Apail of water is rotated in a vertical circle of radius r = 1.6 m . the acceleration of gravity is 9.8 m/s 2 . r v what is the minimum speed of the pail at the top of the circle if no water is to spill out? answer in units of m/s.

3.95 m/s

Explanation:

Given

radius of circle

Water will not spill if the centripetal acceleration is greater than acceleration due to gravity

i.e.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

think its the third option
