Answer:
The temperature of the cooler substance was close to the room temperature. Therefore, the system experienced less change
Explanation:
Generally, in a closed system containing two bodies at different temperatures, there is a flow of heat energy from the body at a higher temperature to the body at a lower temperature. The effect is more significant when there is a large temperature difference between the bodies. However, if the temperature difference is small or insignificant, the change will be less.

Answer: 39.2m/s
Explanation:
Due to the free falling body, the acceleration of the ball is 9.8 m/s^2, and its initial velocity is 0 m/s.
V(t) = g*t
The change of velocity from t=1 to t=5:
Delta V = 9.8*(5-1) = 39.2 m/s
<span>The equation that relates force and torque is Torque = Force*length*sin(angle). Plug in the given values to the equation (convert length to meters first): -13 = Force * 0.35 * sin(30 degrees). Rearrange to solve for Force: Force = -13/(0.35 * 0.5) = -74.3 N (which is the same as a downward force of magnitude 74.3 N.</span>
Answer:
The frequency of the sound wave in the helium in the stopped pipe is 749.25 Hz.
Explanation:
Given that,
Length = 1.00 m
Temperature T = 20°C
Speed of sound = 999 m/s
We need to calculate the frequency of the sound wave in the helium in the stopped pipe
Using formula of frequency
Put the value into the formula
Hence, The frequency of the sound wave in the helium in the stopped pipe is 749.25 Hz.
