A camera lens produces a sharp image of a Distant object on the camera film when the lens is 2 cm from the film. how far must the lens be moved in order to photograph an object 50cm from the lens? A. 0.08cm away from the film
B. 4.5 cm away from the film
C. 0.08 cm nearer to the film
D. 0.06cm nearer to the film
E. 32cm away from the film​

0.19 m/s and 0.45 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
