Answer:
The force applied is 32 N
Explanation:
F = ma
F = 8 × 4
F = 32 N
Answer:
Yeah ice floats on water.
Observation
Example in those areas were ice is found like Antarctica ice is found on top of water.
Answer:
you need at least two out of the three to get any aenser

Answer: a.The mirrors and eyepiece of a large telescope are spring-loaded to allow them to return quickly to a known position. </h2>
Explanation:
Adaptive optics is a method used in several astronomical observatories to counteract in real time the effects of the Earth's atmosphere on the formation of astronomical images.
This is done through the insertion into the optical path of the telescope of sophisticated deformable mirrors supported by a set of computationally controlled actuators. Thus obtaining clear images despite the effects of atmospheric turbulence that cause the unwanted distortion.
It should be noted that with this technique it is also necessary to have a moderately bright reference star that is very close to the object to be observed and studied. However, it is not always possible to find such stars, so a powerful laser beam is used to point towards the Earth's upper atmosphere and create artificial stars.
I would use miles
Because miles will give you less of an answer
