velikii [3]

Answer:

Magnification m is 2.5cm

Explanation:

This problem bothers on lenses

Given data

Object distance u= 4cm

Height of object v= 10 cm

The problem is quite straightforward seeing that object and image distances are given

We know that the magnification

m= size of image/size of object

m= v/u= 10/4 = 2. 5cm

What is a convex lens

Dmitriy789 [7]

Answer:

1.37 seconds before.... splat !

Explanation:

y = y0 + v0 t + 1/2 a t^2      y0 = 30       y = 0

                    v0 = 0 ( from rest)

                            a = - 32.2 ft/s^2

0 = 30 - 1/2 * 32.2 * t^2

t=1.366 seconds                   <u>  Note that   mass   is irrelevant.</u>
