Answer:
Explanation:
The speed of light is 3.0 x 10⁸ m/s
We need to find the distance traveled by it in one day.
1 day = 24 hours
1 day = 24 × 3600 seconds
= 86400 s
Now, using the formula of speed to find the distance covered as follows :
Putting all the values, we get :
Hence, light will cover of distance in one day.
Answer:
P_2 = 62.69 psi
Explanation:
given,
P₁ = 70 psia T₁ = 55° F = (55 + 459.67) R
P₂ = ? T₂ = 115° F = (115 + 459.67) R
we know,
p = ρ RT
ρ is the density which is constant
R is also constant
now,
P_2 = 62.69 psi
Hence, the increase in Pressure is equal to P_2 = 62.69 psi
