What are the wavelengths of the two photons produced when a proton and antiproton at rest annhiilate (in meters)

Explanation:

mass of a proton = mass of an antiproton = 1.00727647 amu

total mass of proton and antiproton = 2.01455294 amu

1 amu = 931.5 x 10⁶ eV

2.01455294 amu = 1876.556064 x 10⁶ eV

Wavelength of radiation equivalent to this energy

=12375/1876.556064 x 10⁶ A = 6.5945 X 10⁻⁶A = 6.5945 X 10⁻¹⁶ m.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

it is b. absorbs thermal energy
