W = F D
W = ( F / A ) ( A D )
W = P ( AD )
W = P (V)
Work = area under the curve on a P-V diagram.

How it is possible to say that area under the curve on pv diagram gives magnitude of work done on a gas?
The following is just an informal discussion, to show why it is reasonable. Work = force x distance. Now, it requires a force to compress a gas. For simplicity, assume a piston of constant diameter. At higher pressures, the force required is greater. And a greater change in volume implies a larger distance.
What quantities are neither vectors nor scalars?
Electric Current is neither scalar nor vector , since in electric current in a wire has both magnitude and direction but there is no meaning of triangle rule there. Also, since it gives the magnitude of charge flowing per unit time, it has nothing to do with direction.
The difference between shear force diagram and shear force influence line diagram?
A shear force diagram is used to give the value of shear force at any point on the beam due to static load while the influence line gives the effect of a moving load at any point on the beam. Abdul Nafay Achakzai
Can the magnitude if the difference between two vectors ever be greater than the magnitude of their sum?
yes,if the components are making angle 0<=theta<=90 no ,the magnitude of vector can never attain a negative value |a|=square root of both components which always gives a positive value
Why do you use phasor Diagram?
phasor diagram is nothing but the vectorial representation of time-varying periodic signals(most common are sine and cosine) , whose magnitude is given by the amplitude of the signal and the direction (angle..) is given by the phase difference. this makes life a lot easier , calculations in vector-algebra domain is more easier when compared to trigonometric domain because here we can resolve any 'n' no. of vectors and by performing simple algebra of addition and subtraction gives us the desired result. Whereas in trigonometric domain we need to expansions like sin(A+B),cos(A-B) etc etc which is a laborious task

What do you multiply in a venn diagram to find the GCF?
You multiply all the numbers in the center of the Venn Diagram. This gives you the highest possible number that goes into both numbers.
Is the apparent magnitude of a star the amount of light is actually gives off?
No. It's what we see. (The amount it actually gives off is called the absolute magnitude.)
Which magnitude gives the most information about the physical nature of a star?
absolute bolometric magnitude
How are scalar and vector quantities similar?
Scalar and vector quantities give magnitude, and that makes them similar. The difference is that the vector quantity gives direction as well as magnitude. plz check out this for further details vHMnGsOrU5A
Name newtons law which gives magnitude of force?
2nd law of motion
What is a diagram and how is it used?
A diagram is a picture that goes with text and usually gives an example of what is in the text in picture form.
What is the actual amount of light a star gives off?
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
Does velocity ony desribe the direction un which an object is moving?
It gives the magnitude too
Geometrically the definite integral gives the area under the curve of the integrand Explain the corresponding interpretation for a line integral?
gemetrically the definite integral gives the area under the curve of the integrand. explain the corresponding interpretation for a line integral.
Why does the rightmost indifference curve give the highest number of utils?
It gives more satisfaction
Definition of integration?
geometically , the definite integral gives the area under the curve of the integrad .
