Answer:
Energy of ultra violet photons < Energy of radio waves
Wavelength of ultra violet photons > Wavelength of radio waves
Explanation:
The increasing order of the wavelength is given by
Gamma rays
x rays
Ultra violet rays
Visible radiations
Infrared rays
micro waves
Radio waves
So, ultra violet rays has larger wavelength than radio waves.
As we know that the energy is inversely proportional to the wavelength.
So, the energy of radio waves is more than the energy of ultra violet waves.
Energy of ultra violet photons < Energy of radio waves
Wavelength of ultra violet photons > Wavelength of radio waves
The rod transferred negatively charged particle to the metal sphere. The rod becomes less negatively charged than it was originally (originally it was charged to -21 nc, now it has -8, and -8>-21), so it must have moved 13 nc of negative charge to the sphere.
Answer:
.864 M
Explanation:
For first order decomposition,
rate constant k = 1/t x ln a / (a - x )
given , a = 1.33 M , t = 644 s , k = 6.7 x 10⁻⁴ , a - x = ? = b( let )
6.7 x 10 ⁻⁴ = 1/644 x ln 1.33/b
ln 1.33/b = 6.7 x 10⁻⁴ x 644 = .4315
1.33 / b = e⁰ ⁴³¹⁵ = 1.5395
b = 1.33 / 1.5395 = .864 M.
