In a 35 mm single lens reflex camera (SLR) the distance from the lens to the film is varied in order to focus on objects at vary
Evgesh-ka [11]

Answer:

range of movement is 1.49 mm

Explanation:

given data

focal length = 45 mm

distance = 1.4 m

distance from the lens = 35 mm

distance from infinity down = 1.4 m =

to find out

range of movement

solution

we will apply here lens equation that is

1/f = 1/p + 1/q

here f = 45 and p =  infinity to 1400 mm

we find here image distance that is q

1/45 = 0 + 1/q             ......1

q = 45 mm

and

1/45 = 1/1400 + 1/q     ......2

q = 46.49

so range of movement

that is 46.49 - 45

range of movement is 1.49 mm

A negative velocity, approaching zero, represents a negative acceleration. True or False
ruslelena [56]

Answer:

False.

Explanation:

Lets assume our positive direction to the right (this reasoning works for any direction). A negative velocity would then be then directed to the left. If it varies as such that it aproaches to zero, it means that the variation is directed to the right, and that is where the direction of the acceleration must be pointing. In other words, its losing its velocity, so the acceleration must point opposite to the velocity. Then it means the acceleration is positive.
