The answer is (C) 4 beats per second. The number of beats is computed as the difference between the frequencies of the two tuning forks. Plugging in the frequency values yields a result. Thus, the number of observable beats per second will be 4.
The answer is:
Details are as follows:
According to the problem, we have
The combined mass of A and B is 60kg
A's speed is 2m/s
B's speed is 1m/s
The mass of the bag is 5kg
Typically, the momentum of astronaut A along with the bag is defined by
To prevent a collision, astronaut A should maintain a speed that is either equal to or less than astronaut B's speed
Thus, the minimum speed astronaut A should achieve corresponds to that of astronaut B, which is 1
Consequently,
Answer:
The partial pressure of H2 is 0.375 atm.
The partial pressure of Ne also stands at 0.375 atm.
Explanation:
Mass of H2 = 1 g
Mass of Ne = 1 g
Mass of Ar = 1 g
Mass of Kr = 1 g
Overall mass of the gas mixture totals 4 g.
Pressure in the sealed container is 1.5 atm.
Calculating the partial pressure for H2 yields: (mass of H2/total mass of gas mixture) × pressure of sealed container = 1/4 × 1.5 = 0.375 atm.
Calculating the partial pressure for Ne similarly gives: (mass of Ne/total mass of gas mixture) × pressure of sealed container = 1/4 × 1.5 = 0.375 atm.
