A taser sends about 1100 V through the human body, resulting in an average current of 2.5 mA. From these numbers, estimate the electrical resistance of the human body.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)
