Last One.... If Im not Wrong!
Burning of Fossil Fuels, Increase the CO2 And therefore the Green Effect!!
Answer:
Exposure time limitation, shielding and distance.
Explanation:
- Limitation of exposure time, since the dose received is directly proportional to the exposure time, so that, at a shorter time, lower dose. For this reason, planning is suggested, to reduce time.
-
Use of shields. This allows a reduction in the dose received by the technician when filtered by the barrier (screen). There are two types of shields or screens, the primary barriers (attenuate the radiation of the primary beam) and the secondary barriers (avoid diffuse radiation).
-
Distance to the radioactive source. The dose received is inversely proportional to the square of the distance to the radioactive source. Therefore, if the distance is doubled, the dose received will decrease by a quarter. Reason for this, it is advisable to use devices or remote controls whenever possible.
Answer:
= 0.0298V
Explanation:
Electric field between two conductor = σ / ε₀
σ = 33pC/m²
= 33 × 10⁻¹²C/m²
ε₀ = 8.85 × 10 ⁻¹²C²/Nm²
E = 33 × 10⁻¹² / 8.85 × 10 ⁻¹²
= 3.7288N/C
potential difference between two conductors = Ed
where d = 8mm = 8 × 10 ⁻³m
V = 3.7288 × 8 × 10 ⁻³
= 29.83 × 10 ⁻³
= 0.0298V
Current can vary in different branches of a circuit
