Electric field due to a point charge is given as
here we know that
also the distance is given as
now we will have
so we will have
so above is the electric field due to proton
Answer:
b) The star is moving away from us.
Explanation:
If an object moves toward us, the light waves it emits are compressed - the wavelength of the light will be shorter, making the light bluer. On the other hand, if an object moves away from us, the light waves are stretched, making it redder. If from laboratory measurements we know that a specific hydrogen spectral line appears at the wavelength of 121.6 nanometers (nm) and the spectrum of a particular star shows the same hydrogen line appearing at the wavelength of 121.8 nm, we can conclude that the star is moving away from npos, since the wavelength related to that star is more expanded.
Answer:
Explanation:
Same numbers of protons but different number of neutron so i would go for A same atomic number different number of neutrons
Answer:
2.25 Ω
Explanation:
Standard equation
V = IR re-arrange to
V /I = R then sub in the values given
9 / 4 = 2.25 Ω
