Last One.... If Im not Wrong!
Burning of Fossil Fuels, Increase the CO2 And therefore the Green Effect!!
Answer:
E = 1440 kJ
Explanation:
It is given that,
Power of a cooker oven is 800 W
Voltage at which it is operated is 230 V
Time, t = 30 minutes = 1800 seconds
We need to find the electrical energy used by the cooker oven. The product of power and time is equal to the energy consumed. So,
So, electrical energy of 1440 kJ is consumed by the cooker oven.
I’m assuming it’s A earth.
The energy of the red light emitted by a neon atom is 2.827*10^-19J
Light produces photons which might be small packets of power. as the atoms of an object are heated, it results within the manufacturing of photons. The electrons locate pleasure from the warmth and produce extra energy. This power emits inside the shape of a photon, and extra photons are released because the cloth becomes hotter.
The SI unit of wavelength is metre typically denoted as m. at the same time as measuring wavelength the multiples or fractions of a metre is also used. extensively, exponential powers of 10 are used while wavelengths are of a huge property. while there are shorter wavelengths they're expressed as negative exponential.
c=3*10^8 h=6.626*10^-34
wavelength= 703.2*10^-9m
E=2.827*10^-19J
Hence energy of the red light is 2.827*10^-19J.
