Coefficient of volume expansion is 8.1 ×10⁻⁴ C⁻¹.
<u>Explanation:</u>
The volume expansion of a liquid is given by ΔV,
ΔV = α V₀ ΔT
ΔT = change in temperature = 48.5° C
α = coefficient of volume expansion =?
V₀ = initial volume = 2.35 m³
We need to find α , by plugin the given values in the equation and by rearranging the equation as,

= 8.1 ×10⁻⁴ C⁻¹.
Answer:
Meter marks are on cut-off portion of stick is 100 - 60 = 40 m
Explanation:
Given data:
Spaceship length of L = 100 m
Relative velocity between the ship and stick is given as

The observed length observed by the outside observer is

putting all value to get observe length
put

L' = 60 m
Meter marks are on cut-off portion of stick is 100 - 60 = 40 m
B because those are all symptoms
The length of the potatoes is (0.4) x (the length of the pan).
The width of the potatoes is (0.2) x (the width of the pan).
