(1) <span>Electric current is defined as the rate of </span>charge<span> flow past a given point in an electric circuit. It is measured in Coulombs/second, also called Amperes. In </span>DC electric circuits<span>, it can be assumed that the </span>resistance<span> to current flow is a constant so that the current in the circuit is related to </span>voltage<span> and resistance by </span>Ohm's law, which is:
<span>
V = I*R
Where V = Voltage
I = Current
R = Resistance

(4) <span>Renewable energy is the energy which is generated from the natural sources i.e. sun, tides, wind etc. Examples are: Solar Energy, Wind energy( windmill) etc. for electricity generation.
Advantages of Renewable Energy:
1) It is available in abundant quantity.
2) It is free to use.
3) It has </span><span>low carbon emissions, therefore it is considered as green and environment friendly.
Disadvantages of Renewable Energy:
1) It is not easy to setup plants and machinery for renewable energy.
2) Initial costs for setting up those plants and machinery is quite high.
3) The energy from the natural sources is not available 24/7. In Solar energy case, energy </span><span>can be used during the day time and not during night or rainy season etc.
</span>
Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity. Sources may be <span>fossil fuels, natural gas, oil and coal etc.
</span><span>Advantages of Non-Renewable Energy Sources:
1) They are easy to use.
2) They are cheap.
Disadvantages:
</span>1) They will expire some day (as they are limited).
2) The speed at which such resources are being used can have serious environmental changes.
3) They release toxic gases in the air when burnt which are the major cause for global warming.
<span>4) Since these sources are going to expire soon, prices of these sources are proliferating day by day.

Answer:
Ф,
Ф
Explanation:
Now find the components NxNxN_x and NyNyN_y of N⃗ N→N_vec in the tilted coordinate system of Part B. Express your answer in terms of the length of the vector NNN and the angle θθtheta, with the components separated by a comma.
Vectors are quantities that have both magnitude and direction while scalar quantities have only magnitude but no direction.
This a vector quantity
from the diagram the horizontal component of the length of the vector will be
Ф
the vertical component will be
Ф
this is in the opposite direction because the x can be extrapolated to the negative axis
