When an object experiences centripetal acceleration, in which direction does it accelerate?
2 answers:
Centripetal acceleration points from the object toward the center of the circular path it's traveling.
Answer:
Option (a)
Explanation:
When an object is moving around an circular path it experiences an force towards the centre of circular path radially. This force is called centripetal force.
Due to the centripetal force a centripetal acceleration is also acting on the body which also have same direction as force that is radially inwards.

Explanation:
Answer:
(a): The car's relative position to the base of the cliff is x= 32.52m.
(b): The lenght of the car in the ir is tfall= 1.78 sec.
Explanation:
Vo= 0
V= ?
d= 50m
h= 30m
a= 4 m/s²
t= √(2*d/a)
t= 5 sec
V= a*t
V= 20 m/s
Vx= V * cos(24º)
Vx= 18.27 m/s
Vy= V* sin(24º)
Vy= 8.13 m/s
h= Vy*t + g*t²/2
clearing t:
tfall= 1.78 sec (b)
x= Vx * tfall
x= 32.52 m (a)
Answer:
a)54L/min
b)0.845
Explanation:
a) A x V=
where suffix 1,2,3 refers to the three pipes.
=27L/min+16L/min+11 L/min
=54L/min
b) A x V=54L/min =>
d= 2 cm
v=
->
Next is to find the ratio of speed i.e
