A photographer wants to take a picture of a bird 1.50 m away with a 35.0mm lens. How far from the lens must the film in a camera be

Therefore, the film in a camera must be  placed at a distance of 0.0358m, 3.58cm 0r 38.5mm depending on the unit.

Explanation:

From the question, we have that,

Focal length of the lens, f = +35 mm = 35/ 1000 = 0.035m

The Object distance of the flower, u = 1.50m

The image distance, v = ?

. Using lens formula as, we have that  

1/f = 1/u + 1/v

where f= the focal length

u =the object distance

v=image distance

1/ 0.035 =  1/1.50 +1/v

1/v = 1/0.035- 1/1.50

=28.57- 0.667

=27.903

1/v= 27.903

v = 1/27.903

v= 0.0358 m

Therefore, the film in a camera must be  placed at a distance of 0.0358m

it becomes positively charged by charging it

i think the answer would be reserve.
