Explanation:

given data

worked on homework time = 1.5 hour

completed = 6 problems

to find out

What is the velocity in problems per hour

solution

we know that Shirley solve complete 6 accounting homework problem in 1.5 hour so her velocity in problems per hour will be as

velocity in problems per hour = $\frac{complete\ problem}{time\ taken}$ ..................1

put here value we will get

velocity in problems per hour = $\frac{6}{1.5}$

velocity in problems per hour = 4 per hour

You buy a magnifying glass at the store. The lens in the magnifying glass is a double convex lens, a lens with two convex curved

Leokris [45]

Answer:

30 cm

Explanation:

f = Focal length = 25 cm

R = Radius of curvature (both sides are equal)

$\mu$ = Refractive index of lens = 1.6

The lens maker formula is given by

$\frac{1}{f}=(\mu-1)(\frac{1}{R_1}-\frac{1}{R_2})\\\Rightarrow \frac{1}{f}=(\mu-1)(\frac{1}{R}-\frac{1}{-R})$ minus sign because it is on the other side
