The answer is abbe’s resolution limit in which RL is equals to 0.612 the wavelength divided by NA. This is the minimum distance between objects when you can still see them as separate objects. In addition, the shorter the wavelength is better and the larger numerical aperture is better. <span />
Answer:
b. Passive reference configuration implies that the reference direction of the current is the same direction as the reference direction of the voltage.
Explanation:
Term Passive reference configuration implies that current i flowing through the element voltage across which is v.
P= v×i
we say that power is absorbed or released by an element depends upon the sign of P. And This depends upon the sign of current entering and the voltage across the terminal. This is know as passive reference configuration.
If the current enters the negative end of polarity the power P= -v×i
therefore here option B is the correct answer.
Answer:
Height covered after crossing window top = 0.75 m
Explanation:
In the question,
The height of the window pane = 1.8 m
Time for which the flowerpot is in view = 0.66 s
So,
The time for which it was in view while going up is = 0.33 s
Time for which it was in view while going down = 0.33 s
So,
Let us say,
The initial velocity of the flowerpot = u m/s
So,
Using the equation of the motion,
So,
Velocity at the top of the window pane is given by,
Now,
Let us say the height to which the flowerpot goes after crossing the window pane is = h
So,
Using the equation of motion,
Therefore, the height covered by the flowerpot after window is = 0.75 m
