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.
Answer:
Explanation:
As we know that
also we know that
it is given as
also we can find the magnitude of two vectors as

Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels
You will use the equation for work which is w= F times distance so you will take 40N times 36N which equals 1440N
