Answer:
122.5 N
Explanation:
The free body diagram in the bucket at the top of the circle is shown in the attached image.
The force balance hence, is
T + mg = mv²/r
where T = tension in the rope = ?
mg = weight of the bucket system
mv²/r = force keeping the bucket in circular motion.
v = velocity of the bucket = 7.8 m/s
r = radius of the circular path = 1.0 m
T + mg = mv²/r
T + (2.4×9.8) = (2.4×7.8²)/1
T = 146.016 - 23.52 = 122.496 N
In a parallel circuit nothing happens. All the other lights stay on but if it was a series circuit ALL the lights would turn off at one time.
If there is an ABCD question I can answer that but I wasn't sure so I just said this
Hope it is helpful :)
Answer:
u = 6.667 cm
Explanation:
given,
Focal length of the concave mirror, f = 20 cm
magnification factor = 1.5
we know,
v is the distance of the image
u is the distance of the object
v = -1.5 u
Using mirror formula
u = 6.667 cm
distance of the person from the mirror is equal to 6.667 cm.
