Water flows steadily from an open tank as shown in the figure. (Figure 1)The elevation of point 1 is 10.0 m , and the elevation of points 2 and 3 is 2.00 m . The cross-sectional area at point 2 is 4.80×10−2 m2 ; at point 3, where the water is discharged, it is 1.60×10−2 m2 . The cross-sectional area of the tank is very large compared with the cross-sectional area of the pipe.



Assuming that Bernoulli's equation applies, compute the volume of water ΔV that flows across the exit of the pipe in 1.00 s . In other words, find the discharge rate ΔV/Δt.

Answer:

Because a person may be pulled in the direction of the moving train. Thereby causing accident

Explanation:

According to Daniel Bernoulli's theorem, he was widely known as a Mathematician. He stated that due to the higher velocity of a moving train, there is higher kinetic energy in terms of volume around it, while the air pressure between the person and the train becomes lower.

As a result, a person near a moving train may be pulled in the direction of the moving train. Thereby causing accidents that may lead to death.

Answer:

B. Shear Modulus

Explanation:

In this scenario, the friction force between the sliding block and the floor causes the block to deform.

Hence, the elastic modulus which describes the relationship between stress and strain for a block of iron sliding across a horizontal floor is Shear Modulus.

Shear Modulus can be defined as the ratio of shear stress to shear strain with respect to a physical object.

This ultimately implies that, Shear Modulus arises as a result of the application of a shear force on an object or body which eventually leads to its deformation. Thus, this phenomenon is simply used by scientists to measure or determine the rigidity of an object or body.

Mathematically, Shear Modulus is given by the formula;

[tex] G = \frac {Fl}{ADx} [/tex]

Where;

G is the Shear Modulus.

F is the force applied to the object.

A is the area of the object.

l is the length of the object.

Dx is the change in length.

Shear Modulus is measured in Pascals.

Answer:

a) The x and y components of the momentum are [tex]8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]-11.661\,\frac{kg\cdot m}{s}[/tex], respectively.

b) The magnitude and direction of its momentum are approximately 14.567 kilogram-meters per second and 306.823º.

Explanation:

a) The vectorial equation of momentum is represented by the following expression:

[tex]\vec p = m\cdot \vec v[/tex] (1)

Where:

[tex]\vec p[/tex] - Vector momentum, measured in kilogram-meters per second.

[tex]m[/tex] - Mass of the particle, measured in kilograms.

[tex]\vec v[/tex] - Vector velocity, measured in meters per second.

If we know that [tex]m = 2.93\,kg[/tex] and [tex]\vec v = 2.98\,\hat{i}-3.98\,\hat{j}\,\,\,\left[\frac{m}{s} \right][/tex], then the momentum is:

[tex]\vec p = (2.93)\cdot (2.98\,\hat{i}-3.98\,\hat{j})\,\,\,\left[\frac{kg\cdot m}{s} \right][/tex]

[tex]\vec p = 8.731\,\hat{i}-11.661\,\hat{j}\,\,\,\left[\frac{kg\cdot m}{s} \right][/tex]

The x and y components of the momentum are [tex]8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]-11.661\,\frac{kg\cdot m}{s}[/tex], respectively.

b) The magnitude and direction of momentum are represented by the following expressions:

[tex]\|\vec p \| = \sqrt{p_{x}^{2}+p_{y}^{2}}[/tex] (2)

[tex]\theta = \tan^{-1}\left(\frac{p_{y}}{p_{x}} \right)[/tex] (3)

Where:

[tex]\|\vec p\|[/tex] - Magnitude of momentum, measured in kilogram-meters per second.

[tex]\theta[/tex] - Direction of momentum, measured in sexagesimal degrees.

