1 answer:
Answer:
Focal length, f = 10 cm
Explanation:
We have,
A concave mirror forms a real image at 15.0 cm from the mirror surface along the principal axis, it means that the image distance is 15 cm
The object is placed at a distance of 30 cm, u = -30 cm
It is required to find the focal length of the mirror. Let it is f. Using mirror's formula to find it:
So, the focal length of the mirror is 10 cm.

Explanation:
To solve this problem we must understand that the weight of anybody is defined as the product of mass by gravitational acceleration. Gravitational acceleration depends on the place in space where a certain body is located.
where:
W = weight [N]
m = mass = 100 [g] = 0.1 [kg]
g = gravity acceleration [m/s²] or [N/kg]
