Answer:
Final velocity, V = 11.5m/s
Explanation:
Given the following data;
Initial velocity, U = 2.5m/s
Acceleration, a = 1.5m/s²
Time, t = 6secs
To find the final velocity, we would use the first equation of motion
V = U + at
Substituting into the equation, we have
V = 2.5 + 1.5*6
V = 2.5 + 9
Final velocity, V = 11.5m/s
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
