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
Answer:
I = 12 A
Explanation:
For this exercise we use the relationship that voltage is proportional to the product of current and resistance
V = I R
I = V / R
let's calculate
I = 120/10
I = 12 A
We have that the Average Force is given
Avg F=2.0488N

Answer:
If you are asking the definition here is your answer:--
Explanation:
<u><em>Electrons</em></u> are negatively charged particles that revolve around the nucleus of an atom. In QFT(Quantum field theory) Electrons are vibration of space in the positive energy field.
<u><em>Protons </em></u> are positively charged particles found in the nucleus of an atom held by the strong nuclear force. In QFT(Quantum field theory) protons are also different type of vibration in space in the direction of positive energy field.
The Specific Heat Capacity of the liquid is 43.846 KJ/(Kg K).
- It is given that Mass of liquid (M) = 0.0012Kg, Initial temperature (T1) = 23°C, Final temperature (T2) = 62°C, Voltage (V) = 8v, Current (I) = 0.95A, Time (t) = 270s
- The quantity of heat that must be applied to an object in order to cause a unit change in temperature is known as the heat capacity or thermal capacity of that object.
- We know that heat capacity for a substance is :
- H = m*C*ΔT - equation (1)
- When a conductor is subjected to current flow, the conductor's free electrons are set in motion and collide with one another. Moving electrons experience kinetic energy loss and partial thermal energy conversion as a result of the collision. This impact of current is referred to as its heating effect.
- Due to electric current, heat energy is :
- H = Power * Time
- H = Current * Voltage * Time
- H = I*V*t - equation (2)
- Using equation (1) and (2),
- m*C*ΔT = I*V*t
- Substituting the values for m, ΔT, I, V and t.
- 0.0012Kg * C * (62 - 23)K = 0.95A * 8v * 270s
- Solving for C, we get C = 43.846 KJ/(Kg K)
