Answer:
53 minutes
Explanation:
To solve this problem, we need to use common proportions to convert.
= 11.7km * 1mi/1.61km * 1hr/8.2mi * 60min/hr
≈ 53 minutes

Answer: 0.8 nC
Explanation: In order to explain this problem we have top use the expression for the capacitor of parallel plates, which is given by:
C=εo*A/d where A and d are the area and the separation of the plates.
Then we have
V=Q/C so ΔV= Q* Δd/(εo*A)
Q= 100* 0.054*8.85*10^-12/( 0.06)=0.8 nC
Answer: 1.8 g
Explanation:
We start first, by calculating the amount of Helium
n = m/M
m = mass of Helium
M = molar mass if Helium
n = 2/4 = 0.5 moles
proceeding further, we use ideal gas law. PV = nRT
Then we have
P1V1/n1T1 = P2V2/n2T2
So that,
n2 = n1T1P2V2/P1V1T2
From the question, we know that, P1 = P2, and T1 = T2. So that,
n2 = n1v2/v1
n2 = (0.5 * 3.9) / 2
n2 = 1.95/2
n2 = 0.975 moles. With this, we can determine the mass, m2 of Helium
n = m/M
m = n * M
m = 0.975 * 3.9
m = 3.8
The difference between both masses are 3.8 - 2 = 1.8 g
Thus, 1.8 g of Helium was added to the cylinder
