A concentration gradient drives the ion-exchange membrane (IEM) separation procedure known as diffusion dialysis (DD).

Diffusion dialysis is referred to be a spontaneous separation technique since the concentration gradient primarily drives the separation process. A membrane separation procedure is DD.

Diffusion is the movement of a solute along a concentration gradient through a membrane. Small molecules are eliminated in this manner during hemodialysate. Diffusion is the net transfer of a substance from a location of high concentration to a region of low concentration, according to physicists and chemists.

Diffusion in hemodialysis is formally defined as the transport of solutes as a result of random molecular motions down its concentration gradient through a semipermeable membrane. Diffusion is how most toxins are removed during dialysis.

We can use this kinematics equation to evaluate time.

[tex]y=v_0t-\frac{1}{2}gt^2[/tex]

Lets solve for [tex]t.[/tex]

Combine [tex]\frac{1}{2}[/tex] and [tex]gt^2[/tex].

[tex]y=v_0t-\frac{gt^2}{2}[/tex]

Subtract [tex]y[/tex] from both sides.

[tex]0=v_0t-\frac{gt^2}{2}-y[/tex]

[tex]0=-\frac{gt^2}{2} -v_0t-y[/tex]

Multiply both sides of the equation by -1.

[tex]0=\frac{gt^2}{2} -v_0t+y[/tex]

Multiply both sides of the equation by 2.

[tex]0=gt^2 -2v_0t+2y[/tex]

Use the quadratic formula to solve for t.

If friction is neglected, at any given instant both objects will have the same c) Height.

Friction is the resistance to motion that results from two objects rubbing against one another. Two objects rubbing against one another causes friction. Motion is opposed by friction, which works against the motion.

When an object slides over another object, friction slows it down. As a result, energy is used. However, the energy does not fade away.

Answer: The amount of Torque produced is 7.2 Nm.

Explanation:

Given:

Force applied (F) to the end of a wrench = 60 Newton

Length of wrench = 0.12 meter

To find:

Quantity of Torque produced

Solution:

The quantity of Torque produced can be calculated from the following formula:

Ƭ = r F sin(θ)  

Where,

Ƭ = Torque, r = radius, F = Force,  (θ) =  angle between F and the lever arm  

In the given question,

r = 0.12,

F= 60,

(θ)= 900           {Since the force is applied at the end of a wrench, it must be perpendicular}

Torque (Ƭ) = 0.12* 60 * sin 900

               = 7.2 m                    {sin 900 = 1}

Hence, in the given situation, 7.2 Nm Torque will be produced.

The total rotational kinetic energy of the two hands about the axis of rotation is calculated using the formula:

Kinetic Energy = 1/2 I ω2,

where I is the moment of inertia and ω is the angular velocity.

For this scenario, the moment of inertia is calculated by

I = 1/3 ML2,

where M is the total mass and L is the length of the arm.

Since the total mass of the two hands is 169.5 kg, and the length of the arms is 2.71 m and 4.4 m, the moment of inertia is calculated to be I = 5.35 x 10-5 kg m2. Substituting this value of I into the equation, the total rotational kinetic energy of the two hands about the axis of rotation is calculated to be 1.04 x 10-3 J.

The acceleration of a dolly-sandbag system when mass and coefficient of kinetic friction is given is calculated to be 0.29 m/s².

Given that,

The mass of the dolly and actor combined M = 76 kg

The mass of the sandbag m = 18 kg

The coefficient of kinetic friction between the dolly and the stage floor = 0.20.

Let the acceleration is a.

From Newton's 2nd law of motion, we can write that,

ΣF = (m+M) a

mg - μMg = (m+M) a

a = g (m- μM)/ (m+M)

a = 9.8 ( 18 - 0.20×76)/(18+76)

Answer:

The two resistors should be connected in series.

(I assume that the question is stating the electrical power consumed by the resistors)

Explanation:

Think about the formula P = V^2 / R

For the electrical power consumed to be a minimum, we must let V be as small as possible.

For small V, between a series and a parallel connection, series is the correct connection as the combined potential difference (pd) for the two resistors is equal to the electromotive force (emf) of the battery.

