A carrot hangs from the ceiling by a rope,
2 answers:
Answer: Diagram B
Explanation:
A free body diagram shows the forces acting on an object in a certain scenario.
In this scenario there are two forces acting on the carrot: the Tension force (Ft) from the rope that the carrot is hanging from and Gravitational force(Fg) which is pulling the carrot to the Earth.
The diagram depicting this is diagram B.

Answer:
counterclockwise
Explanation:
= Small drive wheel radius = 2.2 cm
= Angular acceleration of the small drive wheel =
= Radius of pottery wheel = 28 cm
= Angular acceleration of pottery wheel
As the linear acceleration of the system is conserved we have
The angular acceleration of the pottery wheel is .
The rubber drive wheel is rotating in clockwise direction so the pottery wheel will rotate counterclockwise.
= Initial angular velocity = 0
= Final angular velocity =
t = Time taken
From the kinematic equations of linear motion we have
The time it takes the pottery wheel to reach the required speed is
