D. the pressure is not high enough for the electrical current to flow in the right direction and the battery has stalled
Answer:
53.4 gMol-1
Explanation:
Let the mass of the unknown gas be M
Let the molar mass of hydrogen gas be 2×1=2gMol-1
Time for diffusion of unknown gas = 12.5 min
Time for diffusion of hydrogen= 2.42 min
From Graham's law:
t1/t2=√M1/M2
Hence:
2.42/12.5= √2/M
Hence M= 53.4 gMol-1

Explanation:
Answer:
It will take 140.76 seconds to swim 0.150 miles.
Explanation:
Distance covered by man by swimming for t time= d
d = 1500.0 miles
t = 14 minutes + 34.56 seconds
1 min = 60 seconds
t = 14 × 60 seconds + 34.56 seconds = 874.56 seconds
Speed of the man while swimming = S = 
If the man swims 0.150 miles with the same speed ,then the time taken by him be T.
0.150 miles = 0.150 × 1609.34 m = 241.401 m
(1 mile= 1609.34 meters)


T = 140.76 seconds
It will take 140.76 seconds to swim 0.150 miles.
