The average speed is 615.7 mph (275.2 m/s)
Explanation:
The average speed of an object gives a measure of how fast an object is moving over a certain time interval. It is a scalar quantity, and it is calculated as follows
where
v is the average speed
d is the distance covered
t is the time interval
For the jet in this problem, we have:
d = 1293 mi is the distance covered
t = 2.1 h is the time interval
Therefore, the average speed is:
We can also convert into SI units (m/s), keeping in mind that:
And so

Answer: I'm pretty sure that this one's just an opinion but I guess 3 meters so you have a chance to notice it and move or 1 meter so that it doesn't hit as hard when it lands.
Answer:
radio telescope, because it captures radio waves from space
Explanation:
The technology the scientists used to capture the image is likely to be a radio telescope. This telescope is able to produce images from electrical signals transmitted by the radio waves the trail of the asteroid generates.
- Telescope are used to study very far and distant bodies.
- So, due to their special design, it is the best instrument to use for this kind of study.
- The radio telescope picks radio waves produced from astronomical bodies in space.
Sound waves.
Sound waves are not electromagnetic radiation. Every other option is an electromagnetic radiation.
No because the top has more oxygen to it which will break the particles up and have them freeze easier.
so if something froze at the bottom of the lake it would float to the top and that's why water always freezes from the top down :))
