Answer:
Dose = 5.4 10⁻⁴ Sv
Explanation:
The radiation dose absorbed by the body is 81% of the incident radiation, which is the number of particles per energy of each particle
E = 0.81 n₀ E₀
E = 0.81 4.2 10⁹ 0.81 6.1 10⁻¹³
E = 2.075 10⁻³ J
Effective radiation dose
Dose1 = n x RBE
Dose1 = 2,075 10⁻³ 15
Dose1 = 3.1 10⁻² REM
The effective radiation dose in sievert
Dose = dose1 / m
Dose = 3.1 10⁻² / 57
Dose = 5.4 10⁻⁴ [j / kg]
Dose = 5.4 10⁻⁴ Sv
Answer:
Mass
Explanation:
The total sum of atoms in an object is the mass of the object. There are several ways to quantify the number of atoms in a substance.
- In chemical calculations, the number of moles is a good representation of the number of atoms contained in a body.
- Mass is the amount of substances a body has.
- If we can sum up all the atoms in a substance, one will arrive at the mass of the substance
Answer:
x = 600 Km
Explanation:
given,
speed of transverse wave = 4.05 Km/s
speed of longitudinal wave = 7.695 Km/s
difference of the time of arrival of wave = 69.9 s
now,
t₂ - t₁ = 69.9 s
let x be the distance
x = 597.645 Km
x = 600 Km
distance of recorder from the site is 600 Km approximately.
