Answer:
1.498 m
Explanation:
Electric potential due to a point charge V = K × Q / r
4.8 × 10 ⁴ V = 8.99 × 10⁹ N.m²/C² × 8 × 10⁻⁶ C / r
r = 8.99 × 10⁹ N.m²/C² × 8 × 10⁻⁶ C / 4.8 × 10 ⁴ V = 1.498 m
Answer:
a. WATER CONTENT.
mass of water (MW)= 417g - 225g
Mw= 192g
M= (Mw / Ms)
M= [192/417]
M= 0.46
M= 46.0%
b. Void Ration (e)
To calculate the void ratio we must first calculate the volume of solids. Then we can find the volume of voids by subtracting the volume of solids from the total volume.
Ps= (Ms/Vs)=GsPw
Therefore
Vs= (Ms/GsPw)
Vs= (417/ 2.70*1000)
Vs= 0.154cm3
But V= Vv+Vs
Vv=V-Vs
e= (Vv/Vs)
The correct answer is "immediately flood the area with water and clean the wound."
Further Explanation:
If someone is exposed to a potentially infectious material with a sharps item such a needle, they need to wash the area with clean water immediately. It must be a steady flow of water to get out any potential infectious material.
After flushing the injury with water, you will then wash the area or exposed skin with soap, if at all possible use a disinfectant on the area.
The person who was injured should seek medical assistance for tests to be sure that they have not been affected.
