what is the energy of a photon that has a frequency of 5.0x1014 Hz?
A photon with a frequency of 5 THz has an energy of 20.678 meV.
3.98 x 10 ^ -21 J ΰΌβ§βΛβ§ apx ! :))
Energy = Planck's constant * Frequency so, basically 5.5 X 10^-18 J = 6.626 X 10^-34 J*s/Frequency = 8.3 X 10^15 Hertz ( or s^-1 )
The question doesn't inform us as to what units are associated with the wavelength 5 x 10-7, whether we're talking sound or electromagnetic, and if sound, what the transmission medium is.So the only possible response is:The frequency is (speed in same units as wavelength per second) divided by (5 x 10-7)
This short period is 5x10^(-9) seconds.
5x10=50 50x15=750 750x5=3750 ...3750
weight refers to the gravitational force. The force of gravity on a 5kg mass will be 5kgwt or 5x10 Newtons. F = m x g Newtons in SI units - Newtonβs second law g is acceleration due to gravity on earth. g can be taken as 9.8 m/s*2 or 10 for easy calculation. 50 Newtons is weight of a 5 kg mass. If you like physics and math and wish to clear doubts watch my videos @PhysicsFusion-sm3rt hope this helps!

5x10 = 50 - 4 = 46 Answer - 46
The answer to that equation is 47.
50
It is 50000000.
-50
5x10-3 = 0.005 5x10-2 = 0.05 5x10-1 = 0.5 5x100 = 5 5x101 = 50 5x102 = 500 5x103 = 5000 ...
The answer to that equation is 47.
0.0005
50000000
5x10=50
50000000000
