Answer:
a. 0.5x10⁵
Explanation:
The charge density = 10C/cm²
We are asked to find the magnitude of the electric flux density
The electric field of infinite sheet
E = σ/2Eo
We have electric density as follows:
D = EEo = EoE
Since charge density σ = 10C/cm²
σ = 10x10²C/m²
D = σ/2
10x10⁴/2
= 5x10⁴C/m²
= 0.5x10⁵C/m²
Therefore the magnitude is equal to 0.5x10⁵C/m². Which gives us option a as the answer
Answer:
False
Explanation:
According to the American National Standard for Engineering Drawings, there are ten (10) different types of lines used in engineering drawings to communicate important information about the item. Some of these lines could either be thick or thin. These include the following:
1. Visible Line
2. Hidden Line
3. Section Line
4. Center Line And Symmetry Line
5. Dimension Line Extension Line And Leader
6. Cutting-Plane Line Or Viewing-Plane Line
7. Break Line
8. Phantom Line
9. Stitch Line
10. Chain Line
Answer:
Gage pressure at the bottom of the tank = 46.1kP
Explanation:
Note that it is required to expressed the gage pressure ,pressure at the free surface=0 gage
Pressure due to the oil layer= (3m)*((800kg/m^3)(9.81m/s^2))/1000=25.9kpa
Pressure due to the brine layer=(2m)*((1030kg/m^3)(9.81m/s^2))/1000=20.2ka
Therefore, the pressure at the bottom=25.9+20.2=46.1kP
