(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.
3/10 is greater than 4/17. 3/10 = 3/10 * 17/17 = 51/170 4/17 = 4/17 * 10/10 = 40/170 thus 3/10 > 4/17.
