No they don't. Incident rays parallel to the axis of a concave mirror
reflect from the mirror's surface and converge at its focal point.
<span>Here, g is the acceleration due to gravity at the Earth's surface and is the standard gravity, defined as 9.8m/s....So, the force by that gravity is called g-force.....</span>
Decibels I believe? I’m not 100% sure
The answer to your problem is I believe (B.)
We have that the magnification of each focal length is given respectively as
A) has 
B) has 
C) has 
From the question we are told that:
Focal Length F
Generally, the equation for Magnification is mathematically given by

Therefore

For A

Therefore


Therefore

For B

Therefore

Where


Therefore

For C

Therefore

Therefore


Therefore

Conclusion
From the calculations above we can rightly say that the magnifications of the values above are
A has 
B has 
C has