If we know that [tex]p_{x} = 8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]p_{y} = -11.661\,\frac{kg\cdot m}{s}[/tex], then the magnitude and direction of momentum are, respectively:

[tex]\|\vec p\| = \sqrt{\left(8.731\,\frac{kg\cdot m}{s} \right)^{2}+\left(-11.661\,\frac{kg\cdot m}{s} \right)^{2}}[/tex]

[tex]\|\vec p\| \approx 14.567\,\frac{kg\cdot m}{s}[/tex]

[tex]\theta =\tan^{-1}\left(\frac{-11.661\,\frac{kg\cdot m}{s} }{8.731\,\frac{kg\cdot m}{s} } \right)[/tex]

[tex]\theta \approx 306.823^{\circ}[/tex]

The magnitude and direction of its momentum are approximately 14.567 kilogram-meters per second and 306.823º.

A cell phone more likely to break when dropped from a higher height than a lower one because it has more potential energy at high height.

Potential energy is the energy stored by an object as a result of its position relative to other objects, internal tensions, electric charge, or other reasons.

Potential energy is commonly defined as an object's gravitational potential energy, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The joule is the SI unit of energy.

Although it has connections to the Greek philosopher Aristotle's concept of potentiality, the word potential energy was coined by the 19th-century Scottish engineer and physicist William Rankine.

A turbine and generator produce the electricity

"A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.

Coefficient of Kinetic Friction = 0.2

Mass of the crate = 1000 kg

Force applied = 2000 N

Normal force is the force applied on the object by the surface. It is equal and opposite to the force of gravity

So, we can say that Normal force = | Gravitational Force |

Normal Force = | mg |

Normal Force = 1000 * 9.8

Normal Force = 9800 N

We know that:

coefficient of Kinetic friction = Friction force / Normal force

replacing the known values

0.2 = Friction force / 9800

Friction Force=  0.2 * 9800

Friction Force = 1960 N

We know that a force of 2000 N is being applied on the crate in the Horizontal direction

Frictional force is always opposite to the horizontal force. So, we can say that:

Applied force - Friction Force = Net Force

replacing the variables

2000 - 1960 = Net force

Net Force = 40N

Therefore, a net force of 40N is being applied on the Crate

From newton's second law of motion:

F = ma

replacing the variables

40 = 1000 * a

a = 40/1000

a = 0.04 m/s²

Hence, the crate will have an acceleration of 0.04 m/s²

Explanation:What Gives Rise To The Potential Difference Between The Extracellular Fluid ... is much smaller than the resistance of the current path through the axoplasm.

Neurons in the axoplasm is acting like a leaky cable and its resistivity increases with length. The axon membrane will transfer the ions to te organelle called axolemma and thus the resistance of current path is more for axoplasm.

The cytoplasm found inside a neuron's axon is called axoplasm . This may account for more than 99% of the cytoplasm in some types of neuronal cells .

Organelles and other components of the axoplasm are different from those of the dendrites and cell body (soma) of the neuron. Materials are transported to or from the soma through the axoplasm during axonal transport, also referred to as axoplasmic transport.

One characteristic of a neuron's cable is its electrical resistance, or axoplasmic resistance, which influences how quickly an action potential travels down an axon.

The potential will move more slowly if the axoplasm contains a lot of molecules that are not electrically conductive because more ions will pass through.

Explanation:

In an inelastic collision, the momentum remains conserved while the kinetic energy is not conserved.

(i) Here, a small sports car runs into the machine from behind.

Due to the conservation of momentum, it remains conserved. It means their momentum changes are the same size.

Hence, the correct option is (c).

(ii) The car is moving faster than the tractor. A faster moving object will lose more energy as compared to the other. It means car's most of the energy is converted to internal energy. The car will have a a larger change in kinetic energy. Hence, the correct option is (a).

Explanation:9 (- _ -)

Answer:

c it is not accelerating on it's on but gravity pulls it there for velocity increases.

As an object falls, velocity increases and acceleration is unchanged. Therefore, option C is correct.

The term velocity is defined as the direction of the movement of the body or the object.

Speed is fundamentally a scalar quantity. Velocity is, in essence, a vector quantity. It is the rate at which distance changes. It is the displacement rate of change.

The velocity of something is the rate at which it moves in a specific direction. For example, the speed of a car driving north on a highway or the speed of a rocket after launch. The scalar denotes that the absolute magnitude of the velocity vector is always the speed of motion.

Thus, it is not accelerating on it's on, but gravity pulls it there as velocity increases.
