Anon‐conducting spherical shell, with an inner radius of 4.0 cm and an outer radius of 6.0 cm, has charge spread non‐uniformly through its volume between its inner and outer surfaces. the volume charge density ρ is the charge per unit volume, with the unit coulomb per cubic meter. for this shell ρ = b/r, where r is the distance in meters from the center of the shell and b = 3.0 μc/m2. what is the net charge in the shell?

0.19 m/s and 0.45 m/s

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
