Answer: 1.82
Explanation:
Given that the
Object distance U = 24.8 cm
Focal length f = 16.0 cm
Let us first calculate the image distance by using the formula
1/f = 1/u + 1/v
Substitute f and u into the formula
1/16 = 1/24.8 + 1/v
Make 1/v the subject of formula
1/v = 1/16 - 1/24.8
1/v = 0.0625 - 0.04032258
1/v = 0.022177419
Find the reciprocal of both sides
V = 45.09 cm
Magnification = image distance ÷ object distance
Magnification = 45.09/24.8
Magnification = 1.818
Therefore, magnification of the image is 1.82 approximately
60 miles / hr
= 60 * 1.6 * 1000 m / 60 * 60 s
= 96000 m / 3600 s
= 26.67 m / s
