Answer:
Net charge contained in the cubeq= 3.536×10^-6C
Explanation:
Formular for total flux in a cube is given as:
Total flux= E300Acos(180) + E200Acos(0)
Where A is crossectional area
Total flux= A(E200-E300)
Total flux= q/Eo
q= Eo×total flux
q=(8.84×10^-12)×(100)^2×(100-60)
q= 3.536×10^-6C
Answer:
Part (i)
Z = 39.06 ohm
Part (ii)
R = 21.7 ohm
Explanation:
a) here we know that
maximum value of EMF = 125 V
maximum value of current = 3.20 A
now by ohm's law we can find the impedence as
now we will have
Part b)
Now we also know that
now we have
Answer:
45 takes less energy and is less stronger light than a 60 watt bulb, but a 60 watt bulb is stronger and takes more energy.
Explanation:
Bituminous coal
Explanation:
The most abundant type of coal in the United States is the bituminous coal. It accounts for about 45% of the total coal production in the United States
- Coal is one of the fossil fuels that is primary used for energy production.
- Some power plants are operated using coal as their fuel source.
- Coal produced in shallow swamps in which plant materials are suddenly buried in an environment that lacks oxygen.
- With burial and maturity, coal attains different levels.
It goes from Peat to Lignite to Sub-bituminous to Bituminous to Anthracite coal.

Answer:
Change in electric potential energy is -28.0 J
Explanation:
Electric potential energy is defined as the work is done to move a charge particle from one position to another in space in the presence of other charge particle or electric potential.
OR
Electric potential energy is also equal to the change in the configuration of the charge particles.
Thus,
Change in electric potential energy = - Work Done
According to the problem, Work Done is equal to 28 J. Thus,
Change in electric potential energy = -28 J
