<h3><u>Given </u><u>:</u><u>-</u></h3>
- The mass of the body is doubled
- The height of the body is constant
<h3><u>Solution </u><u>:</u><u>-</u><u> </u></h3>
We know that ,
Potential energy = mgh
<u>Therefore</u><u>, </u>
We can say that,
PE is directly proportional to Mass of the body
<u>According </u><u>to </u><u>the </u><u>question</u><u>, </u>
PE of the body = 2m * g * h. ...eq( I)
From (I) , we can conclude that, If mass of the body get doubled then its PE will also be doubled .
Nothing has been discovered to go faster than the speed of light. There have been some discoveries that had a speed very, very close to it (a bit under it), but none have passed it.
Answer:
Explanation:
The axle is the shaft that the wheel is mounted on
The force applied to the rim of the wheel produces a torque = force * distance = 120N * 1.38m (Nm)
The torque applied to the axle must balance this, therefore the force = 120N * 1.38/0.09
=1840N
The answer is 179J let me know if you need the work
