Answer:he is incorrect
Explanation:he is wrong because if the sunlight is on the opposite side of the earth than the moon, then the sunlight would be blocked by the earth, making the moon dark, because the moon gets its light from the light that is reflected of the surface from the sun

Answer:
The volume of the balloon would be (580.12m) cm^3
Explanation:
From the ideal gas equation,
PV = nRT
P is pressure in the balloon = 742 mmHg = 742/760 = 0.976 atm
V is the volume of the balloon
n is the number of moles of carbon dioxide in the balloon. Let the mass of carbon dioxide be m.
n = mass/MW = m/44 = (0.023m) mol
R is gas constant = 82.057 cm^3.atm/mol.K
T is temperature of the balloon = 27 °C = 27 + 273 = 300 K
V = 0.023m × 82.057 × 300/0.976 = (580.12m) cm^3
Answer:
The answer is V = 0.9*C
Explanation:
from the relativity formula we have to:
Δt = γ * Δto
Clearing γ:
γ = Δt/Δto
Replacing values:
γ = 2070 s/900 s = 2.3
γ = 1/((1-(V/C)^2)^1/2)
1/((1-(V/C)^2)^1/2) = 2.3
1/(1-(V/C)^2) = 2.3^2
1/(1-(V/C)^2) = 5.29
Clearing V:
V = C * ((1 - (1/5.29))^1/2) = 0.9*C
