Answer grilling a burger :
Explanation:
Correct Answer: B optionPotential Difference = V = 200 V
Charge on the plate = Q =
![5.0*10^{-9}](https://tex.z-dn.net/?f=5.0%2A10%5E%7B-9%7D%20)
C
Capacitance = C
Q, C and V for a parallel plate capacitor are related as:
Q = CV
⇒
C = Q/V
Using the values in the formula, we get:
![C= \frac{5*10^{-9} }{200}=2.5*10^{-11}](https://tex.z-dn.net/?f=C%3D%20%5Cfrac%7B5%2A10%5E%7B-9%7D%20%7D%7B200%7D%3D2.5%2A10%5E%7B-11%7D%20%20)
F
Therefore, B option is the correct answer.
Answer:
![D = 3.55 \times 10^6 m](https://tex.z-dn.net/?f=D%20%3D%203.55%20%5Ctimes%2010%5E6%20m)
Explanation:
Light rays coming from moon is blocked by the pencil
so as per figure we know that angle subtended by pencil and angle subtended by moon must be same
so we have
![Angle = \frac{Arc}{Radius}](https://tex.z-dn.net/?f=Angle%20%3D%20%5Cfrac%7BArc%7D%7BRadius%7D)
so we have
![\frac{D}{3.8 \times 10^8 m} = \frac{0.7 cm}{75 cm}](https://tex.z-dn.net/?f=%5Cfrac%7BD%7D%7B3.8%20%5Ctimes%2010%5E8%20m%7D%20%3D%20%5Cfrac%7B0.7%20cm%7D%7B75%20cm%7D)
so we have
![D = 3.55 \times 10^6 m](https://tex.z-dn.net/?f=D%20%3D%203.55%20%5Ctimes%2010%5E6%20m)
