Without counting wind resistance, They will both reach the ground at the same time. If we apply the concept of kinematics, such as the equation vf^2=vi^2 + 2ad. This equation doesn't count how big or how heavy the mass is, it only focuses on how fast where they in the start and how far are both of them from the ground. So if they both have the same distance and same initial veloctity, then they will reach the ground at the same time.
For example, Try dropping a pen and a paper(Vertically) at the same height, you'll see they'll reach the ground at the same time.
If you count wind resistance, the heavier ball will hit the ground faster, because the air molecules will resist the lighter ball compared to the heavier ball.
Answer:
<h2><u>Refrigerator</u> is a liquid or substance that absorbs and releases thermal energy.</h2>
Explanation:
- Refrigerator creates liquid by increasing the pressure of the refrigerator vapor inside and forcing them outside the refrigerator into the coils.
- This is the process which leads to the conversion of the hot gas in the refrigerator coils into liquid form.
- The liquid form of the refrigerator subsequently absorbs the heat that is created inside the refrigerator thereby cooling the air inside and releasing thermal energy in the process.
I believe it is, All of the above.
Answer:
The moment of inertia will be increased by a factor of 1575
Explanation:
Let the moment of inertia of a wheel be given as;
where;
I is the moment of inertia of the wheel
m is mass of the wheel
r is radius of the wheel
when the mass is increased by a factor of 7 and the radius is increased by a factor of 15
Thus, the moment of inertia will be increased by a factor of 1575
I would say a because it just sounds right. I would've helped u if u had a real question question.
