Answer:
zero
Explanation:
There are three forces acting on the piston
1. force due to atmospheric pressure = F1 downward
2. force due to gaseous pressure = F2 upward
3. force due to the weight placed on the piston = F3 = mg downward
As the piston is in equilibrium condition, so the net force on the piston is zero.
Answer:
Increase the charge of one particle by a factor of 16
Explanation:
Answer:
233.1 miles per hours
Explanation:
Speed: This is defined as the ratio of distance to time. The S.I unit of speed is m/s. speed is a vector quantity because it can only be represented by magnitude only. Mathematically, speed can be expressed as,
S = d/t ....................... Equation 1
Where S = speed of the runner, d = distance covered, t = time.
Given: d = 100 meter , t = 9.580 seconds
Conversion:
If, 1 meter = 0.00062 miles
Then, 100 meters = (0.00062×100) miles = 0.62 miles.
Also
If, 3600 s = 1 h
Then, 9.580 s = (1×9.580)/3600 = 0.00266 hours.
Substitute into equation 1
S = 0.62/0.00266
S = 233.1 miles per hours.
Hence the runner speed is 233.1 miles per hours
