The convex spherical mirror is the diverging mirror. The image distance is 20.4 cm. The magnification is 0.417. The image is virtual and upright.
<h3>What is magnification?</h3>Magnification is the ratio of image distance to the object distance.
Object distance is 49 cm and the focal length of convex mirror is 35 cm, then image distance is calculated by the lens maker formula.
1/f = 1/v +1/u
1/-35 = 1`/v +1/49
v= -20.4 cm
Thus, the image distance is 20.4 cm.
The magnification is given by
m = v/u
m = -20.4 / 49
m = 0.417
Thus, the magnification is 0.417.
The image formed is by virtual meeting of light rays and above the principle axis. Thus the image is virtual and upright.

Answer:d
Explanation:
Given
Magnitude of Vector A is 3 m
and Magnitude of vector B is 4 m
So the maximum value of resultant can be 7 m when both are at an angle of
and its minimum value can be 1 m when both are at angle of
So the resultant must lie between 1 m to 7 m
Answer:C
Explanation:
Given
mass is at
mark
mass is at
mark
Scale is Pivoted at
For scale to be in equilibrium net torque must be equal to zero
Taking ACW as positive thus
Therefore a net torque of 0.04 g is required in CW sense which a mass can provide at a distance of
from pivot
therefore in meter stick it is at a distance of
