Answer:
Ohm’s Law states that current is proportional to voltage; circuits are ohmic if they obey the relation V=IR.

Answer:
The wind speed of the plane in still air is 50m/h
Explanation:
Let p = plane speed in the air
Let w = wind speed.
since , we can;
(Eqn1) can be simplified further into
In (Eqn2), multiply both sides with the reciprocal of which gives us
So we have;
p - w = 150
p + w = 250
2p = 400
p = 200
Put p (200) into p - w = 150;
200 - w = 150
w = 50
Therefore,
The speed of the plane in still air is 200m/h,
The wind speed is 50m/h.

Explanation:
I do indeed have the answer but rather than explaining it you should go out and find the answer perhaps by attention
1) I am pretty sure that f the following alternative energy sources which is NOT inexhaustible is <span>D.Wind Energy. I choose this option because this type of energy can not be used completely or in full measure.
2) </span><span>The problems which are associated with the increased use of nuclear energy are being revealed by all the options attached to this question. As you can see, all the issues connected to increacing of nuclear energy are represented above the question, so the answer is D.
3) </span>One problem with wind energy as a major source of electricity is D. the expense of large tracts of land in populated areas. This is the major drawback of such source of renewable energy.
