Decreases
Explanation:
The acceleration due to gravity on a body decreases with depth.
Acceleration due to gravity is the change in velocity with time of a body as result of the pull of gravity or gravitational force.
- The acceleration due to gravity tend to pull all bodies to the center of the earth.
- As body moves away from the center of the earth, the pull becomes very more and acceleration increase.
- But when a body approaches the center of the earth, the acceleration reduces.
- At depth, the acceleration due to body of a body begins to decrease.

Answer:
the vibrations push the purse up and down very fast and gravity pushes the purse down onto the floor
Explanation: does that help
Yes is the answer for you
Answer: a) 23 m/s
Explanation: In order to solve this problem we have to consider the circular movement where the friction force change de direcion of the velocty to keep a circular trajectory.
By using Second Newton law, we have:
F=m*acentripeta
μ*N= m*v^2/r where N ( equal to mg) is the normal force and μ is the coefficient of friction. r is the redius of the trajectory.
so
the maximun speed permited to keep a circular trajectory is calculated as:
v= (μ*r*g)^1/2=(0.65*80m*9.8 m/s^2)^1/2=22.57 m/s
