A small convex mirror is placed 60 cm from the pole and on the axis of a large concave mirror of radius of curvature 200 cm. The
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

5 examples of how intertia is used in real life
Mariulka [41]

Answer:

- your body moving forwards when sudden brakes/force is applied e.g. sudden braking in a car

- feeling a backwards force when something moves quickly from rest e.g a bus

- when you stir a cup of tea, it continues to swirl for a short period of time even though you have stopped

- when shaking a tree, it's leaves or fruit fall down

- satellites which move due to the inertia of motion

hope this helped :)
