Answer:
Energy of scattered photon is 232.27 keV.
Kinetic energy of recoil electron is 497.73 keV.
The recoil angle of electron is 13.40°
Explanation:
The energy of scattered photon is given by the relation :
.....(1)
Here E₁ is the energy of incident photon, E₂ is the energy of scattered photon, is mass of electron and θ is scattered angle.
Substitute 730 keV for E₁, 511 keV for and 120° for θ in equation (1).
E₂ = 232.27 keV
Kinetic energy of recoil electron is given by the relation :
K.E. = E₁ - E₂ = (730 - 232.27 ) keV = 497.73 keV
The recoil angle of electron is given by :
Substitute the suitable values in above equation.
= 13.40°
Both balls land at the same time. If there is no air resistance they will both accelerate at the same rate and hit the ground at the same time with the same speed.
A). Earth completes one rotation on its rotation axis
every (3 minutes and 56 seconds less than 24 hours).
This causes night and day. It's rotation, not precession.
B). Earth completes one orbital revolution around the sun
every (365 plus a little bit) days. It's revolution, not precession.
C). I'm not sure what happens on a cycle of 512 years.
It may have something to do with the moon. But whatever
it is, it's not precession.
D). When you spin a top and it starts to run down, the first
thing that happens is that the handle of the top, or the point
on top of the top, starts moving in a circle. That's precession.
That's what the Earth's axis is doing. The north pole points
toward the north star (Polaris) now. But the north pole is
actually drawing out a big circle in the sky, and other stars
will become the "north star" far in the future.
The north pole draws out a full circle in the sky, roughly
once every 26,000 years. That's precession.
Its called condensation. condensation is <span>water that collects as droplets on a cold surface when humid air is in contact with it. aka. clouds</span>
A: Renewable resources make cleaner energy.
D: It often costs more to produce energy from renewable resources.
E: More local suppliers can provide energy from renewable resources to customers
Explanation:
Renewable sources of energy are cleaner and more accessible source of energy. They are easily replenished.
With current usage metrics, they can satisfactorily meet the energy demand of the world without affecting their supply.
- Renewable energy include biomass, wind energy, wave energy, solar energy e.t.c
- These energy sources are easily replenished.
- To produce energy from renewable sources, it usually costs more.
- Most equipment and devices that produces energy from renewable sources are highly pricey.
- Renewable energy is the future of energy production.
- Most smart cities around the world have solely relied on harnessing this source of energy.
- They no carbon emission to the environment and would not lead to climate change.
