1. An object 20 cm away from a lens produces a focused image on a film 15 cm away, what is the focal length

morpeh [17]

8.6 cm

Explanation:

Step 1:

In this we have to find the focal length of converging lens.

To find focal length we have,

$(1/u) + (1/v) = (1/f)$

where u = Object distance

v= Image distance

f = Focal length

Step 2:

$(1/f) = (1/20) + (1/15)$

(1/f) = 0.116

f = 1/0.116

f = 8.6 cm

A 50 kg skydiver is falling downwards and accelerating 6 m/s2 down. What is the net force on the skydiver?

Montano1993 [528]

Net Force = (mass) x (acceleration) (Newton #2)

Net Force = (50 kg) x (6 m/s² down)

Net Force = (50 * 6) (kg-m/s² down)

<em>Net Force = 300 Newtons down</em>
