The intensity level from a set of quintuplets (five babies) : 56 dB
Wave intensity is the power of a wave that is moved through a plane of one unit that is perpendicular to the direction of the wave
Can be formulated
I = intensity, W m⁻²
P = power, watt
A = area, m²
The farther the distance from the sound source, the smaller the intensity
So the intensity is inversely proportional to the square of the distance from the source
Intensity level (LI) can be formulated
Io = 10⁻¹²
For the level of intensity of several sound sources as many as n pieces can be formulated:
The intensity level of 1 baby is
LI = 10 log 8.10⁴
LI = 49
The intensity level of 5 babies :
LI5 = LI + 10 log n
LI5 = 49 + 10 log 5
LI5 = 49 + 7
LI5 = 56
The intensity of a laser beam
There might be a problem of a lot of power being dissipated if too many
appliances are turned on at once.
We can infer from Ohm's law that as resistance decreases, the total current increases.
The power dissipated through the circuit is directly proportional to the square
of the current.
We can therefore state that the power dissipated via heat will be much when
too many appliances are turned on at once.

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.
"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.
"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.
