Answer:
Okay let say from the diagram you have more force come in from the B point of the magnet and release out from A point of the magnet. so lets say north is always the attractive spot and south is your releasing spot.
Explanation:
meaning from magnet the north pole attracts objects and the south pole repeal object.
I would say D) two high tides and two low tides each day
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.
