Explanation:
bad weather usually form when low pressure pushed high pressure ot the way.
Answer:
The attached system shows that there’s an integrator between the point where disturbance enters the system and error measuring element. A any time when R(s)=0 then
and considering that
then
For ramp disturbance d(t)=at
therefore, the steady state error is given by
Whenever
has a double intergrator, the error
becomes zero
Answer:
• Corona discharge means <u> </u><u>neutralization</u><u> </u><u>of</u><u> </u><u>charge</u><u> </u><u>action</u><u> </u><u>at</u><u> </u><u>a</u><u> </u><u>sharp</u><u> </u><u>point</u>
example; a pear shaped conductor, lightening conductor, van de graaf generator.
Explanation:
• In corona discharge, When a sharp conductor is placed somewhere in open space. The charges of opposite chrage attract the opposite ions in the air around that conductor.
• This increases the charge density and electric field intensity at the sharp point, this neutralises the charge at sharp point hence a discharge known as corona discharge occurs.

My best guess is b but I honestly don’t know
