To answer this item, we assume that the gas being referred to here is an ideal gas such that it follows the Gay-Lussac's law wherein,
P = kT
The equation shows the direct relationship between the pressure and the temperature. Thus, if heat is added which would consequently raise the substance's temperature, will also increase the pressure.
Solids don't change their shape, and gases have no fixed volume. So the answer must be the LIQUID phase.
Answer: Magnitude of the force exerted on the egg by the ground is 9.2N
Explanation:
Given the following :
Mass of egg (m) = 150g = 0.15kg
Height(h) from which egg is dropped = 3m
velocity of egg before hitting the ground (u) = 4.4m/s
Final velocity of egg (V) = 0
Time taken (t) = 0.072s
Magnitude of the force exerted on the egg by the ground can be found by applying Newton's 2nd law:
Momentum = mass × velocity
From Newton's second law:
Force = mass × change in Velocity with time ;
That is
F = m * ΔV / t
Inputting our values
F = 0.15 * (4.4 - 0) / 0.072
F = 0.15 × (4.4 / 0.072)
F = 0.15 × 61.11
F = 9.16N
F = 9.2N
