(17-4)+10=23 13+10=23
a - 3 + 17 = 10 Therefore, a - 3 = -7 a = -4
8/17 ÷ 4/5 = 40/68 which can be simplfied to 10/17.
40 x 170 = 4 x 10 x 17 x 10 which equals 4 x 17 x 10 x 10 which becomes 4 x 17 x 100 = 68 x 100 = 6800 Or, you can multiply 4x17, then put two zeroes on the end.

The wavelength is w = hc/E = .2E-24/4E-17 = 5E-9 meters.
The frequency of the photon can be calculated using the equation: frequency = speed of light / wavelength. Given that the speed of light is approximately 3 x 10^8 m/s, the frequency for a microwave photon with a wavelength of 10^-4 m would be approximately 3 x 10^12 Hz.
The frequency of a photon is given by the equation f = c/λ, where c is the speed of light (3 x 10^8 m/s) and λ is the wavelength of the photon. Plugging in the values, we find that the frequency of a photon with a wavelength of 4.5 x 10^-4 m is approximately 6.67 x 10^14 Hz.
The frequency of a photon can be calculated using the equation: frequency = speed of light / wavelength. Plugging in the speed of light (3 x 10^8 m/s) and the given wavelength (4.5 x 10^-4 m) gives a frequency of 6.67 x 10^14 Hz.
To determine the frequency of a photon, you can use the equation E = hf, where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 Js), and f is the frequency. If the wavelength of the photon is given, you can use the equation c = λf, where c is the speed of light (3.00 x 10^8 m/s), λ is the wavelength, and f is the frequency.
The wavelength of the photon can be calculated using the Rydberg formula: 1/λ = R(1/4^2 - 1/n^2), where R is the Rydberg constant. Substituting n=4, the calculation gives a wavelength of approximately 97.2 nm.
Frequency = speed/wavelength = 299,792,458/4.5 x 10-4 = 666.21 GHz . (rounded)

To calculate the number of moles of photons needed, first convert the energy to joules (1 kJ = 1000 J). Then use the energy of a single photon formula (E = hc/λ) to calculate the energy of one photon. Finally, divide the total energy needed by the energy of one photon to find the number of photons, and then convert it to moles.
The energy of a photon can be calculated using the formula E = hf, where h is Planck's constant (6.626 x 10^-34 J·s) and f is the frequency of the photon. Plugging in the values, the energy of a photon with a frequency of 4 x 10^7 Hz is approximately 2.65 x 10^-26 Joules.
