Ahydrogen-1 atom in the ground state absorbs a uv photon. as a result, the 1h atom is ionized – it breaks into a proton moving with a speed of 1.15×103 m/s and an electron moving with a speed of 2.11×106 m/s in the opposite direction. calculate the wavelength of the uv photon. [note: masses of electron and proton are available in the textbook and on the internet; use masses in kg.]

Explanation:

Here we can use momentum conservation to find the initial wavelength of UV photon

so the equation for momentum conservation is given as

we will have

so we will have

i would think it's food chain

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
