Mirror formula

1/f = (1/p) + (1/q)    [ f= focal length  ,  p= object distance ,  q = image distance ]

as given convex mirror so

distance of object =p= 6cm

focal length =  -8cm

to find q=?

1/q =( 1/f) - (1/ p)

1/q = (1/ 8) -(1/6)

1/q =-1/24

q=-24  ( negative sign shows image is virtual and behind the mirror)

Olivia wants to find out whether a substance will fluoresce. She says she should put it in a microwave oven. Do you agree with h
andreyandreev [35.5K]
Disagree.
Fluoresce objects will only glow when put under actual Ultraviolet light. This is due to the molecules becoming excited by the ultraviolet radiation.


Microwaves give micro-waves that are present in another spectrum of wave length and will not be able to fluoresce the molecules. If it’s not “ultra violet “.... it’s not going to glow.

Total work done is 0.13 Joules

<h3>What is work done ?</h3>

The sum of the displacement and the component of the applied force of the object in the displacement direction is the work done by a force.

According to the given information

We need to find the work done

work done  = force × distance

We are given,

force  = 26 N

Distance = 0.0005 meter

hence ,

Work done  = 26 × 0.005  

                   = 0.13 Joules

Total work done is 0.13 Joules
