They are 50 stars in the U.S flag.
The answer is solely based on the length of space between atoms. In gaseous mediums, atoms are generally quite far apart allowing waves to be undisrupted in the process. In solids and liquids, sound waves are trapped/diluted in the relatively close atom distances
The correct answer for this question would be option A. When the thermal energy in a hot iron flows into a shirt, what we can possibly say about this situation is that, the iron is warmer than the shirt. The transfer of heat from the iron to the shirt is called heat conduction. Hope this answer helps.
Answer:

Explanation:
As we know that here no friction force is present on the skier so we can say that total mechanical energy is conserved here
so we will have

now we will have



now we have



Answer:
Explanation:
From the given information:
Let the first weight be
= 80 kg
The weight of the buddy be
= 120 kg
The weight of Bubba be
= 60 kg
Also, since you and Budda are a distance of 4m to each other, then the length to which both meet buddy will be:

The length of the boat be
= 4 m
∴
We can find the center of mass of the system by using the formula:
