Answer:
17.4 cm
Explanation:
Power of lens = +1.75 diopters
Focal length of lens
This is a convex lens as focal the diopter given is positive which makes the focal length positive. Image distance will be negative.
v = -25
∴ The new near point is 17.4 cm
The speed of bullet =
850 m/s
Distance given = 1 km = 1000m
S = D/t
t • S = D/t • t
St = D
St/S = D/S
t = D/S
t = 1000m/850m/s
t = 1.176 s
It will take the bullet 1.176 or about 1.18 seconds to go 1 km.
