Sound travels best in dense air because the molecules are close together than in less dense air.
Explanation:
Because the air is compressed in the balloon, the air molecules inside are closer together than the air molecules outside the balloon. Therefore these molecules inside the balloon can transmit the sound energy effectively. Remember sound waves are made by the transmission of the compression and rarefaction by the air molecules.
This is also the reason why solids are good transmitters of sound waves (and other mechanical waves) than air. The molecules of solids are more closely packed than those of air.

The image would be after the first focal point but before the lens and it will be smaller than the object. Look at my picture for reference. Please let me know if this helped you!
During its lifepsan, the sun's core would keep contracting and heating up.
The temperature will keep increasing to the point where the temperature outside the core will get to hydrogen fusion temperatures.
The sun will grow in surface and eventually became the Red Giant
Answer: Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +.
Hope this helps!
