Answer:
= 0.086J
Explanation:
we are given three equal charges q₁ q₂ q₃ = 1.60 μC
sides of triangle = 0.800m
U = 1/4πε₀(3q²/r)
1/4πε₀ = 9.0 × 10⁹ N.m²/C²
U = 9.0 × 10⁹ ((3 * 1.60 × 10⁻⁶)² / (0.800))
= 0.086J
Answer:
Explanation:
Let magnetic force F acts towards right and the string makes an angle of θ with the vertical in equilibrium .Let T be tension in equilibrium
T cos θ = mg
T sin θ = F
Dividing
Tan θ = F / mg
F = mg Tanθ
= 51.5 x 9.8 x 10⁻³ x 26 / 20.8 Tanθ = 26 / 20.8 )
= 630.875 X 10⁻³ N
Answer:
mechanical thermal chemical
Explanation: because you use mechanical energy to turn it on
According to the Law of Conservation of Charge, the net
charge remains constant. If both things have different charges, upon contact,
they would share the charge equally. In this case, the total charge is -16μC.
The final charge for each ball would be -8 μC.
The car's (average) acceleration would be

The car's position over time would be given by

so that after 2.4 seconds, the car will have traveled a distance of
