Fluid viscosity is the property of the fluid that is responsible for the development of the velocity boundary layer. Non-viscous fluids do  not exhibit the property of velocity boundary layer in a pipe.

What is fluid viscosity?

Thickness of a fluid is called its viscosity. In liquids, velocity boundary layer is formed due to viscosity.

Viscosity is also termed as the flow rate of a liquid. If a liquid has a high flow rate then its viscosity is low and vice versa.

The fluid viscosity can be measured by using viscometer. The formula to measure viscosity is F = μA. u/y

Here F is force,  μ is fluid viscosity, A is the area and u/y sheer deformation rate.

On the contrary, a non-viscous fluid is one that has less thickness and can flow easily.

For example, water is a non-viscous fluid.

The third trial of the lab experiment did not work out because in most probability the magnets lost their magnetic properties or got demagnetized.

Demagnetization is the phenomenon by which magnets lose their magnetic property or are weakened. We see that the magnets moved just a little after she left them after the first two trials of her experiment. It is possible that because the magnets moved a little they repelled each other and this only happens when like poles face each other.

The demagnetizing field of one magnet will affect the other and vice versa because their magnetic fields are opposite in direction. Consequently, magnetic field strength weakens gradually. Thus the magnets did not work after the 3rd trial.

Neither of the two cylinders moves faster at the bottom. Both cylinders move with the same velocity at the bottom.

By the formula for conservation of energy, for a solid cylinder placed at the top of a ramp and rolling down to the bottom, we have

The kinetic energy of linear motion + rotational kinetic energy = potential energy                    (1)

Kinetic energy due to linear motion (of the center of mass of cylinder)= [tex]\frac{1}{2} mv^{2}[/tex]

Rotational kinetic energy = [tex]\frac{1}{2}Iw^{2}[/tex]

m = mass of cylinder, v = velocity of the center of mass of the cylinder

I = moment of inertia of solid cylinder = [tex]\frac{1}{2}mR^{2}[/tex]      (R = radius of cylinder)

angular velocity w = v/R  

g = acceleration due to gravity, h= height of the ramp

From equation (1)

[tex]\frac{1}{2}mv^{2}+ \frac{1}{2}Iw^{2} = mgh[/tex]

⇒[tex]\frac{1}{2}mv^{2}+\frac{1}{2}(\frac{1}{2}mR^{2}* \frac{v^{2} }{R^{2} } ) = mgh[/tex]

⇒[tex]\frac{1}{2}mv^{2}+\frac{1}{4}mv^{2}=mgh[/tex]

⇒[tex]\frac{3}{4}[/tex][tex]mv^{2} =mgh[/tex]

⇒v=√(4gh/3)              (cancel m on both sides)

Thus we see the velocity at the bottom of the sloping ramp that is v is independent of the mass or radius of the solid cylinders and only depends on the height of the ramp and acceleration due to gravity.

Thus both cylinders reach the bottom with the same velocity.

As a result of the law of conservation of momentum, the man will recoil as far as 0.034 m.

The law of conservation of momentum:

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

Where:

u₁ , u₂ = initial velocity of object 1 and object 2

v₁ , v₂ = final velocity of object 1 and object 2

Since both the player and the puck are initially at rest, hence  u₁ = 0, u₂ = 0.

Therefore,

m₁v₁ + m₂v₂ = 0

Parameters given:

m₁ = 80 kg

m₂ = 0.150 kg

v₂ = 47 m/s

Plug the parameters into the equation,

80 . v₁ + 0.15 . 47 = 0

v₁ = - 0.088 m/s

Because of this, race cars have streamlined bodies that enable them to go at significantly higher speeds.

As there is less surface area to push the air against, the streamlined designed car will be able to cut through the air and produce less drag or resistance. They move slowly, as opposed to autos, which are not streamlined. Because of this, race cars have streamlined bodies that enable them to go at significantly higher speeds.

A moving item possesses kinetic energy. If we want to accelerate an object, we must exert a force. Applying force requires effort on our part. Once the process is complete and energy has been transferred to the item, it will begin to move at a new constant speed.

Kinetic energy is the energy that an object has as a result of motion. It is defined as the work required to accelerate a mass-determined body from rest to the indicated velocity. Unless its speed changes, the body retains the kinetic energy it gained during acceleration.

Using the formula - K.E. = 1/2 × m × v²

K.E. = 1/2 × 0.4 × 20²

K.E. = 80 kg m/s²
