = R
where R is usually the gas constant.
However, monoatomic gases are gases that exhibit the behavior of ideal gases. This is due to the attribute of the intermolecular forces which plays a negligible role. Nonetheless, the case is not always true for all temperatures and pressure.
Similarly, the increase in the number of atoms per molecule usually brings about an increase in specific heat. This effect is true as a result of an increase in the total number associated with the degree of freedom from which energy can be separated.
Thus, from above explanation:
Option b,c,d are correct while option (a) is incorrect.
I think it’s C not sure tho
