The world energy consumption was about 6*10^22 J. How much area must a parallel plate capacitor need to store this energy Assume
Nastasia [14]

Answer:

A = 5 \times 10^{32} m^2

Explanation:

As we know that the energy stored in the capacitor is given as

Q = \frac{1}{2}CV^2

here we know that

Q = 6 \times 10^{22} J

also we know that

V = 5 Volts

now we have

6 \times 10^{22} = \frac{1}{2}C(5^2)

C = 4.8 \times 10^{21} F

now we know the formula of capacitance

C = \frac{\epsilon_0 A}{d}

4.8 \times 10^{21} = \frac{(8.85 \times 10^{-12})(A)}{1}

A = 5 \times 10^{32} m^2

the velocity of an object is given v(t), and the acceleration is given by a(t). what is the relationship between the total
zmey [24]

The rate at which velocity changes is called acceleration. (Attensity exists when velocity varies.) If a moving object changes speed.

Why does time accelerate the rate at which velocity changes?

A motion's acceleration is the rate at which it changes from one velocity to another. A velocity's rate of change with respect to time is referred to as its acceleration. The amount and direction of acceleration are both properties of a vector quantity.

A change in velocity is known as what?

A velocity change's acceleration is measured. Acceleration is the measure of how quickly a velocity changes with time. The acceleration measure used in SI is M/s2.

27 degrees to kelvin, 20 dg to milligrams, and 3 to decimeters.
Gala2k [10]
K = C + 273, so 27°C = 27+273 = 300 K

1 dg = 100 mg, so 20 dg = 20×100 = 2,000 mg
