Only electromagic waves cam travel in a vacuum. because they do not need a medium.
5.47 m
The bullet undergoes a non-elastic collision with the block of wood and momentum is conserved. The initial momentum is 0.029 kg * 510 m/s = 14.79 kg*m/s. The combined mass of the block and bullet is 1.40 kg * 0.029 kg = 1.429 kg. Since momentum is conserved, the velocity of both combined will then be 14.79 kg*m/s / 1.429 kg = 10.34989503 m/s.
With a local gravitational acceleration of 9.8 m/s^2, it will take 10.34989503 m/s / 9.8 m/s^2 = 1.056111738 s for their upward velocity to drop to 0, just prior to descending.
The equation for distance under constant acceleration is
d = 0.5 A T^2
so
d = 0.5 * 9.8 m/s^2 * (1.056111738 s)^2
d = 4.9 m/s^2 * 1.115372003 s^2
d = 5.465322814 m
Rounding to 3 significant figures gives a height of 5.47 meters.
Answer:
the final pressure = 1120 torr
Explanation:
In the starting, when a 10-L drum consist 6 L of ether at 18°C
Volume of gas
Total pressure of gas which is equal to Atmospheric Pressure = 760 Torr
vapor pressure of liquid (ether) = 400 Torr
vapor pressure of air
when the drum top is sealed & dented to 8 L capacity
Volume of gas
Total pressure of gasses
vapor pressure of ether
vapor pressure of air
But some of the liquid (ether) vapor will condensed into liquid just to maintain the vapor pressure of ether at 400 Torr )
therefore, the final pressure
