How is the weight of an object in a spaceship near the moon related to the distance that the spaceship is from the moon? A) Ther
2 answers:
Answer:
B) As the distance to the moon decreases, the weight of the spaceship would increase.
Explanation:
The weight of an object(w) is given as,
where,
m = mass of the object
g = acceleration due to gravity
As the spaceship will move closer to the Moon, impact of its gravity on the spaceship will increase as gravitational force is inversely proportional to the distance between two objects. In turn the weight of the space ship will also increase.

Answer:
Explanation:
Let suppose that centrifuge is rotating at constant angular speed, which means that resultant acceleration is equal to radial acceleration at given radius, whose formula is:
Where:
- Angular speed, measured in radians per second.
- Radius of rotation, measured in meters.
The angular speed is first determined:
Where is the angular speed, measured in revolutions per minute.
If , the angular speed measured in radians per second is:
Now, if and
, the resultant acceleration is then:
If gravitational acceleration is equal to 9.807 meters per square second, then the radial acceleration is equivalent to 1006.382 times the gravitational acceleration. That is:
