An object is placed 25 cm from a convex lens whose focal length is 10 cm. The image distance is ________ cm.
1 answer:
16.67cm
Explanation:
Given parameters:
Object distance, U = 25cm (u is -25cm for convex lens)
Focal length = 10cm
Unknown parameter:
Image distance, V = ?
Solution
To solve for the image distance, we use the equation:
Images in a convex mirrors are real, inverted, smaller than the object
=
-
=
-
image distance = 16.67cm

Answer:
option C
Explanation:
given,
diameter of circular room = 8 m
rotational velocity of the rider = 45 rev/min
=
=4.712 rad/s
here in this case normal force is equal to centripetal force
N = m r ω²
N = m x 4 x 4.712²
N = 88.83m
frictional force = μ N
= 88.83m x μ
now, for the body to not to slide
gravity force is equal to frictional force
m g = 88.83 m x μ
g = 88.83 x μ
9.8 = 88.83 x μ
μ = 0.11
hence, the correct answer is option C
