Answer:
77.625 cm
Explanation:
The given distance of the image behind the convex mirror, v = 11.5 cm
The focal length of the mirror, f = 13.5 cm
The mirror formula for convex mirror is given as follows;

Where;
u = The distance from the statue to the mirror
Therefore, we get;

Plugging in the values gives;

∴ The distance from the statue to the mirror, u = 621/8 cm = 77.625 cm.
I heard that the answer is convective zone, not sure if that’s right but i hope i helped :)
Answer:
D
Explanation:
the total speed and the total mass of the entire system remain the same weather one object is moving or stationary.
When two or more objects collide, the collision does not change the
total momentum of the two objects.
Whatever momentum is lost by one object in the collision is gained
by the other. The total momentum of the system is conserved.
