Answer:
Explanation:
The artificial gravity generated by the rotating space station is the same centripetal acceleration due to the rotational motion of the station, which is given by:
Here, r is the radius and v is the tangential speed, which is given by:
Here is the angular velocity, we replace (2) in (1):
Recall that .
Solving for :
Answer:
The correct option is B
Explanation:
In part A pressure is given as
In Part B we can calculate the pressure using the formula
Where F is the force which in this case is weight which can be obtained as follow
W = Mg
Substituting 70kg for M and for g
A is the area with a value
So substituting into the above equation
for part c
A
F
Therefore
From this we see that the value of P for part B is the greatest
