Answer with explanation:
The Vertices of Triangle QRS , is not given.
Coordinates of vertices of Preimage, will be Positive,that is, (x,y),x→Positive, y→Positive
while coordinates of vertices of Image will be Negative that is
x→Negative, y→Negative.
≡If we Rotate the Triangle QRS, which is in Quadrant I ,whatever the coordinates of it's vertices be, if rotated ,either in, 180°, Clockwise or Anticlockwise Direction, it will be in Quadrant III.
⇒Option C
→→ Quadrant III

Answer:
The distance between the astronomers and the moon was meters.
Step-by-step explanation:
We have that the speed is the distance divided by the time, so:
In this problem, we have that:
The reflected laser beam was observed by the astronomers 2.52 s after the laser pulse was sent. This means that .
If the speed of light is 3.00 times 10^8 m/s, what was the distance between the astronomers and the moon?
We have that m/s.
We have to find d. So:
The distance between the astronomers and the moon was meters.
