Answer:
h = 13.06 m
Explanation:
Given:
- Specific gravity of gasoline S.G = 0.739
- Density of water p_w = 997 kg/m^3
- The atmosphere pressure P_o = 101.325 KPa
- The change in height of the liquid is h m
Find:
How high would the level be in a gasoline barometer at normal atmospheric pressure?
Solution:
- When we consider a barometer setup. We dip the open mouth of an inverted test tube into a pool of fluid. Due to the pressure acting on the free surface of the pool, the fluid starts to rise into the test-tube to a height h.
- The relation with the pressure acting on the free surface and the height to which the fluid travels depends on the density of the fluid and gravitational acceleration as follows:
P = S.G*p_w*g*h
Where, h = P / S.G*p_w*g
- Input the values given:
h = 101.325 KPa / 0.739*9.81*997
h = 13.06 m
- Hence, the gasoline will rise up to the height of 13.06 m under normal atmospheric conditions at sea level.
Answer:
The maximum potential energy of the net, compared to its unstretched potential energy, is:
Explanation:
From the question we are told that
The weight of the man is
The distance of the window to the net is
The distance stretched by net is
Generally from the of conservation energy , the total energy is conserved
This implies that
Where is the initial potential energy of the , man which is mathematically evaluated as
Substituting values
And is the unstretched potential energy of the net
And is the final potential energy of the man which is mathematically evaluated as
Substituting values
The negative show that the direction of the man is against the direction of gravitational pull
And is the maximum potential energy of the net when stretched
So the above equation becomes
So
Answer:
61 ms
Explanation:
Given that
Length of the nerve call connecting the spinal cord to your feet, s is 1.1 m
Speed of the impulse of the nerve, v = 18 m/s
Time taken by the nerve to travel the distance, t = ?
In solving this, we'd apply the very most basic formula in physics. Formula of speed, with respect to time and distance.
Speed, v = distance, s / time, t
time, t = distance, s / speed, v
time, t = 1.1 / 18
time, t = 0.061 s, converting to milliseconds, we have, time, t = 61 ms
