A 6 cm object is 15 cm from a convex lens that has a focal length of 5 cm. What is the distance of the image from the lens, to t
sweet [91]
So we want to know what is the distance d of the object from the lens if the height of the object is h=6 cm, focal length of the lens is f=5 cm and the distance d=15 cm is the distance of the object from the lens. From the formula for the convex lens 1/f=(1/D + 1/d) where D is the distance of the image from the lens we can get D after solving for D: 1/D=(1/f) - (1/d),
1/D=(1/5)-(1/15)=0.2-0,06667=0.13333 so f=1/0.13333=7.500187 cm. Rounded to the nearest hundredth D=7.50 cm.  That is very close to 7.69 cm so the correct answer is the third one.

Law Incorporation [45]

Answer:

5/6 = 0.833

Explanation:

From conservation of momentum,

m1*u1  + m2*u2 =  (m1+m2)*v

v = (m1*u1 + m2*u2)/(m1*m2)

Putting in the values, we get, v = 5/6 = 0.833
