The deeper the diver takes the helium balloon, the more it reduces in size. This is due to the pressure of the water column above pressing on the balloon. According to Boyle’s law (P= k*1/V.), as the volume of the balloon decreases, the pressure of the helium inside increases.
Answer:
about 36.10 g
Explanation:
The proportion of interest is ...
mass/atoms = x/(1.810·10^24) = (12.0107 g)/(6.02214076·10^23)
Multiplying by 1.810·10^24, we find the mass of the sample to be ...
x = 36.0991 g
The mass of the sample is about 36.10 grams (to 4 s.f.).
<span>The instructor should be questioned to see if the filtrate is able to be recycled. This precipitate can contaminate the filtrate, rendering it useless for repeated experiments. If it is able to be recycled, a second pass through the filter might be required to remove the precipitate.</span>
Answer:
The runner should run 51 minutes.
Explanation:
Distance wished by runner to cover = d = 10.4 km
Time taken by the runner to cover 10.4 km = T
Speed of the runner = 7.6 mile/hour
1 mile = 1.60934 km
1 hour = 60 min
The runner should run 51 minutes.
