Answer:
When a an object is been rotated its resistance capacity to that rotational force is know as rotational inertia and this mathematically given as
Where m is the mass
r is the rotation radius
For the spinning of the lamp as a baton to work the location of the center of mass of the floor lamp needs to be located
This is more likely to be located closer to base of the lamp as compared to the top, so success of spinning a floor lamp like a baton is highly likely if the lamp is grabbed closer to the base because that is where the position of its center of mass is likely to be.
Explanation:
Answer:
upwards
Explanation:
Torque is the vector cross product of the force and radial distance.
The direction of the torque would be perpendicular to the direction of the force and radial distance. The direction of the force is counter-clockwise. The direction of the torque would be upwards.
Answer:
Explanation:
first write the newtons second law:
F=δma
Applying bernoulli,s equation as follows:
∑
Where, is the pressure change across the streamline and
is the fluid particle velocity
substitute for {tex]γ[/tex] and
for
integrating the above equation using limits 1 and 2.
there the bernoulli equation for this flow is
note: =density(ρ) in some parts and change(δ) in other parts of this equation. it just doesn't show up as that in formular
