Answer:
Gamma Rays
Explanation:
Because it has the most energetic radiation and could penetrate through six feet of concrete. It is so strong it can damage your dna.
Answer:
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. The wavelength decreases as the light enters the medium and the light wave changes direction.

Answer:
Req = 50 Ω
Explanation:
The equivalent resistance is basically the sum of all the resistances in a circuit.
The sum of these resistances will depend whether these resistance are in series or parallel.
If the resistances are on series, the expression to use is:
R = R₁ + R₂ + R₃ + .......Rₙ (1)
If the resistances are on parallel then the expression to use is:
1/R = 1/R₁ + 1/R₂ + ........1/Rₙ (2)
Now, according to the picture, we have R₁ and R₄ in series, so here we have to use (1):
R₁₄ = 10 + 30 = 40 Ω
R₂ and R₃ are in parallel so we use (2):
1/R₂₃ = 1/20 + 1/20 = 2/20 = 1/10
R₂₃ = 10 Ω
Finally, R₁₄ and R₂₃ are in series (Because of the sum of the resistance in each side, they are now forming one resistance in each side), therefore, we use (1) again to get the equivalent resistance of the whole circuit:
Req = 10 + 40

Req = 50 Ω</h2>
Hope this helps
It is TRUE. The pivot point of a lever is called the fulcrum .
