Given :
The focal length of a concave mirror is 18 cm.
To Find :
The radius of curvature of the concave mirror.
Solution :
We know,
Therefore, the radius of curvature of concave mirror is 36 cm.
Hence, this is the required solution.

Answer:19.32 m/s
Explanation:
Given
initial speed of car(u)=4.92 m/s
acceleration(a)=
Speed of car after 4.5 s
using equation of motion
v=u+at
v=19.32 m/s
Displacement of the car after 4.5 s
s=54.54 m
The gravitational force between two masses is given by the formula
where G is the <em>gravitational constant, </em>M is the larger mass, m is the smaller mass, and r is the distance between the centers of the objects. The values we can change here to affect that gravitational force are the <em>mass </em>and the <em>distance</em>. Time and shape have no impact on this force.
