The edges of a meander are where speed and turbulence are highest. This occurs because the stream velocity will be at its peak when the meander of a river or channel is at its deepest point, causing the turbulence to be at its highest as well.

The following characteristics of turbulence include: All turbulent flows are very erratic. Due of this, statistical approaches rather than deterministic ones are typically used to solve turbulence problems.

Flow velocity increments, or the difference in flow velocity between two points separated by a vector r, are a common method of investigating turbulent flow velocity fields (since the flow r's modulus is the only factor affecting velocity increase. )

Answer:

It's all about the conduction between the pan and the cookies.

Explanation:

The cookies in the middle of the pan are not going to be cooked as much as the cookies touching both the bottom of the pan and the side of the pan due to the level of heat being given to those outside cookies. Lets try an example:

Lets say you're in a car in the middle of summer. You and your sibling sit on opposite sides of your other sibling, who is sitting in the middle seat. You and your other sibling are pressed up against the door of the car, making you heat up quicker since not only is it hot in the car, the sun is also on you. Meanwhile your other sibling isn't getting as much heat (but is still warm).

I hope this was able to help! There weren't any answers listed, so it may be the following:

- Conduction of heat

- Transfer of heat

- The pan heating up more of the cookie

- The conversion of more heat energy to the outside cookies

The tragedy of the commons is an economic problem that occurs when individuals or groups use a shared resource for their benefit without considering the well-being of the group as a whole.

The problem arises because each individual benefits from using the resource, but the cost of overuse is spread across the group.

The tragedy of the commons can be avoided by establishing rules and regulations that limit the use of shared resources. This can be done through privatization or through government intervention.

The net electric field at the center of the square is directed along the positive y-axis and has a magnitude of kq/2^3/2.

We can choose a coordinate system with origin at center of square, so that the position vectors of the charges are:

\(r1 = (1,1) \\r2 = (-1,1) \\r3 = (1,-1)\)

The electric field at the center of square due to each charge can be calculated using Coulomb's law:

\(E1 = kq(r1 - r)/(r1 - r)^3 \\E2 = kq(r2 - r)/(r2 - r)^3\\E3 = kq(r3 - r)/(r3 - r)^3\)

Since the charges are all of the same magnitude q, the electric fields have the same magnitude:

|E1| = |E2| = |E3| = kq/2^3/2

To find the direction of the electric field at the center of the square, we need to add the three electric fields vectorially:

\(E = E1 + E2 + E3\)

Using vector addition:

\(E = kq/2^3/2 [(1,1)/(2^1/2) - (1,-1)/(2^1/2) - (-1,1)/(2^1/2)]\)

\(E = kq/2^3/2 (0,2)\)

Answer:

6000n

Explanation:

You can change the volume, pressure, or temperature of a gas.

Change the volume of a gas to raise or lower the temperature. As the temperature increases, the gas expands and increases in volume. Conversely, as the temperature decreases, the volume of the gas decreases. As the temperature increases, the volume of the gas increases. Conversely increasing the pressure will decrease the volume of the gas.

Reducing the gas volume increases the gas pressure. An example of this is when gas is trapped inside a cylinder by a piston. When the piston is pushed in, the volume occupied by the gas decreases, so there is less room for gas particles to move. The relationship between pressure and volume Boyle's Law. As the pressure of a gas increases the gas particles are pushed together thus decreasing the volume of the gas.

The scale will read 8,996 N during the acceleration.

The force applied to the woman by the scale is the sum of her weight and the weight of the elevator and scale (66.0 kg + 784 kg = 850.0 kg). This can be calculated using the equation

Force = Mass x Acceleration (F = ma).

The acceleration is given by the force applied (9030 N) divided by the total mass (850.0 kg), which gives a result of 10.6 m/s2.

We then multiply this acceleration by the mass of the woman (66.0 kg) to get the force applied to the woman by the scale, which is 696 N.

We then add this to the weight of the elevator and scale (784 kg) to get the total force that the scale reads, which is 8,996 N.

We will determine the final speed as follows:

So, superman's final velocity is approximately 201 m/s.

[In this case superman's initial velocity is a datapoint that is not necessary]

An object's momentum is a measure of its motion, defined as the product of its mass and its velocity. This means that an object with a large mass moving at a high velocity will have greater momentum than an object with a smaller mass moving at a slower velocity.

The momentum of an object is a vector quantity, which means it has both magnitude and direction. The direction of an object's momentum is the same as the direction of its velocity. This means that if an object is moving north, its momentum is also northward. Momentum is an important concept in physics, particularly in the study of collisions and interactions between objects.

In these situations, the total momentum of a system is conserved, meaning that the sum of the momenta of all objects involved remains constant before and after the interaction. This principle is known as the law of conservation of momentum and is crucial for understanding the behavior of objects in motion.

The partial pressures of gases in cells of systemic tissues result from the process of gas exchange and cellular respiration.

The partial pressures of gases in cells of systemic tissues result from the process of gas exchange and cellular respiration.

During cellular respiration, cells metabolize glucose and produce carbon dioxide (CO2) as a waste product. At the same time, oxygen (O2) is required for cellular respiration to occur.

The partial pressure of a gas refers to the pressure exerted by that gas in a mixture. In systemic tissues, oxygen diffuses from the bloodstream into the cells, where it is consumed in cellular respiration. As a result, the partial pressure of oxygen decreases in the cells.

Conversely, carbon dioxide produced by cellular respiration diffuses out of the cells into the bloodstream, leading to an increase in the partial pressure of carbon dioxide in the cells.

The partial pressures of gases in cells of systemic tissues are determined by the balance between gas diffusion and the metabolic activities of the cells. This allows for efficient gas exchange and the supply of oxygen for cellular respiration while removing carbon dioxide waste from the cells.

The velocity of the cannonball must be 65.7 m/s to the right.

According to the law of conservation of momentum, the total momentum before firing must be equal to the total momentum after firing. The momentum of an object is given by its mass multiplied by its velocity.

Let's denote the velocity of the cannonball as v and use positive values for motion to the right and negative values for motion to the left. Since the cannon is initially stationary, its velocity is 0 m/s.

Using the conservation of momentum, we can write the equation:

(219 kg + 20 kg) × 0 m/s = 219 kg × (-6.2 m/s) + 20 kg × v

Simplifying the equation, we get:

0 = -1357.8 kg·m/s + 20 kg × v

Rearranging the equation to solve for v, we find:

v = 1357.8 kg·m/s / 20 kg

v ≈ 67.89 m/s

Since we assumed positive values for the motion to the right, the velocity of the cannonball is approximately 65.7 m/s to the right.

The true strain at the onset of necking can be obtained from the Hollomon equation as follows: true strain = (K/S)^(1/n).

Here, K is the strength coefficient, S is the stress, and n is the strain hardening exponent. Thus, given the values of these parameters, we can calculate the true strain at the onset of necking.

The Hollomon equation is a mathematical expression for the true stress-true strain curve that relates the true stress to the true strain in a material. It is expressed as follows: true stress = K(true strain)^n. Here, K is the strength coefficient and n is the strain hardening exponent.

The true strain at the onset of necking is the strain at which the material starts to deform plastically instead of elastically. This can be obtained from the Hollomon equation by rearranging it to the form true strain = (K/S)^(1/n).
