The magnification <u>is 31.16.</u>
Magnification is the process of increasing the apparent size of something rather than its physical size. This increase is quantified by a calculated number, also called the "factor". If this number is less than 1, it means size reduction, sometimes called size reduction or reduction.
u = -19.3
f = -18.7 cm.
m = f/f-u
= -18.7/-18.7 +19.3
<u>= 31.16</u>
The term magnification refers to the size of the image produced by the lens compared to the size of the object. For lenses: Magnification "m" is the ratio of image height to object height. The magnification of a lens is defined as the ratio of image height to object height. It is also given by image distance and object distance. equal to the ratio of image distance to object distance.

Answer:
C. Mass
Explanation:
The extensive property is that property of material that depends upon the amount of matter (mass) of substance. Thus, in the given options only, mass is the extensive property. All the other properties other than mass are independent of mass.
The simple method to find out the extensive property is to divide the substance into half. If that property for both individual halves also becomes half, then it is dependent on mass and an extensive property. If the property remains same as before for each half, then it is independent of mass and called intensive property such as, density, temperature, pressure, etc.
Thus the correct answer is <u>C. mass</u>
It would be option A (a decrease in mass with an increase in volume)

Answer:
The velocity of the other fragment immediately following the explosion is v .
Explanation:
Given :
Mass of original shell , m .
Velocity of shell , + v .
Now , the particle explodes into two half parts , i.e 
.
Since , no eternal force is applied in the particle .
Therefore , its momentum will be conserved .
So , Final momentum = Initial momentum
The velocity of the other fragment immediately following the explosion is v .
