I would say the correct answer would be light travels faster in medium 3 then medium 2.
I think is True! Is the best answer. Because the trumpet it make them sounds like the lips with the musician and it vibrate.
Answer:
B
Explanation:
The object with the most thermal energy is the choice B. This is because from the given choices, it has the most mass and highest temperature of all the bricks.
Thermal energy is the sum total of the average kinetic energy within the system.
It is mathematically expressed as:
Quantity of energy = mass x specific heat x change in temperature
We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.
in ideal gas we have few things that we need to follow as following
1. Force of interaction between gas molecules are negligible.
2. There is no effect of gravity on them
3. All collisions are perfectly elastic collision.
4. there will be no energy loss
5. All newton's law are valid for them.
6. all molecules moves with same speed in random direction.
So here in order to follow all above conditions we have to maintain low pressure and high temperature in the gas due to which the density of gas becomes low.
So correct answer will be
<em>The gas density is low and the temperature is high.</em>
