Effieciency of a machine is never 100%

1 answer:

4 0

Answer:

in real life yes it's true because of energy lost in another way that we do not want. like car engine lost some energy as heat. So the energy from gasoline can't converted 100% to move the tire. Maybe it only 40-60 % energy use for move and the rest lost as heat and other

but sometime it can be 100% of efficiency on physics text book so that we can learn physics in the easiest way.

What is the electrical force between q2 and q3? Recall that k = 8. 99 × 109 N•meters squared over Coulombs squared. 1. 0 × 1011

Force on the particle is defined as the application of the force field of one particle on another particle. the electrical force between q₁ and q₃ will be –1. 1 × 10¹¹ N.

<h3>What is electric force?</h3>

Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.

The electric force in the second case will be the same as in the first case. Therefore the force on the particle will be the same.

$\rm F= K\frac{q_2q_3}{r^2}$
