Answer:
through nuclear fusion
Explanation:
The burning of the sun is not chemical combustion. It is nuclear fusion. This combustion releases energy which we experience as the heat and light given off by the flame.
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W.
Answer:
Explanation:
Path difference for the destructive interference of a single slit:
For the first - order minimum, n = 1, and
.........(1)
For the second - order minimum, n = 2, and
.........(2)
Dividing equation (2) by equation (1):
Answer:
- The x-component of the velocity of the third particle is
- The y-component of the velocity of the third particle is
- The increase in kinetic energy is
Explanation:
We can take conservation of linear momentum to find the velocities:
The initial momentum of the nucleus will be:
as is at rest.
After the decay, the first particle has a momentum
the second one has a momentum
By conservation of linear momentum we have:
for the third particle, we know that mass is conserved:
The velocity will be:
The kinetic energy is given by
And, as the initial kinetic energy is zero, this must be the increase in energy.
