umka2103 [35]

Answer:

Calculate 'R' of convex mirror and height of the real image

the radius of the convex mirror is 48cm

Explanation:

Distance between convex and concave mirror is =60cm

Radius of the concave mirror (R) = 200cm

For the concave mirror, u = ∞

V = {R}/{2}=100cm

The object for the convex mirror and the final image is on the pole of the concave mirror, and distance between convex and concave mirror is 60cm

u_1=60-100 =-40cm

Object will be behind the convex mirror

1/f=1/40+1/60  

f=24cms

the radius of the convex mirror is 48cm

Andru [333]

Explanation :

It is given that, a heavy box is in the back of a truck and the truck is accelerating to the right.

The description is shown in<em> figure 1</em>. Here, the forces that act on both box and the truck are the normal force, the frictional force and their weight mg.

The free body diagram is shown in <em>figure 2</em>. This shows the total forces            ( F = ma )acting on the truck. As a result, the truck will move in a forward direction.

Hence, this is the required explanation.
