<u>Given:</u>
EMF = 0.88 V
Strength of magnetic field, B = 0.075 N/A-m
Velocity, v = 4.20 m/s
<u>To determine:</u>
The length of wire, L
<u>Explanation:</u>
The EMF is related to strength of the magnetic field B as:
EMF = L*B*v
L = EMF/B*v = 0.88/0.075*4.20 = 2.79 m
Ans: The length of the wire is around 2.8 m
Answer:
n = 2 mol
Explanation:
Given data:
Number of moles of water vapors = ?
Volume of water vapors = 44.8 L
Temperature = 273 K
Pressure = 1 atm
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
by putting values,
1 atm × 44.8 L = n×0.0821 atm.L/ mol.K × 273 K
44.8 L. atm = n×22.4 atm.L/ mol
n = 44.8 L. atm /22.4 atm.L/ mol
n = 2 mol
