What is the frequency of a wave that has a period of 0.5 seconds
Answer:
Explanation:Each drum must endure for one-half a second, so the period is 0.5 s. If the woodpecker drums upon a tree 4 times in one second, then the frequency is 4 Hz; each drum must endure for one-fourth a second, so the period is 0.25 s.

why do scientists often use computers to run simulations
Answer:
These days, simulations are often run on computers. Scientists use simulations to answer questions, see how complex systems work, test ideas, and make predictions.
The rules that explain how the universe works, the laws of physics, have to be imported into the computer. This information is called a model.

Which of these is a correct statement about pH?
The pH of a solution increases as its acidity increases.
O The pH of a basic or alkaline solution is less than that of an acidic solution.
O As the concentration of H increases in a solution, the pH decreases.
O A solution to which HCl has been added will have a greater pH than a solution
to which NaOH has been added.
O Each number on the pH scale represents an increase of 108.
Question 3
Answer:
your correct answer is 3 ok
The pH of a solution increases as its acidity increases 3) A solution to which HCl has been added will have a greater pH than a solution to which NaOH has been added.
While the acidity of an answer will increase does the pH increase?As a solution gets greater acidic (as [H+] will increase), the pH decreases. As an answer receives greater basic (better [OH-]), the pH increases. Because the pH of a solution decreases through one pH unit, the attention of H+ will increase by way of ten times.
The logarithmic scale of pH method that as pH will increase, the H+ attention will decrease through the power of 10. Therefore at a pH of zero, H+ has an awareness of 1 M.
Decrease pH variety approach stronger acid, higher pH number approach the stronger base. It may be a bit difficult, but the decrease the pH of a substance, the stronger an acid it's miles.

When our body gets too hot, we begin to sweat. When sweat evaporates, thermal energy is transferred to the air outside our body and our body temperature drops. What characteristic of life does this represent?
Answer:
This involves the transfer of heat from one object to another, with no physical contact involved.
Explanation:
The sun transfers heat to the earth through radiation. The last process of heat loss is evaporation.
A monomer is to a polymer, like a____? A) word is to a sentence B) Lego block is to a Lego castle C) tree is to a forest D) All of the above
Please help I'm taking a test
A monomer is a polymer like a word is to a sentence, a Lego block is to a Lego castle, and a tree is to a forest. The correct option is D) All of the above.
What are polymers?Polymers are chains of monomers. Many monomers join together to form polymers. Monomers are single units of something. Now many polymers are made up of the same types of monomers, they are called homopolymers.
Herteropolymers are those polymers that are made up of different units of monomers. A group of words makes a sentence. Lego is a piece of plastic block that made a Lego castle or other things. Trees are the monomers unit of a forest because many trees made a forest. So all these are equivalent to what a monomer is to a polymer.
Thus, the correct option is D) All of the above.

Fishing is a major part of many Caribbean economies. The yellowtail snapper and Nassau grouper are important food fishes. However, a lack of adequate regulation has led to overfishing in many areas and consequent damage to reefs.
When grouper fishing is set to 70% what happens to the population of other fish populations in the reef?
Question 1 options:
The lack of grouper fish in the food web caused a spike in the snappers that are usually eaten by the groupers.
Since there were hardly any grouper left as a result, the snapper population also decreased amongst the reef community.
All the other fish populations in the gizmo increased as a result of the fishing favoring the grouper.
Answer:
The lack of grouper fish in the food web caused a spike in the snappers that are usually eaten by the groupers.
Explanation: because fish. (i did the test btw so i know this is correct ;)
When grouper fishing is set to 70%. The lack of grouper fish in the food web caused a spike in the snappers that are usually eaten by the groupers. The correct option is A.
What is fishing?Fishing is a technique to catch fish and other water organism for selling and food purposes. Here the topic is overfishing, which means the over-catching of fish, which disbalances the ecosystem.
In Caribbean economies, fishing is an important act. There are two main fish, groper, and snapper. But due to the deregulation of catching fishes, the grouper fishes are killing more than the snapper fishes. So this would cause a decrease in the population of groupers.
Thus, the correct option is A. The lack of grouper fish in the food web caused a spike in the snappers that are usually eaten by the groupers.

Why do some scientists believe that RNA, rather than DNA, was the first genetic material?
RNA can replicate more accurately than DNA.
RNA contains uracil in place of thymine.
All of the protocells on early Earth contained RNA.
RNA has both information storage and catalytic properties.
The correct answer as to why some scientists believe that RNA, rather than DNA, was the first genetic material would be that RNA has both information storage and catalytic properties.
Other options are cannot be correct because:
RNA cannot replicate itself unless it is in a living host.RNA containing Uracil instead of Thymine has no effect on being the first genetic material or otherwise.There is no clear evidence to show that all of the protocells on early Earth contained RNAThe fact that RNA has the capacity to store information as well as catalyze important biological processes made it a plausible candidate as the first genetic material. DNA has the capacity to store information but lacks catalytic properties, unlike RNA.

A Congressional Budget Office (CBO) estimate put the bill's cost at $182 million over five years when the bill was first introduced in 2016. The policy of the U.S government includes strong support for research into and preparedness for the effects of space weather. Does the government's policy match its actions? Does it match the seriousness of the situation? What are the consequences?
During the Obama Administration, a significant step was taken by the administration in order to prepare critical technology and infrastructure in order to curtail the risk of the space weather.
Space weather simply means the effects that emissions from the sun, have on the space environment. Space weather can have a negative impact on the infrastructures that are essential to the economy like water supply, electrical power, transportation, health care, etc.Space weather is a concern now due to the fact that the modern technology depends on signals and these are vulnerable and can be affected by space weather. The Executive Order was put in place to help in the reduction of economic loss and saving of lives of the people. The policy of the government matches it actions. In order to support the space weather research, it should be noted that National Aeronautics and Space Administration[NASA] keeps an eye and observes the space environment often by using solar observatories and studying the solar atmosphere, magnetic fields etc. and other bodies that surround the Earth.Read related link on:
