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
If the intelligent aliens on that distant planet could receive our signal, and then reply to us INSTANTLY with no delay, then our Scientists on Earth would hear the response <em>eight years after</em> they sent their original greeting.
Light and radio waves both travel through space at the same speed. If our scientists sent a radio transmission to that distant planet, it would take four years for the radio message to get there and be heard. Any response would take four years to travel back to us. If the aliens didn't dilly-dally and sent their response immediately, the round trip would total up to eight years.
Newton’s 3rd law of motion
Answer:
A force that pushes or pulls is known as Newton's third law of Motion.
Explanation:
Newton's Third Law of Motion. Newton's Third Law of Motion states that for each action, there's an equal and opposite reaction. What this suggests is that pushing on an object causes that object to keep off against you, the precise same amount, but within the other way.
