During electrical storms if you are driving a car, it is best to stay inside the car as its metal body acts as a Faraday cage with zero electrical field inside. If in the vicinity of a lightning strike, its effect is felt on the outside of the car and the inside is unaffected, provided you remain totally inside. This is also true if an active (“hot”) electrical wire was broken (in a storm or an accident) and fell on your car.

An electric field due to a positively charged spherical conductor is shown above. Where will the electric field be weakest?
Suppose that the electric field experienced due to a positively charged small spherical conductor at a certain distance is
E . What will be the percentage change in electric field experienced at thrice the distance if the charge on the conductor is doubled?
The classic Millikan oil drop experiment setup is shown above. In this experiment oil drops are suspended in a vertical electric field against the gravitational force to measure their charge. If the mass of a negatively charged drop suspended in an electric field of 1.18×10
−4 N/C strength is 3.85×10
−21 g, find the number of excess electrons in the drop.
A conductor allows free charges to move about within it.
The electrical forces around a conductor will cause free charges to move around inside the conductor until static equilibrium is reached.
Any excess charge will collect along the surface of a conductor.
Conductors with sharp corners or points will collect more charge at those points.
A lightning rod is a conductor with sharply pointed ends that collect excess charge on the building caused by an electrical storm and allow it to dissipate back into the air.
Electrical storms result when the electrical field of Earth's surface in certain locations becomes more strongly charged, due to changes in the insulating effect of the air.
A Faraday cage acts like a shield around an object, preventing electric charge from penetrating inside.
is it possible to leave every good at the same level
Joseph
I don't think so. because check it, if the demand for chicken increases, people will no longer consume fish like they used to causing a fall in the demand for fish

is not really possible to let the value of a goods to be same at the same time.....

Suppose the inflation rate is 6%, does it mean that all the goods you purchase will cost
6% more than previous year? Provide with reasoning.
Not necessarily. To measure the inflation rate economists normally use an averaged price index of a basket of certain goods. So if you purchase goods included in the basket, you will notice that you pay 6% more, otherwise not necessarily.
Good day
How do I calculate this question: C= 100+5yd G= 2000 T= 2000 I(planned)=200.
Suppose the actual output is 3000. What is the level of planned expenditures at this level of output?

money as unit of account means what?
Kalombe
A unit of account is something that can be used to value goods and services and make calculations

all of you please speak in English I can't understand you're language

I want to know how can we define macroeconomics in one line
Muhammad
it must be .9 or 0.9
no Mpc is greater than 1
Y=100+.9Y+50
Y-.9Y=150
0.1Y/0.1=150/0.1
Y=1500

hi can someone help me on this question
If a negative shocks shifts the IS curve to the left, what type of policy do you suggest so as to stabilize the level of output?
discuss your answer using appropriate graph.
