poizon [28]3 years ago
4 0

Answer:

i) 5 m/s^{2}  ii) 54 N  iii) 54 N

Explanation:

i) a = \frac{v^{2}}{r} ⇒ a = 5² ÷ 5 = 5 m/s^{2}

ii) m = \frac{W}{g} ⇒ m = 108 ÷ 10 = 10.8 kg , F = ma ⇒ F = 10.8 × 5 = 54 N

iii) F1 = F2 = 54 N

A camera takes a properly exposed photo with a 4.0 mm diameter aperture and a shutter speed of 1/1000 s. If the photographer foc
hoa [83]

Answer:

option E

Explanation:

given,

diameter = 4 mm

shutter speed = 1/1000 s

diameter of aperture = ?

shutter speed = 1/250 s

exposure time to the shutter time

E V = log_2(\dfrac{N^2}{t})

N is the diameter of the aperture and t is the time of exposure

now,

log_2(\dfrac{N^2}{t_1})=log_2(\dfrac{N^2}{t_2})

\dfrac{N_1^2}{t_1}=\dfrac{N_2^2}{t_2}

inserting all the values

\dfrac{4^2}{1000}=\dfrac{N_2^2}{250}

      N₂² = 4

      N₂ = 2 mm

hence , the correct answer is option E
