An advantage of using coal power over solar power to generate electricity is Reliable Fuel.
Compared to solar power or wind energy, coal is a reliable, predictable, and dependable fuel. While it may not be at the forefront of national energy production, it can provide invaluable backup service and highly reliable fuel.
What is coal power ?
"Coal-fired power plants burn coal to make steam and the steam turns turbines (machines for generating rotary mechanical power) to generate electricity." Many industries and businesses have their own power plants, and some use coal to generate electricity for their own use and mostly in combined heat and power plants.
What is solar power ?
"Solar power works by converting energy from the sun into power." There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from residential rooftops to 'solar farms' stretching over acres of rural land.

the answer is A. for me
Period, T = 1/f --- Where T = period (s), and f = frequency (Hz).
Substituting by use of the values of frequency given in the current scenario,
T = 1/440 = 2.27*10^-3 seconds
Answer:
fewer number of loops in the secondary coil.
Explanation:
The transformer equation states that:
where
Vp is the voltage in the primary coil
Np is the number of loops in the primary coil
Vs is the emf induced in the secondary coil
Ns is the number of loops in the secondary coil
Solving the expression for Vs,
Therefore, we see that in order to reduce the emf in the secondary coil, we can reduce Ns, the number of loops in the secondary coil. So the correct option is
fewer number of loops in the secondary coil.
The correct choice is
B. sublimation, then condensation
Sublimation is the name of the process where a solid directly converts into gas on heating. on heating solid crystals of iodine directly change into gas. hence this is sublimation.
condensation is the process where gas is converted into liquid on cooling.
here iodine gas is being converted into droplets on reducing the temperature. hence this is condensation.
