Explain why the resistance of the current path through the extracellular fluid is much smaller than the resistance of the current path through the axoplasm. What gives rise to the potential difference between the extracellular fluid and the axoplasm?
Answer:
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.
What is 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.

Which elastic modulus describes the relationship between stress and strain for a block of iron sliding across a horizontal floor? The friction force between the sliding block and the floor causes the block to deform.
A. Young's Modulus
B. Shear Modulus
C. Bulk Modulus
D. None of these
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.
A massive tractor is rolling down a country road. In a perfectly inelastic collision, a small sports car runs into the machine from behind. (i) Which vehicle experience a change in momentum of larger magnitude? (a) The car does. (b) The tractor does. (c) Their momentum changes are the same size. (d) It could be either vehicle. (ii) Which vehicle experiences a larger change in kinetic energy? (a) The car does. (b) The tractor does. (c) Their kinetic energy changes are the same size. (d) It could be either vehicle.
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).
A 2.93 kg particle has a velocity of (2.98 i hat - 3.98 j) m/s.
Required:
a. Find its x and y components of momentum.
b. Find the magnitude and direction of its momentum.
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 crate with a mass of 1000 kg is being pulled along greased tracks by a winch. The winch is exerting a force of 2000 N
in the horizontal direction along the tracks. The coefficient of kinetic friction between the crate and the tracks is 0.2.
20. What is the net force acting on the crate in the horizontal direction?
21.
Using Newton's second law, calculate the crate's acceleration.
Coefficient of Kinetic Friction = 0.2
Mass of the crate = 1000 kg
Force applied = 2000 N
Net force Acting on the crate in the Horizontal Direction:Normal Force applied on the Crate: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
Finding the Frictional Force: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
Net force acting on the Crate:
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
Acceleration of 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
convert 1000m/10s in km/h (with explenation)

I've been stuck on this for two hours:
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.
Express your answer numerically in cubic meters per second.
The discharge rate of water (Q) that flows across the exit of the pipe in 1.00 seconds is 0.200 [tex]m^3/s[/tex].
Given the following data:
Elevation of point 1 = 10.0 mElevation of point 2 = 2.00 mElevation of point 3 = 2.00 mCross-sectional area at point 2 = [tex]4.80\times 10^{-2} \;m^2[/tex]Cross-sectional area at point 3 = [tex]1.60\times 10^{-2} \;m^2[/tex]To find the discharge rate of water (Q) that flows across the exit of the pipe in 1.00 seconds assuming that Bernoulli's equation applies:
In this exercise, we would apply Torricelli's Law, which states that the speed of the efflux in an apparatus, under the force of gravity is directly proportional to the square root of the height of the fluid above it.
Mathematically, Torricelli's Law is given by the formula:
[tex]V =\sqrt{2gh}[/tex]
Where:
g is the acceleration due to gravity.h is the height of the apparatus.V is the speed of liquid.Substituting the given parameters into the formula, we have;
[tex]V =\sqrt{2 \times 9.8 (10-2)}\\\\V =\sqrt{19.6 (8)}[/tex]
Speed, V = 12.52 m/s
Now, we can find the discharge rate of the pipe:
[tex]Q = V \times A\\\\Q = 12.52 \times 1.60\times 10^{-2}[/tex]
Discharge rate, Q = 0.200 [tex]m^3/s[/tex]

as an object falls:
a) both velocity and acceleration increase
b) velocity increases and acceleration decreases
c) velocity increases and acceleration is unchanged
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.
What do you mean by velocity ?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.

Why is a cell phone more likely to break when dropped from a higher height than a lower one?
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.
What is potential energy?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.

it is dangerous to stand near the railway leak when train passing by,why?
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.
