Answer:
10250 N/C leftwards
Explanation:
QA = 4 micro Coulomb
QB = - 5 micro Coulomb
AP = 6 m
BP = 2 m
A is origin, B is at 4 m and P is at 6 m .
The electric field due to charge QA at P is EA rightwards
![E_{A}=\frac{KQ_{A}}{AP^{2}}=\frac{9\times10^{9}\times4\times10^{-6}}{6^{2}}=1000 N/C (rightwards)](https://tex.z-dn.net/?f=E_%7BA%7D%3D%5Cfrac%7BKQ_%7BA%7D%7D%7BAP%5E%7B2%7D%7D%3D%5Cfrac%7B9%5Ctimes10%5E%7B9%7D%5Ctimes4%5Ctimes10%5E%7B-6%7D%7D%7B6%5E%7B2%7D%7D%3D1000%20N%2FC%20%28rightwards%29)
The electric field due to charge QB at P is EB leftwards
![E_{B}=\frac{KQ_{B}}{BP^{2}}=\frac{9\times10^{9}\times5\times10^{-6}}{2^{2}}=11250 N/C (leftwards)](https://tex.z-dn.net/?f=E_%7BB%7D%3D%5Cfrac%7BKQ_%7BB%7D%7D%7BBP%5E%7B2%7D%7D%3D%5Cfrac%7B9%5Ctimes10%5E%7B9%7D%5Ctimes5%5Ctimes10%5E%7B-6%7D%7D%7B2%5E%7B2%7D%7D%3D11250%20N%2FC%20%28leftwards%29)
The resultant electric field at P due the charges is given by
E = EB - EA
E = 11250 - 1000 = 10250 N/C leftwards

Answer:
waves
Explanation:
There are three major ways in which heat or thermal energy is transferred namely: conduction, convection and radiation. Please find the description of each below;
- Conduction is the method of heat transfer which involves a physical contact between the substances involved.
- Convection, on the contrary, occurs via a liquid medium
- RADIATION is a method of heat transfer which involves neither physical contact or liquid medium (matter) but occurs through WAVES e.g electromagnetic waves. For example, the sun transfers heat to the Earth via RADIATION.
Answer:
d. 5 ohms
Explanation:
For resistors in parallel, the equivalent resistance is found with:
1/Req = ∑(1/R)
1/R = 1/15 + 1/15 + 1/15
1/R = 3/15
R = 15/3
R = 5
Answer:
Velocity is the rate of change of displacement.
