The term that is being described by the definition given above is called PEER REVIEW. What is done in the peer review is that, the experiment is being evaluated or checked first by people who are also working on the same field. So the answer for this is option C.
Answer:
Because the ball is dropped, we are going to assume its initial velocity is 0. With that said, acceleration is essentially the change in the velocity versus the change in time, hence the unit m/s^2, which can be thought of as “meters per second per second.” The only force acting on the ball is gravity.
That being said, you can simply divide the change in velocity by the change in time, giving you an answer of 9.8 m/s^2, which is the value of g. Even if they did not give you a time, the answer would still always be the value of g (that is if the question pertains to earth), as acceleration due to gravity is a constant.

at any angle between -90 and 90 degrees. In the diffused reflection ,the surface is rough and the direction of light in not the same as the incident light. It can be reflected at any angle
Answer: Statement 1 is incorrect.
Reason:
Unit of measure of angular distance is not meters.
Explanation:
The term 'angular size' is used to describe the apparent size of the objects in the night sky.
The angular distance is defined as the angle through which an object moves on a circular path. The SI unit is radian.
Other units are revolution (rev) and degrees.
In statement 1, angular distance is measured in meters which is incorrect. In other options, there is no factual mistake so they are correct.
Let's discuss them,
Statement 2:
Here, we are talking about the use of outstretched hand to estimate the angular distances and sizes which is correct.
Statement 3:
This statement talks about the same angular sizes of the sun and the moon, here the term is again used correctly.
Statement 4:
Here, the angular distance is measured in the correct units i.e, degrees so this statement is also correct.