However, for parallel connections, the combined pd for the two resistors is equal to twice the emf of the battery. (Each resistor will have a pd equal to the emf of the battery)

With lower total V, with the same R, power P consumed will decrease.

The coefficient of viscosity of a liquid can be determined from the motion of a bubble rising or falling through the liquid.

What is viscosity?

Viscosity basically is the measure of a fluid's resistance to flow. It is a measure of a fluid's internal friction, which is caused by the attraction of molecules in the fluid. Viscosity is an important physical property of fluids, as it affects the fluid's flow characteristics.

The equation for the coefficient of viscosity is given by:

where,

r = radius of bubble

ρ = density of liquid

g = acceleration due to gravity

v = velocity of bubble

Therefore, to calculate the coefficient of viscosity of a liquid, we need to know the radius of the bubble, the density of the liquid, the acceleration due to gravity, and the velocity of the bubble.

Explanation:

Answer:

a) The direction of the current in the copper rod that causes the springs to stretch is left-to-right. This is because the magnetic field is oriented perpendicular to the surface of the table and the force exerted on the rod by the magnetic field is given by F = qVB, where F is the force, q is the charge of the particle, V is the velocity of the particle, and B is the strength of the magnetic field. Since the force is perpendicular to the velocity of the particle, the direction of the current that produces this force must be parallel to the magnetic field. In this case, the magnetic field is oriented perpendicular to the surface of the table, so the current must flow in the direction left-to-right to produce a force that stretches the springs.

b) To find by how much each spring stretches, you can use the formula F = kx, where F is the force exerted by the spring, k is the spring constant, and x is the distance the spring stretches. In this case, the force exerted by the spring is given by F = qVB, and the spring constant is k = 76 N/m. The charge of the particle is q = Ie, where I is the current and e is the charge of an electron. The velocity of the particle is V = L / t, where L is the length of the rod and t is the time it takes the particle to travel the length of the rod. Since the current is 14 A and the length of the rod is 0.77 m, the velocity of the particle is V = 0.77 m / (1 / 14 A) = 10.78 m/s. The strength of the magnetic field is 0.14 T, so the force exerted by the spring is F = (14 A)(1.60 x 10^-19 C)(10.78 m/s)(0.14 T) = 2.40 x 10^-17 N. Therefore, the distance each spring stretches is x = F / k = 2.40 x 10^-17 N / 76 N/m = 3.16 x 10^-19 meters.

where k is the Coulomb constant (8.99 x 10^9 N m^2/C^2), q1 and q2 are the charges, and r is the distance between them.

Plugging in the given values, we get:

2N = 8.99 x 10^9 N m^2/C^2 * (-3 x 10^-6 C)^2 / r^2

Solving for r, we get:

A magnetic field is induced in the rectangular loop as a result of the current in the wire. The plane is the intended target of this magnetic field.

As the current in the wire grows, the magnetic flux in the rectangular coil rises.

An emf and current are induced by Faraday's law.

Following is noted from Lenz's law:

The inwards growing flux is opposed by the generated current. Therefore, the induced current must flow counterclockwise in order to meet this.

The magnitude of the gravitational field of the planet depends on its mass and distance from the object being affected by it.

What is Gravitational field?

Gravitational field is a region of space where a mass or object experiences a force of gravity. It is caused by the presence of a massive object, such as a planet or star, which exerts a gravitational pull on other objects within its vicinity. The strength of the gravitational field is determined by the mass of the object and its distance from other objects.

The gravitational field of the planet at Point P can be calculated by using the equation,

g = G*M/r2

where G is the gravitational constant (6.67 x 10-11 Nm2/kg2), M is the mass of the planet (4 x 1026 kg), and r is the distance from the center of the planet to Point P (53,000 km).

Plugging in the values,

g = (6.67 x 10-11 Nm2/kg2) x (4 x 1026 kg) / (53,000 km)2

g = (6.67 x 10-11 Nm2/kg2) x (4 x 1026 kg) / (2.8409 x 1012 m2)

g = (6.67 x 10-11 Nm2/kg2) x (14.1636 x 1015 kg)
