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
We divide the thin rectangular sheet in small parts of height b and length dr. All these sheets are parallel to b. The infinitesimal moment of inertia of one of these small parts is
where
Now we find the moment of inertia by integrating from
to
The moment of inertia is
(from (-a/2) to
(a/2))
Answer:
Total energy=Kinetic energy+Potential energy
Explanation:
the total energy will be obtained from the energy of an object in motion and the energy stored in the object
The main function of the cardiovascular system is therefore to maintain blood flow to all parts of the body, to allow it to survive. Veins deliver used blood from the body back to the heart.
