Answers

Mining reclamation is the process in which mining companies restore land to its original contours and returns it back to its natural environmental structure that enables the rest of plants and some other vegetation to grow and reproduce. This helps in minimizing effects caused by mining in the environment.

Assignment: Ultrasound and Infrasound Research Exploration Ultrasound and infrasound are categories of sound with different frequencies. These categories of sound can be used for a variety of different applications. In this research assignment, you will take a look at the industrial applications of ultrasound and infrasound. Your essay should do the following things: • Define and describe in detail (and in your own words) ultrasound and infrasound • Describe how ultrasound and infrasound are used in specific industrial applications and provide detailed examples. When conducting your research, remember to gather information from multiple sources. Start your research by defining ultrasound and infrasound. Then find ideas about industrial applications. The essay should be about 350-450 words, which is 1-1.5 typed pages, double-spaced, using 12-pt. font. Check the rubric to review how you will be graded for this assignment. plz no funny answers

Answer:

Infrasound vs. Ultrasound: Infrasound is sound that is below the lower limit of human hearing, below 20 Hz, and ultrasound is above the upper limit of human hearing, above 20,000 Hz.  Individuals use infrasound - this recurrence run for checking seismic tremors and volcanoes, graphing rock and oil developments underneath the earth. Infrasound is described by a capacity to get around hindrances with little scattering.  

For instance, a few creatures, for example, whales, elephants and giraffes convey utilizing infrasound over significant distances. Torrential slides, volcanoes, seismic tremors, sea waves, water falls and meteors produce infrasonic waves. Symptomatic ultrasound, additionally called sonography or demonstrative clinical sonography, is an imaging technique that utilizes high-recurrence sound waves to create pictures of structures inside your body. The pictures can give important data to diagnosing and treating an assortment of ailments and conditions.

Infrasound is described by a capacity to get around hindrances with little scattering.  

For instance, creatures like whales, elephants and giraffes convey utilizing infrasound over significant distances. Torrential slides, volcanoes, seismic tremors, sea waves, waterfalls and meteors produce infrasonic waves.

Maria’s father started a fire in the fireplace. He crumpled some paper, lit a match, and soon the logs in the fireplace were burning. In this case, the stored chemical energy in the logs was changed intoA) electrical energy.

B) mechanical motion.

C) heat and light energy.

D) electrical and heat energy.

Answers

In this case the stored chemical energy in the logs was changed into heat and light energy. The correct option among all the options that are given in the question is the third option or option "C". The logs started burning and this burning released the light energy and the heat energy. I hope this answer helps you.

Which of the following absorbs the MOST heat energy?a. red objects
b. white objects
c. black objects
d. purple object

Answers

darker is warmer C. Black objects.
Black objects because light waves are attracted to darker objects.

gas stored in a tank at 273 k has a pressure of 50kpa. what happens to the volume when the pressure is decrease due to the added pressure

Answers


I can't think of any way that pressure can be decreased due to added pressure.

Be that as it may, and it certainly still is ...

No matter what you do to the pressure or the temperature of
the gas in that tank, the volume doesn't change.  Any sample
of gas always expands to fill the container in which it's confined. 
Its volume doesn't change until you either transfer it to another
container with different volume, or else change the volume of
the container it's in.

Can someone please help me with my physics homework?! A water skier has a mass off 68kg.

Calculate the resultant force acting on the water skier while accelerating.

Answers

Everybody is making something tough out of something easy.

Everybody knows the formula [ Force = (mass) x (acceleration) ].  Right ?

We're supposed to find the force on the skier when the skier is accelerating,
and it gives us the skier's mass.  So there you are !

Net force on the skier = (64 kg) x (the skier's acceleration).

It depends on the skier's acceleration, which we're not told.
More acceleration = the result of more net force.
More net force = the cause of more acceleration.

And that is absolutely everything that you can do with the information
that's given in this question.
