A heavy lab cart moves with kinetic energy kinit on a track and collides with a lighter lab cart that is initially at rest. the carts bounce off each other but the collision is not perfectly elastic, causing the two-cart system to lose kinetic energy klost . a student wonders if the fraction of kinetic energy lost from the two-cart system during the collision depends on the speed of the first cart before the collision and plans to perform an experiment.

Answers

The hypothesis; greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater is; Correct

What is the Hypothesis of the Collision?

In an Inelastic Collision, energy is not conserved . Now, the loss of energy could be in the form of friction, vibrational energy, sound, heat energy, e.tc.

Now, for example frictional energy is proportional to the velocity. The, the greater the velocity, the greater the loss of energy. This is also true about  vibrational energy, sound, heat energy, e.tc.

Thus, we can conclude that the hypothesis is correct.

Researchers designed an experiment to test the hypothesis that the evolution of coloration in lice is driven by birds. researchers transferred 25 lice from a random sample of lice obtained from wild‑caught rock pigeons to each individual in groups of black pigeons and white pigeons. half of the pigeons from each color group were fitted with a harmless mouthpiece that stopped the beaks from entirely closing. the mouthpiece prevented pigeons from removing lice but did not affect the pigeons’ ability to feed. each pigeon was isolated and kept in identical environmental conditions for temperature, humidity, and amount of light. the lice have a generation time of 24 days. the researchers observed the phenotypes of the lice over a period of four years.

Phenotypic variation in louse body color in a population of lice would make it difficult for the louse to be spotted and picked off any pigeon's feathers.

What is phenotypic variation?

Phenotypic variation can be defined as the difference (variability) in the observable characters or attributes (phenotypes) of each organism in a specific population.

Based on the research, it is very important for phenotypic variation to exist in louse body color among other individuals in a population of lice because there are two different colors of pigeons, which would make it difficult for the louse to be spotted and picked off their feathers.

can someone write a 1200 word essay for my explaining why plants are important i dont really know how to do this and i need help.

Answers

Answer:

Plants provide us with food, fiber, shelter, medicine, and fuel. The basic food for all organisms is

produced by green plants. In the process of food production, oxygen is released. This oxygen, which we

obtain from the air we breathe, is essential to life. The only source of food and oxygen are plants; no

animal alone can supply these. Shelter, in the form of wood for houses; and clothing, in the form of

cotton fibers, are obvious uses of plant materials. But we must not forget fuel, furniture, paper

products, certain medicines like aspirin, and many other products like perfume and chewing gum. To

these tangible aspects of the plant world we must also add the importance of beauty and relaxation

derived from plants. Since animals are surrounded by and dependent upon plants, the factors that

influence plant growth, structure, and distribution, affect the animal world as well.

Plant - Animal Relationships

Forests, lawns, streams, and marshes are all habitats that are easily recognized as unique biotic

communities. A community is a naturally occurring, interactive assemblage of plants and animals living

in the same environment. The interaction between plants and animals often exists out of the need for

food, protection, transportation, and reproduction. The different kinds of interaction possible between

organisms are extremely important in determining the abundance of species. If the interaction between

species is beneficial, it is described as mutualism. Some of the most complex mutualistic relationships

evolved between plants and pollinators. If the interaction proves disadvantageous, it is referred to as

competition. Commensal relationships, in which one species benefits and the other is unaffected, are

common between plants and animals. For example, when a bird builds a nest in a tree, the bird benefits

and the tree is (usually) unharmed. Other relationships may positively affect one population and be

detrimental to the other. Such relationships involve predation and parasitism. In predation, one

organism directly kills and consumes its prey. Parasitism differs in that parasites live on or in the prey,

but may not kill it outright. A good example of parasitism is mistletoe growing on a tree.

Ecosystems

An ecosystem is the biotic (living) and abiotic (nonliving) factors

of an ecological community considered together. Ecosystems contain

four components: the physical environment (abiotic), living things

(biotic), energy input and use, and nutrients that cycle between the

biotic and abiotic components. Based on this definition, ecosystems

can vary from large unbroken tracts of forest to small ephemeral ponds

to backyards.

Explanation:

Building sheep pens : darsh and darpan are fencing off a large rectangular area to build some temporary holding pens. to prep the males, females, and kids, they are separated into three smaller and equal-size pens partitioned

Answers

The larger rectangle will be a square with sides of 96 ft while the pens will have 96 ft of length and 31 ft of width

How to Maximize Area of rectangle?

The side lengths of the big rectangle are x and y and so we have the following expression for its area A:

A = x*y

This is tied to the constraint that the perimeter should not be larger than the available fencing , Thus;

2x + 2y = 384   (All the fencing is used to maximize the area)

y = (384 - 2x)/2

y = 192 - x

Put 192 - x for y in A to get;

A = x(192 - x)

A = 192x - x²

Completing the square gives;

A = 9216 - (x - 96)²

Thus;

A is maximum at;

x - 96 = 0

x = 96 ft

y = 192 - 96

y = 96 ft

Then since we maximised the area of the bigger rectangle , we have maximised the area of the smaller pens. The dimensions will be;

x_small = 96 ft /3

x_small = 31 ft

y_small = 96 ft

Complete question is;

Building sheep pens: It's time to drench the sheep again, so Chance and Chelsea-Lou are fencing off a large rectangular area to build some temporary holding pens. To prep the males, females, and lambs, they are separated into three smaller and equal-size pens partitioned within the large rectangle.

Answers

The most accurate statement concerning any legal challenge is that pay difference is unlawful unless Midwest can establish some significant difference between Zone A and Zone B.

Which legislation guided this practice?

Equal Pay Act of 1963 was the legislation that stated that both men and women must earn the same salary for similar jobs.

The legislation prohibited discimination of gender when establishing a person's salary.

However, there is an exception which is if work carried out in Zone A is much more demanding, challenging, difficult, important or relevant than the work carried out in Zone B, then, the company will be vindicated from any legal matter.

Thereforel the Option B is correct.

Missing options "a) The pay difference is not unlawful and cannot be challenged because there is less than a 10% pay difference between what Midwest pays John and Jane.b) The pay difference is unlawful, unless Midwest can establish some significant difference between Zone A and Zone B.c) The pay difference is not unlawful and cannot be challenged in this instance because the "seniority" defense allows for different pay for men and women even though they may be performing "substantially the same job".d) The pay difference is unlawful, not because of the gender difference between John and Jane, but because Midwest is violating its own stated pay policy.
