How can you increase kinetic energy?|
Darya [45]

                                        <u>Answer and Explanation</u>

<u>__________________________________________________________</u>

According to <em>Sciencing,</em>

<h2><em>Translational Kinetic Energy </em></h2>

<em>Translational kinetic energy is the energy of motion in a straight direction -- think of it as the energy of a car driving down the street. Kinetic energy is a function of the object's mass and its velocity. More specifically, translational kinetic energy can be described as one-half times the mass times the square of the object's velocity: 1/2mv^2. </em>

<em> __________________________________________________________</em>

<h2><em>Increasing Translational Kinetic Energy </em></h2>

<em>Because the translational kinetic energy formula consists of only two variables, mass, and velocity, increasing one of those properties is the only way to increase an object's translational kinetic energy. Increases to mass and velocity, however, do not have the same impact. Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity. </em>

<em> __________________________________________________________</em>

<h2><em>Rotational Kinetic Energy </em></h2>

<em>Rotational kinetic energy describes the energy of an object rotating around a center of gravity -- for example, a rider on a Ferris wheel. In this case, kinetic energy is still a function of mass and velocity, but the terms used are slightly different to account for the movement in a circular direction. Rotational kinetic energy applies the same equation, except the mass term is replaced by a variable known as the "moment of inertia," (I), while the velocity term is replaced by the object's "angular velocity," (w) -- 1/2Iw^2. </em>

<em> __________________________________________________________</em>

<h2><em>Increasing Rotational Kinetic Energy </em></h2>

<em>As with translational kinetic energy, increasing energy is a matter of increasing mass and velocity. The "moment of inertia" is equal to an object's mass times the square of its distance from the center of rotation, so it can be increased by either increasing the object's mass or moving it farther from the center of rotation -- simply build a bigger Ferris wheel. Alternatively, you can increase the kinetic energy by increasing the angular velocity, which means simply increasing the speed at which the object rotates around the center of rotation.</em>

Can the use of badger control (including culling) be justified in the
bonufazy [111]

Answer:

no. badger vaccination is better

Explanation:

spreading mostly happens cattle to cattle

"killing badgers will not solve the problem. Badgers are not the primary cause of the spread of bTB in cattle: the primary route of infection is cattle-to-cattle contact[2]. The Government's badger cull is flying in the face of science. It should be putting more resources into speeding up the development of an effective cattle vaccine, amongst other measures"

Which best describes independent assortment?
bekas [8.4K]

Answer:

In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.

Explanation:

In diploid (2n) organisms, the homologous chromosomes are the two copies of each chromosome, where one of these homologs is the chromosome from the mother, while the second one is from the father. During metaphase I, the homologous pairs of chromosomes pair together at the middle of the cell. The law of independent assortment, also known as or Mendel's Second Law, states that homologous chromosomes line up in random orientations at the metaphase plate during this period (metaphase I).

The cytoskeleton and extracellular matrix help to support the cell’s structure. The cytoskeleton can be compared to which of the
lys-0071 [83]
The answer to your question is either drawbridge or scaffolding. I want to go with drawbridge because it has support and stands of for itself, so its similar to a stucture if that makes sense.
