Consider a father pushing a child on a playground merry-go-round. the system has a moment of inertia of 84.4 kg · m2. the father exerts a force on the merry-go-round perpendicular to its radius to achieve an angular acceleration of 4.44 rad/s2.

The torque acting on the body is,  τ = 374,736 kg m² s⁻²

Explanation:

Given data,

The moment of inertia of merry go round, 'I' = 84.4 kg m²

The angular velocity of merry go round, 'α' = 4.44 rad/s²

Substituting the values,

                                        τ = 84.4 kg m² x 4.44 rad/s²

                                           = 374,736 kg m² s⁻²

Hence, the torque acting on the body is,  τ = 374,736 kg m² s⁻²

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
