Then driving force for the membrane is hyperpolarized.
What is equilibrium potential?The electrical potential difference across the cell membrane that exactly balances the ion concentration gradient is known as the equilibrium potential. Since the system is in equilibrium, the membrane potential will normally stay at the equilibrium potential.
Additionally, the equilibrium potential for a group of ions in a membrane provides us with a baseline for how this membrane is operating or behaving in a given situation where it is not at rest.

How frequently should the product owner re-iterate the product vision to the scrum team?
For a project to be successful, the product owner should invest somewhere between 60 and 100 percent of their time and effort in it.
In many aspects of product development, the scrum product owner assumes leadership. They will eventually need to use their extensive market knowledge to plan and communicate their vision to stakeholders. They will have to put on their developer hats one more time in order to assist the team in achieving its sprint objectives.

What is the relationship between a boats volume and the amount of mass it can hold
The relationship between a boats volume and the amount of mass is known as Archimedes' principle
Archimedes' principle states that an object displaces its personal weight in a liquid.
So calculate the weight of the boat from the mass. Calculate the quantity of liquid that has this equal weight. that is the quantity of boat underneath the waterline.
Divide that variety with the aid of the vicinity of the boat (duration instances width). this is the depth the boat sinks to.
what is Archimedes principle in easy words?
Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force identical to the burden of the displaced fluid. that is a primary condition of equilibrium. We take into account that the above force, referred to as pressure of buoyancy, is placed in the centre of the submerged hull that we name centre of buoyancy.

The quantum number of a particle of mass m confined to a one-dimensional box of length l when its energy is 2 h2/ml2 is 4.
What is quantum number?
The collection of numbers known as quantum numbers is used to describe an electron's position and energy in an atom. The four categories of quantum numbers are primary, azimuthal, magnetic, and spin quantum numbers.
Given that,

Q(l) = 35,000 kj/h
T° = 4° c = 277k
T(H) = 298 k
given that house is to be maintained at 25° c at all times
hence internal energy is zero. du=0
now, using first law of thermodyanamics
dq= du+dw
dq= dw ( because du = 0)
hence, heat lost by house is equal to the work input for system
Q(l)= w (input)
w (input) =35,000 kj/hr
now, coefficient of performance for reversible heat pump = cop ( rev,hp)
cop ( rev,hp) = = 14.9
cop ( rev,hp) = Q(l)/w (input)
14.9 = 35,000/ (win)rev
(win)rev = 2349 kj/h ( reversible work input)

The most amazing and unexpected truth about falling things is that, in a given location, all items fall toward the center of the Earth with the same constant acceleration, regardless of their mass, if air resistance and friction are low.
So here is the most straightforward formula for this:

In general, a phenotype is an inherited trait that we can observe.
Phenotypes include things like blood type, eye colour, and hair colour. If you have brown eyes, your eyes will be brown; if you have brown hair, your hair will be brown; or if you have an A blood type phenotypic, your blood type will be A.
Only the blue allele can be passed down from the homozygous blue-eyed parent. Either the blue allele or the brown allele can be inherited from the heterozygous brown-eyed parent. Children with a blue-brown genotype, or those with both the blue and brown alleles, will have brown eyes and a brown-eyed phenotype.

4. The diagram shows two forces of 5 N and 8 N acting at 120° to each other. Calculate the resultant of these two forces and state its direction relative to the 5 N force. Illustrate your answer with an appropriate vector diagram.
The magnitude of the resultant force is 11.4 N.
What is the resultant force?The resultant force is the force that has the same effect both in magnitude and in direction as the two or more forces acting at the same time. We know that force is a vector quantity, this implies that both the magnitude and the direction of the force are all important. This is why we have to factor in the direction of the force at all times.
Now, we can see that, it is possible to obtain the resultant force from the parallelogram law of vectors. We can see that;
R = √ P^2 + Q^2 - 2PQ Cos θ
P = 5 N
Q = 8 N
θ = 120°
R = √(5^2 + 8^2 - (2 * 5 * 8) cos 120

To find the index of refraction, the given values are:
Critical angle is 68.4°.
What is the refractive index?The refractive index can be defined as the ratio of the speed of light in the medium to the speed in the vacuum.
The formula of the refractive index is as follows:
Where,
n is the refractive index
c is the velocity of light in a vacuum ( 3 × 108 m/s)
v is the velocity of light in a substance
The vacuum has a refractive index of 1. The refractive index of other materials can be calculated from the formula mentioned. Higher the refractive index, the higher the optical density and slower is the speed of light.The refractive index of different media can be listed in the table below:
Material Refractive Index
Air 1.0003
Water 1.333
Diamond 2.417
Ice 1.31
Ethyl Alcohol 1.36
Now, finding the value of refractive index,
As the value of critical angle is given, θ = 68.4°,
θc = Sin ⁻¹ ([tex]\frac{n2}{n1}[/tex])
Considering the given values, n2 = 1.3333
θc = θ = 68.4°

According to the given question distance between these two points is 1.971m.
What do you mean by distance?The distance can be a literal length as defined by physics or a general estimation based on other variables. It is a generalization of the idea of physical distance. Distance is a non-numerical unit of measurement in psychology and the social sciences; psychological distance is the separation of an object from itself along dimensions including time, space, and isolation.
According to the question:
speed=frequency*wavelength
wavelength = 340/140 =2.428 m
phase difference=2pi× x/lamda
x=5.1*2.428/(2*pi)
x=1.97m
since v= f × wavelength
where v = speed of sound and f = frequency
therefore wavelength = v/f = (340)/140 = (17/7)m
now, since Phase angle = (2×pi/wavelength)×shift
or, shift = phase angle × (wavelength/2×pi) = 5.1 × ((17/7)/2×pi) = 1.971m

V(t) = s'(t)
Or, V(t) = 4t³ - 7 × 1 + 0
Or, V(t) = 4t³- 7
Hence, the velocity at time t is 4t³- 7.
B) Velocity ar time t = 3 is
V(3) = 4(3)³- 7
Or, V(3) = 101 ft/sec
Hence, the velocity at time t = 3 is 101 ft/sec.
(C) When particle is at rest, V(t) = 0
Then, 4t³ - 7 = 0
Or, t³ = 7/4
Or, t = ∛7/4 sec
Therefore, the velocity at rest is ∛7/4 sec.

If 2 objects at different temperatures are in contact with each other what happens to their temperature
When two objects of different temperatures come into contact with each other, equilibrium is reached and energy is transferred from the hotter object to the cooler object until the objects reach thermal equilibrium (that is, they are at the same temperature).
When one object heats another, the increase in the temperature of one object is not always the same as the decrease in the temperature of the other, because the specific heat of one object is higher than the other.
Objects exchange thermal energy until they are at the same temperature. When two objects with different temperatures come into contact, they eventually achieve the same temperature. This is because of the thermal equilibrium.
Heat Transfer: Heat Transfer from Warmer Object to Cooler Object - When two substances at different temperatures are mixed, heat is transferred from a hotter object to a cooler object until the same temperature is reached (zero law of thermodynamics) - thermal equilibrium).
