Direction. Velocity is a vector that describes both speed and direction, while speed is a scalar that describes only speed regardless of direction.
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
I think its B but it could also be D because usually they say line up and than u do the activity or strech so..
Plz mark as brainlist hope i helped
Answer:
20 m/s
Explanation:
The acceleration of an object determines the increase in velocity per second.
In this case the acceleration is 20m/s^2.
That is, the increase is 20m/s each second.
I hope this is useful for you
Regards
