What is a capacitor and capacitance.​

Physics
1 answer:
inessss [21]3 years ago
4 0

Answer: A capacitor is is device which stores electrical energy in an electrical field. The capacitance is the capacity of the capacitor to store charge in it. Two conductors are separated by an insinuator (dielectric) and when an electric field is applied, electrical energy is stored in it as charge.

There are two unitless vectors:
Hunter-Best [27]

Answer:

200.38^0

Explanation:

Given the forces:

F1 = 8.92 i + 17.37 j

F2 = 8.31 i - 10.97 j

If a third vector is added to them such that they add up to to the null vector as F1 + F2 + F3 = 0

then to get F3:

F3 = -F2-F1

F3 = -(8.31 i - 10.97 j)-(8.92 i + 17.37 j )

F3 = -8.31 i + 10.97 j-8.92 i - 17.37 j

F3 = -8.31i-8.92i+10.97j-17.37j

F3 = -17.23i-6.4j

from the vector:

x = -17.23 and y = -6.4

angle of the third vector with respect to the +x-axis is expressed as:

\theta = tan^{-1}\frac{y}{x}\\ \theta = tan^{-1}\frac{-6.4}{-17.23}\\\theta = tan^{-1}0.3715\\\theta = 20.38^0

Hence the angle the vector makes with the x axis will be \theta = 180+20.38 = 200.38^0

Given that the efficiency of heating your room is roughly 35%, what mass of natural gas is actually necessary to heat your room
Mrac [35]

Answer:

Mass of natural gas needed to heat the room is 350,000BTUs

Explanation:

The heating efficiency of a furnace is never 100% because not all energy is released and not all heat is available to heat the place. A lesser efficiency requires more consumption of fuel. Heating values are used for heating fuels in order to calculate the mass of fuel needed.

The heating value of natural gas is 1,000,000BTUs

Therefore the formular for calculating mass of natural gas needed= Heating value of natural gas×efficiency.

Mass=1,000,000×0.35

Mass=350,000BTUs

a ball on a string makes 30.0 revolutions in 14.4s, in a circle of radius 0.340m. what is its period.(unit=s)
STALIN [3.7K]

Answer:

0.480 seconds

Explanation:

The period is the time for 1 revolution.  Writing a proportion:

14.4 s / 30.0 rev = t / 1 rev

t = 0.480 s

The period is 0.480 seconds.
