I think through convection I forget. Plus its enclosed (and, well closed)
Answer:

Explanation:
given,
Wave vibrates = 37.6
time = 27.9 s
maximum distance travel = 450 cm
time = 11.3 s
wavelength = ?
frequency of wave

f = 1.35 Hz
Speed of wave

v = 39.82 cm/s
wavelength of wave
v = fλ



Hence, wavelength of the wave is equal to 25.79 cm.
Explanation:
Below is an attachment containing the solution.
Answer:
Each object exerts a force on the other, and the two forces are equal and in opposite directions
Explanation:
Newton's 3rd Law Of Motion:
For every action, there is an equal and opposite reaction.
Without an external agent doing work, heat will always flow from a hotter to a cooler object. Two objects of different temperature always interact. There are three different ways for heat to flow from one object to another. They are conduction, convection, and radiation.
