The magnitude of your displacement can be equal to the distance you covered, or it can be less than the distance you covered. But it can never be greater than the distance you covered.
This is because displacement is a straight line, whereas distance can be a straight line, a squiggly line, a zig-zag line, a line with loops in it, a line with a bunch of back-and-forths in it, or any other kind of line.
The straight line is always the shortest path between two points.
Thermal- transfer of heat thru space
Radiation- the average amount of energy of motion in the molecules of a substance
Thermometer- a thin glass tube with a bulb on one end that contains a liquid, usually mercury or colored alcohol

Answer: See explanation
Explanation:
Gravity is simply referred to as the force of attraction between two particles or masses. Through gravity, the moon moves round the Earth.
Gravity also causes a fruit to fall from its tree. It can also cause an object to roll and fall from the table to the ground. In gravity, distance and mass are vital.
Answer:
(d) 44.8°
Explanation:
For refraction,
Using Snell's law as:
Where,
Θ₁ is the angle of incidence
Θ₂ is the angle of refraction
n₁ is the refractive index of air which is 1
n₂ is the refractive index of water which is 4/3
Given that angle of incidence = 70°
So,
<u>Angle of refraction = sin⁻¹ 0.7048 = 44.8°.</u>
