My opinion is that energy is not something that's made just like u feed ur self and u have energy u have to feed the earth and it will survive
Answer:
The charge on the ball bearing 4.507 × 10^-8 C
Explanation:
From Coulomb's law
F = kq1q2/r²
make q2 the subject
q2 = Fr²/kq1
q2 = (1.8×10^-2 × 0.026²) ÷ (9×10^9 × 30×10^-9)
q2 = 4.507 × 10^-8 C
<span>The factors that are used to determine power are:
Voltage,current and the power factor.
</span><span>Power = Voltage x Current x K
Watts = Volts x Amps x Power Factor</span>
