Two aluminized optical flats 15 cm in diameter are separated by a gap of 0.04 mm, forming a capacitor. what is the capacitance in picofarads
Answers
Answer: 3978 pF
Explanation:
Capacitance can be defined as ability to store charge. It is the ratio of charge over electric potential.
where, A is the area of the plates and d is the distance between plates forming the capacitor.
diameter of the plates, di = 15 cm =0.15 m
radius of the plate, r = di/2 = 0.075 m
Area of the plates, A = πr² = 0.018 m²
Distance between the plates, d = 0.04 mm = 0.00004 m
Permittivity, ∈₀ = 8.84 × 10⁻¹² F/m
Capacitance,

Among the option given below, the most appropriate SI base unit for measuring mass is Gram. Thus, the correct option is B.
What is an SI unit?
An SI unit may be defined as a form of the metric system that is utilized universally as a standard for measurements. It is an international system of units. The expanded form of the SI unit is Systeme International.
The exact SI base unit for measuring mass is the kilogram, kg. But it is not mentioned in the options. So, the most appropriate SI base unit for measuring mass is Gram.
Ampere is the SI base unit for measuring the electric current. A Meter (m) is the SI base unit for measuring length. A Pound is the international standard symbol used as a unit of mass and i.e. lb.
Therefore, among the option given below, the most appropriate SI base unit for measuring mass is Gram. Thus, the correct option is B.

At first glance, this statement seems to be true. But after about a
microsecond of further consideration, one realizes that the statement
would actually set Boyle spinning in his grave, and is false.
Boyle's law states that there is a firm relationship among the pressure,
temperature, and volume of an ideal gas, and that you can't say anything
about how any two of these quantities depend on each other, unless you
also say what's happening to the third one at the same time.
As the pressure of an ideal gas increases, the volume will decrease in
direct proportion to the volume, IF THE TEMPERATURE OF THE GAS
REMAINS CONSTANT.
If you wanted to, you could increase the pressure AND the volume of an
ideal gas both at the same time. You would just need to warm it enough
while you squeeze it.
