Answer:If an object's speed changes, or if it changes the direction it's moving in,
then there must be forces acting on it. There is no other way for any of
these things to happen.
Once in a while, there may be a group of forces (two or more) acting on
an object, and the group of forces may turn out to be "balanced". When
that happens, the object's speed will remain constant, and ... if the speed
is not zero ... it will continue moving in a straight line. In that case, it's not
possible to tell by looking at it whether there are any forces acting on it
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.
