Answer:
82780.42123 m/s
14.45 days
Explanation:
m = Mass of the planet
M = Mass of the star =
r = Radius of orbit of planet =
v = Orbital speed
The kinetic and potential energy balance is given by
The orbital speed of the star is 82780.42123 m/s
The orbital period is given by
The orbital period is 14.45 days
The cost of electricity be $ 38.544.
<h3>What is electricity?</h3>
Electricity is the passage of charges in a conductor. From one end of the terminal to the other, charges are transmitted. Usually, the terminal moves from positive to negative. Since the nucleus holds the electrons loosely, they can move freely throughout the body.
Watts are units of power used to measure electrical output.
Price of electricity is $ 0.110 per kWh .
If a 40-W porch light on day and night for a year, total amount of electricity spend = power of the bulb × time
= 40 W × 1 year
= 40 W × 365 day
= 40 W × 365 ×24 h
= 350400 Wh
= 350.4 kWh.
Hence, the cost of electricity be = $350.4 × 0.110 = $ 38.544.

Answer:
= 591.45 T/s
Explanation:
i = induced current in the loop = 0.367 A
R = Resistance of the loop = 117 Ω
E = Induced voltage
Induced voltage is given as
E = i R
E = (0.367) (117)
E = 42.939 volts
= rate of change of magnetic field
A = area of loop = 7.26 x 10⁻² m²
Induced emf is given as
= 591.45 T/s
Answer:
undergoes a transition to a quantum state of lower energy
Explanation:
When electrons in an atom move to another quantum state, they emit/absorb a photon according to the following:
- If the electron is moving to a higher energy state, it absorbs a photon (because it needs energy to move to a higher energy level, so it must absorb the energy of the photon)
- if the electron is moving to a lower energy state, it emits a photon (because it releases the excess energy)
In particular, the energy of the absorbed/emitted photon is exactly equal to the difference in energy between the two levels of the electron transition:
