Answer:
correct option is b. 31.3 m/s
Explanation:
given data
artificial gravity a1 = 1 g
artificial gravity a2 = 2 g
diameter = 100 m
radius r= 50 m
speed v1 = 22.1 m/s
solution
As acceleration is ∝ v²
so we can say
.....................1
put here value
solve it
v2 = 
× 22.1
v2 = 31.25 m/s
so correct option is b. 31.3 m/s

B. Asteroids have a nearly circular orbit.
Answer:
volume is 700 mL
Explanation:
pressure = 2 atm
volume = 350 mL = 0.350 L
to find out
volume
solution
we will apply here equation that is
P1×V1 = P2×V2 ..............1
here P1 = 2 and V1 = 0.350 and P2 = 1 for standard atmospheric pressure
so put all value here in equation 1 and get V2 volume
2 × 0.350 = 1 × V2
V2 = 0.700 L
V2 = 700 mL
so volume is 700 mL
