Question

Is the change in kinetic energy is only due to tangential force?

Answer 1

KE is a scalar /quantity.Inuniform circular motion the direction of a velocity is continuously changing but its magnitude not .now KE =1/2 m v^2 here all scalar property is constant so Kinetic Energy does not change. Therefore kinetic energy will only depend on speed; direction change will have no effect on energy.

Answer 2

Explanation:

A hypotonic solution is any solution that has a lower osmotic pressure than another solution. In the biological fields, this generally refers to a solution that has less solute and more water than another solution.
