Answer:
(I). The store energy is 0.432 J.
(II). The energy density is 687.54 J/m³.
Explanation:
Given that,
Voltage = 12.0 V
Capacitor = 6.00 mf
Radius = 0.1 m
Distance = 10 mm
(I). We need to calculate the energy store
Using formula of store energy
Where, C = capacitor
V = voltage
Put the value into the formula
(II). We need to calculate the energy density
Using formula of energy density
Where, r = radius
d = distance
Put the value into the formula
Hence, (I). The store energy is 0.432 J.
(II). The energy density is 687.54 J/m³.
Answer:
What constant velocity means
Explanation:
To have a constant velocity, an object must have a constant speed in a constant direction
<h2>Answer</h2>
1 V = 1 kg m2 s−² C
1 V = 1 kg m2 s−³ A−1
(one kilogram meter squared per second cubed per ampere)
<h2>Explanation</h2>
<em>The work required to move an electric charge of one coulomb through an electrical potential difference of one volt,</em>
<h2> Volts = Joules / Coulombs</h2><h2 />
Joules = Newton x metre
Volts = Nm / coulombs
Newton = kg x metre / second ²
Volts = kg x metre / second ² coulombs
Volt in terms of meters (m), seconds (s), kilograms (kg), and coulombs (c)
<h3>For further:</h3>
Coulomb = Amp * second
Volts = kg x metre / second ³ Amp
