Answer:
Q=∆U+W
Explanation:
work done+ change in internal energy = heat supplied to change the internal energy
(1st law of thermodynamics)
Explanation:
Given that,
Radius R= 2.00
Charge = 6.88 μC
Inner radius = 4.00 cm
Outer radius = 5.00 cm
Charge = -2.96 μC
We need to calculate the electric field
Using formula of electric field

(a). For, r = 1.00 cm
Here, r<R
So, E = 0
The electric field does not exist inside the sphere.
(b). For, r = 3.00 cm
Here, r >R
The electric field is

Put the value into the formula


The electric field outside the solid conducting sphere and the direction is towards sphere.
(c). For, r = 4.50 cm
Here, r lies between R₁ and R₂.
So, E = 0
The electric field does not exist inside the conducting material
(d). For, r = 7.00 cm
The electric field is

Put the value into the formula


The electric field outside the solid conducting sphere and direction is away of solid sphere.
Hence, This is the required solution.
Answer:
A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.
Explanation:
A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.
White dwarfs are one of the densest elements in the universe, surpassed only by neutron stars and black holes. They can be considered as medium mass stars that fuses hydrogen into helium
A weally works when you pull something and a axle is something that you can push
Explanation:
I hope this helps
When current is increased, the the electromagnetic field gets more powerful.
