Which form of measurement used to measure brightness can be defined as the rate at which the star gives off energy?
The form of measurement that can be defined as the rate at which a star gives off energy is luminosity. Luminosity is measured in watts and indicates the total amount of energy emitted by a star per unit time.
When 10 electrons drop from fifth to second energy level?
When 10 electrons drop from the fifth to the second energy level, energy in the form of photons is emitted. The energy of the emitted photon is equal to the difference in energy levels between the initial and final states of the electrons. This process is known as photon emission or de-excitation.
What is the wavelength of the photon emitted when a hydrogen atom goes from the second energy level to the first energy level?
The wavelength of the photon emitted can be calculated using the Rydberg formula: 1/wavelength = R(1/n1^2 - 1/n2^2), where R is the Rydberg constant, n1 is the initial energy level (2 in this case), and n2 is the final energy level (1 in this case). Plugging in the values gives the wavelength of the photon emitted.
What is the main unit of measurement in the British system?
SECOND
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.

All of its output energy is absorbed in a detector that measures a total energy of 0.53 J over a period of 32 s How many photons per second are being emitted by the laser?
To calculate the number of photons per second emitted by the laser, we first need to find the power of the laser. Power is given by energy divided by time, so 0.53 J / 32 s = 0.01656 Watts. Next, we need to convert this power into the number of photons emitted per second using the relationship (E = n \cdot h \cdot f), where E is the energy of a single photon, n is the number of photons per second, h is Planck's constant, and f is the frequency of the photons emitted by the laser.

What is IPS in unit stand for?
IPS stands for "Inches Per Second" and is a unit of measurement used to express the speed or rate of something over time.
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
What is the English measurement of thermal energy?
Traditionally the BTU (British Thermal Unit), but now we usually use kilojoules
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
To find the number of photons being radiated per second, you need to calculate the energy of each photon first. Since the light bulb emits 100 watts (100 joules per second), and each photon has an energy of about 4.86 x 10^-19 joules for visible light, you can divide the total energy emitted per second by the energy of each photon to find the number of photons emitted.
Which combination of fundamental units can be used to express energy?
Energy can be expressed using the fundamental units of kilogram, meter, and second. This corresponds to the unit of energy, the joule (kg⋅m²/s²).
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.
What unit of time equals 9192631770 energy changes of a cesium atom?
The unit of time that equals 9,192,631,770 energy changes of a cesium atom is one second. This definition is the basis for the International System of Units (SI) second, which is defined using the frequency of radiation emitted by cesium-133 atoms.
