What is the wavelength of the photon emitted when a hydrogen atom goes from the second energy level to the first energy level?
121
When 10 electrons drop from fifth to second energy level?
Only one photon is produced per electron in any de-excitation. The number of energy levels it drops only determines the energy of the photon emitted.
Which form of measurement used to measure brightness can be defined as the rate at which the star gives off energy?
Luminosity is defined as the rate at which a star gives off energy. Luminosity can be measured in joules per second or watts.
What is the relation between 1 kilowatt hour and joules?
The joule is the SI unit of measurement for energyor work, whereas the watt is the SI unit of measurement for power.Work is defined as the process of converting one form of energy into another, e.g. work is done when an electric motor converts electrical energy into kinetic energy.Power is defined as the rate of doing work, so a watt is equivalent to a joule per second.
What is the main unit of measurement in the British system?
SECOND
What is the wavelength of the photon emitted when a hydrogen atom goes from the second energy level to the first energy level?
121
What does a stars luminosity measure?
Luminosity is the total amount of energy emitted by a star per second.

Only one photon is produced per electron in any de-excitation. The number of energy levels it drops only determines the energy of the photon emitted.
What is the measurement in time for 4 kilowatts?
"kilowatts" is a rate, not a time. A kilowatt is 1000 watts, or energy being transferred at 1000 joules per second. (A watt is a joule per second.) Your question means the same as this question: "What is the measurement in time for 100 forty-watt lightbulbs?" You can leave the lights on as long as you wish. Collectively, every second they will convert 4000 joules of electrical energy to light and heat energy.
Galileo's measurement in meters per second?
The measurement was 5000 metres per second
Why does the sun provide heat energy?
The energy emitted form the Sun is generated in the core of the Sun, where Hydrogen is being fused into Helium. This process involves the conversion of 400 tons of mass into energy every second and E=MC2 means that there is alot of energy produced and this makes the Sun hot.
How Wm-2 is the unit of energy?
Hello W/m2 is not the unit of energy. Students get confused usually as we use the symbol E for the energy radiated per unit area per second. So it is not only the energy. It is the energy emitted in one second. So J/s which equals to W. Per unit area needs /m2 So W/m2 is not the unit for energy. Only J ie joule is the unit of energy.
When 60 W means that W joules of energy are transferred into the bulb each second. In use how much energy is given out by the bulb each second?
The light bulb will use electrical energy at the rate of 60 W (60 J/s), and it will emit that energy, also at the rate of 60 W.Note that in any real light bulb, only part of the energy is emitted as visible light. The remainder is mainly heat.
What is the sis?
It is the abbreviation of the International Standard of measurement units. Meter for length, kg for mass, Joule for energy, second for time, .....etc
Frequency is a measurement of what pass per second?
Frequency is a measurement of how many cycles, or wave crests, there are per second. It is measured in Hertz, equal to cycles/second.Frequency is a measurement of how many cycles, or wave crests, there are per second.

State the units of measurement for mechanical energy and electrical power?
The official unit for any type of energy (not just mechanical energy) is the joule. The official unit for any power (not just electrical power) is the watt, equal to joules / second.
Which form of measurement used to measure brightness can be defined as the rate at which the star gives off energy?
Luminosity is defined as the rate at which a star gives off energy. Luminosity can be measured in joules per second or watts.
