Question

Якою була маса тіла, якщо при опроміненні з енергією 1кДж воно отримало поглинену дозу 10 Гр?​

Answer 1

Ответ:

100 кг

Объяснение:

D=W/m

1 кДж = 1000 Дж

10 = 1000/m

10m = 1000

m = 100

Answer 2

Mass of the Body After Absorbing Radiation Energy

The mass of the body after absorbing radiation energy can be calculated using the Einstein's mass-energy equivalence formula, which states that the change in mass is directly related to the change in energy.

The formula for calculating the change in mass is: Δm = ΔE / c^2

Where: - Δm = change in mass - ΔE = change in energy - c = speed of light in a vacuum (approximately 3.00 x 10^8 m/s)

Given: - ΔE = 1 kJ = 1 x 10^3 J - ΔD = 10 Gy = 10 J/kg

Calculating the change in mass: Δm = (1 x 10^3 J) / (3.00 x 10^8 m/s)^2

Δm = (1 x 10^3 J) / (9.00 x 10^16 m^2/s^2)

Δm ≈ 1.11 x 10^-14 kg

Therefore, the mass of the body after absorbing radiation energy of 1 kJ with a absorbed dose of 10 Gy would increase by approximately 1.11 x 10^-14 kg.
