Δt=
This because ε = dΦ/dt, and emf is a voltage so it can also be written as dΦ/dt = IR
Because ΔΦ= ABcosθ for each of the N loops and cosθ is just 1 here only A needs to be replaced, and it can be replaced with A=πr^2, which makes that part of the equation ΔΦ_m=N*B0*πa^2
Explanation:
Ionic crystals
1. They are formed by electrostatic attraction between the cation and anion.
2. Naturally solid and brittle in nature.
3.Generally good conductors of electricity in moltane state and have high melting and boiling points.
Example: NH4Cl is an inonic compound with NH4^+ being cation and Cl- being anion.
Molecular Solid
1. These are formed by sharing of electrons pair between the atoms. A shared pair of e- is called a covalent bond.
2. Usually not a good conductor of electricity even in melted state.
3. They mostly liquids and gases only a few are solids.
examples , CO, CO2 , H2CO3 , etc.

Answer:
The answer to your question is Pressure = 3.55 atm
Explanation:
Data
R = 0.082 atm L/mol°K
mass = 4.5 g
volume = 2 L
temperature = 35°C
Pressure = ?
Process
1.- Calculate the moles of Methane
molar weight = 12 + 4 = 16 g
16 g of Methane --------------- 1 mol
4.5 g --------------- x
x = (4.5 x 1)/16
x = 0.281 moles
2.- Convert temperature to Kelvin
°K = 273 + 35
= 308
3.- Use the ideal gas law to solve this problem
PV = nRT
- Solve for P
P = nRT / V
- Substitution
P = (0.281)(0.082)(308) / 2
- Simplification
P = 7.097 / 2
- Result
P = 3.55 atm
