Answer: 0.09 m
Explanation:
Centripetal acceleration in terms of tangential speed is:
where r is the radius.
It is given that,
centripetal acceleration of the mouse,
tangential speed ,
Radius of salami is:
Thus, the radius of the salami is 0.09 m.

Answer:
The correct answer to the question is
B. It always decreases
Explanation:
To solve the question, we note that the foce of gravity is given by
where
G= Gravitational constant
m₁ = mass of first object
m₂ = mass of second object
r = the distance between both objects
If the mass of one object remains unchanged while the distance to the second object and the second object’s mass are both doubled, we have
=
Therefore the gravitational force is halved. That is it will always decrease
