Answer:
Option C
Explanation:
Diverging lens are negative lens as they have negative focal length. Their
magnification is smaller than one.
They produce virtual image in which the refracted rays extended back in order to meet
Hence, option C is correct
Hi! I believe the correct answer is A. Do you have any other questions I can help you with? I would be glad too.

Answer:
When elements bond together or when bonds of compounds are broken and form a new substance
Explanation:
the Axis Perpendicular to the Length and Passing through the Center. Take a uniform thin rod AB whose mass is M and length is l. YY’ axis passes through the center of the rod and perpendicular to the length of the rod. We have to calculate the moment of inertia about this axis. YY’.
Suppose, small piece dx is at a distance x from the YY' axis. Hence, mass of length dx is =(
l
M
)dx The moment of inertia of small piece about the YY' axis
dl=[(

)dx]x

Therefore, the moment of inertia of the complete rod about the YY' axis.
b) Moment of Inertia about the axis perpendicular to the the length and passing through the Corner If I
