Answer:
C. 
Explanation:
0 charge → <em>Neutron</em>
1 charge → <em>Proton</em>
I am joyous to assist you anytime.
W boson has +1e or - 1e charge, Z boson has 0 charge.
Leptons have +1e, -1e or 0 charge.
Photons have 0 charge.
Only quarks have a charge of +2/3e or -1/3e of an electron charge.
To be exact, only up-type quarks (Up, Down and Top quarks) have a +2/3e or two thirds of an electron charge.
So the correct answer is D) Quark.
Gravitational force = G · (mass₁) · (mass₂) / (distance)
(distance²) = G · (mass₁) · (mass₂) / (Gravitational force)
G = 6.67 x 10⁻¹¹ n-m² / kg² (the "gravitational constant")
Distance² = (6.67 x 10⁻¹¹ n-m² / kg²) (28,500 kg) (2.2 x 10⁸ kg) / (39 N)
Distance² = (6.67 · 28,500 · 2.2 x 10⁻³ N-m²) / (39N)
Distance² = (418.209 N-m²) / (39N)
Distance² = 10.72 m²
<em>Distance = 3.275 meters</em>
An absurd scenario, but that's by golly what the math says with the numbers provided. I guess it's a teeny tiny planet orbiting 3.275 meters outside a teeny tiny black hole.
It’s none of those because it’s moving at a constant rate
Answer:
Spontaneous emission is a quantum effect, which in a semiclassical picture can be described as an emission which is stimulated by vacuum noise.
