Answer:
t = 6.09 seconds
Explanation:
Given that,
Speed, v = 44.1 cm/s
Distance, d = 269 cm
We need to find the time interval of the marble. Speed is distance per unit time.
Hence, the time interval of the marble is 6.09 seconds.
Answer:
34.70 N
Explanation:
Given :
F~ 1 = 43 N in direction 38◦
F~ 2 = 26 N in direction −140◦
F~ 3 = 27 N in direction 110◦
Therefore,
F~x = 43 cos (38) + 26 cos (-140) + 27 cos (110)
= 43 (0.7) + 26 (-0.7) + 27 (-0.3)
= 3.8
F~y = 43 sin (38) + 26 sin (-140) + 27 sin (110)
= 43 (0.6) + 26 (-0.6) + 27 (0.9)
= 34.5
so, F~ =
= 34.70 N
Answer:
B) The image is virtual and 12 cm from the lens
Explanation:
u = Object distance = 6.5 cm
v = Image distance
f = Focal length = 14 cm
Lens Equation
Focal length of the lens is -12 cm. The negative sign implies the image is virtual in nature.
