Answer:
Explanation:
Given;
The operational pressure of the cooker, 
area of the opening, 
- We know that the gauge pressure is measured with respect to the atmospheric pressure. As the atmospheric pressure acts on all the components of the system being observed so, we only need to counter the gauge pressure.
As the petcock sits on the opening of the cross-section so, it balances the built-in pressure due to its weight.
<u>Hence:</u>
where:
mass of the petcock
acceleration due to gravity
The angle theta of the spring is 31 degrees. To solve for this, show the equation which is equal to the 10lb ball. With this, the unknown will be the angle. Then transpose/transfer the terms in order to isolate the variable for the angle. First solve for s, then solve for angle theta. You will come up with s = .5849 ft and angle theta = 31.2629 or 31 degrees. Hope this helps.
It would swim 30*15 metres, which is 450 metres.
Answer:
Millikan's oil drop experiment proved that electric charge is quantized.
At the time, there was still great debate whether electric charge was continuous or not.
Millikan believed that there was a smallest unit of charge, and he set out to prove it.
This was the big result of the oil drop experiment.
That he could also determine the charge of the electron was a secondary benefit.
This was probably one of the most significant experiments ever carried out.
