Answer:
The forces of push and pull
Explanation:
In the egg drop experiment, the egg is balanced on top of a toilet paper tube and balanced on a pan. The pan itself is placed on top of a glass of water. When the experimenter uses his hands to push the pan, the force of gravity pulls the egg downwards making it move down, right into the glass of water.
So the two forces which are applied in opposite directions are;
1. The force of push applied horizontally by the hand when it pushes the pan away, and
2. The force of pull caused by gravity which makes the egg move vertically downwards.
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.
