I believe you're talking about displacement. It's a directional vector that depicts the movement of a point between two instances.
<u>Answer:</u> The correct answer is Option b.
<u>Explanation:</u>
Young's Modulus is defined as the ratio of stress acting on a substance to the amount of strain produced.
Stress is defined as force per unit area and strain is defined as proportional deformation in a material.
The equation representing Young's Modulus is:
where,
Y = Young's Modulus
F = force exerted by the weight
l = length of wire
A = area of cross section
= change in length
Hence, the correct answer is Option b.
Work is force times distance. If there's no distance, there's no work being done.
Which of these is an example of convection?
<u>
A. an egg boiling in water
</u>
B. an egg frying in a pan
C. an egg exposed to a flame
D. an egg warming under a light
1. New moon
This is because the moon comes between the Earth and sun and this is only possible during its new moon phase.
2. Full moon
This is because the Earth comes between the Moon and the sun and the effect is only visible when there is a full moon.
3. Corona
The corona is the outer layer and is the only one visible when there is an eclipse.
