Answer:
one ninth
Explanation:
d = 1 cm , v = v
D = 3d, V = ?
By the equation of continuity,
A V = a v
3.14 x D^2 / 4 x V = 3.14 x d^2 / 4 x v
9d^2 x V = d^2 x v
V = v / 9
Thus, the velocity becomes one ninth the initial velocity
Answer:
So, the force, F is the agent which provides the basic property of motion or rest to the body.While, the car is more obviously to have a mass, m and that the angle withe road or surface is also given which is normal to the road(i.e angle =90 degree). Then we say that lets say that the car is moving with the constant velocity of 20 m/sec and its kept unchanged by the car. So, we have the mass, m as 1 kg for the car and the value of the gravity we have the g=9.8 m/sec.
Now,
We have F=ma,
and a=v/t,
so we can have another equation for it as,
Now, providing the required data to, it; ∴t =2 sec,
F=(1)×(20/2),
- So, the car would be acting the force,F of about 10 N while the car is present on the lower region of the track.
