4. Two objects were lifted by a machine. One object had a mass of 2 kilograms, and was lifted a t a speed of 2 m/sec. The other had a mass of 4 kilograms and was lifted at a rate of 3 m/sec.

Question a. Which object had more kinetic energy while it was being lifted?

Question b. Which object had more potential energy when it was lifted to a distance of 10 meters? Show your calculation.

Answers

Explanation:

a) Case1, by the formula, ke=½mv².

m=2kg, v=2m/s

ke = ½×2×2² = 4J

Case2, by the formula, ke=½mv².

m=4kg, v=3m/s

ke = ½×4×3² = 18J

therefore, the second object has more kinetic energy.

b) Case1, by the formula, pe = mgh

m=2kg, g=9.8m/s²(not given)(can consider 10m/s² when given), h= 10m

Pe1(write 1 in subscript) = 2×9.8×10= 196J.

Case2, by the formula, pe = mgh

m=4kg, g=9.8m/s²(not given)(can consider 10m/s² when given), h= 10m

Pe2(write 2 in subscript) = 4×9.8×10= 392J.

so, the object 2 has more potential energy.

These bright colors serve as a warning to predators: "Don't consume me; because it is poisonous." In this consideration, frogs aren't overhead bluffing.

Some nonpoisonous species of frogs have assumed the colors of poison dart frogs to trick vampires into offering them an expansive berth they don't earn.

This technique is prompted by melanin, a dark pigment. These frogs usually combine in with their surroundings and their skin functions as camouflage.

what determines how closely related 2 species are?

Answers

Answer:

Before: (Darwin did) Physical features and behavior

Now:

DNA Testing

Explanation:

Similarities are often easy to see when one looks at two organisms that evolved from a common ancestor, and until recently, looking at physical features and behavior was the only way to determine how closely related two organisms are. However, now scientists can also analyze DNA to discover how closely organisms are related. Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms. This method can also help when looks are deceptive. One example of looks being deceptive is: The bat and the crow both have wings, and the squirrel does not. From this, one may think that bats and crows are more closely related than bats and squirrels, while the opposite is indeed the case.

in what generation does this population reach its carrying capacity

Answers

Answer:

The logistic population growth happens as the growth rate declines as the population exceeds the carrying power. The highest number of people in a community that the ecosystem can sustain is carrying capacity.

Explanation:

A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.

What is carrying capacity?

The carrying capacity of a population is the maximum number of individuals that can be supported by a particular environment over a given time period. A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.

For example, if a population of animals is introduced to a new habitat with abundant resources, it may be able to grow rapidly and reach its carrying capacity relatively quickly. On the other hand, if the population is facing competition from other species or is subjected to predation or other limiting factors, it may take longer for the population to reach its carrying capacity.

It's important to note that the carrying capacity of a population is not a fixed value, and it can change over time due to changes in the environment or the population's own characteristics. For example, if the population grows to a size that exceeds the carrying capacity of its environment, it may begin to experience negative impacts such as resource depletion, disease outbreaks, or other factors that can reduce its size and bring it back down to the carrying capacity.
