Explanation:

Water purification methods are Distillation Ultraviolet Disinfection Membrane Filtration, and Waste disposal methods are Incineration and Landfilling.

What is water purification?

Water purification is the removal of contaminants from water in order to make it safe for human consumption, irrigation, or other uses.

Filtration, distillation, chlorination, ultraviolet (UV) disinfection, and reverse osmosis are all common methods of water purification.

The method used is determined by the quality of the source water, the intended use of the treated water, and other factors such as cost and resource availability.

The process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from contaminated water is known as water purification.

Methods of water purification:

DistillationDisinfection with Ultraviolet LightFiltration by Membrane

Methods of waste disposal:

If a bolt is broken off flush with a surface, and the bolt is large enough in diameter, then you may be able to use a small ____________ to turn the bolt by tapping on the outside diameter of the bolt, but in the reverse direction. Select one: a. Piston b. Center punch c. Both A and B d. Neither A nor B

Answers

"c" (and any subsequent words) was ignored because we limit queries to 32 words.

If a bolt is broken off flush with a surface, and the bolt is large enough in diameter, then you may be able to use a small Piston and Centre punch to turn the bolt by tapping on the outside diameter of the bolt, but in the reverse direction. Hence, option C is correct.

What is diameter?

Any straight line passing through the center of a circle and joining two points on its rim. The geometrical length of such a line. The maximum distance in metric space that can exist between any two points.

The diameter of a circle is the length of a straight line across its center. An example of diameter is the width of a line across the center of a pie.

The classic definition of Pi is based on the ratio of the circumference to the diameter of a circle (). The circumference of a circle is its length or diameter. However, the diameter is a straight line that connects a point on one end of the circle to a point on the other.

Thus, option C is correct.

A train that runs on a gearbox system is a mechanism employed for motion. The movement of the gears is transferred inside the teeth. Three or some extra gears are coordinated to produce a train with a gearbox system. When you want to take your train to the hilly areas, you utilize a gear train that produces more torque (conversion energy) but, reciprocal it for, less speed.

Biomechanics informs runners on the best form for the greatest speed and lowest risk of injury. There are several websites and videos dedicated to instructing runners how to run effectively with correct biomechanics.

For this project, you are to measure and compare running speed using proper biomechanics versus running speed while not using proper biomechanics. Present your findings in a 300 word paper.

The experiment: Measure a 100-meter straight line. Research the biomechanics of running.

1st Attempt: Either you or another individual run the 100-meter as fast as possible without applying biomechanics. Have someone time this run using a timer or stopwatch.

2nd Attempt: The same person runs the 100 meters as fast as possible, applying the biomechanics information provided from one of the websites above or one you find on your own. Have someone time this run using a timer or stopwatch.

Equipment needed: stopwatch or timer

Your paper should include:
a title;
information on the biomechanics of running;
results of the experiment (timed run with and without applying biomechanics information);
discussion of the results of your experiment;
what elements of STEM were applied to improve running;
at least 300 words.
a reference page.
Your project should be:

well-organized;
contain appropriate language;
contain proper grammar, punctuation, and spelling;
contain information from credible sources;
contain a reference page listing all sources used for the assignment.

Answer:

i cant help sorry

Explanation:

Answer:

Today we are doing a project on biomechanics. For this project we are going to use stem variables with running to test the difference in this project.Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, using the methods of mechanics. The objective of this assignment is to record someone running 100 m and recording another person running the same distance but with another variable. I'm kind of thinking that the second person would wear leg weights for the second 100 m but that is just a thought.

So the first part is measuring the 100m test. It  was not that hard and it did take a little time but in the end we got it from the start of my  block to the middle of the block. After measuring then came the second step : thinking of the variable for the second person. So when i thought about this for the first time i did not think what variable to add and then when i actually thought that i could make this a little harder on the second person just for the test and a little fun and decided that the second person was going to wear leg weights while running the 100 m. after that i got a stopwatch and two friends to do this project for me.  The faster friend had leg weights and the slower friend did not have any.i did this to improve the slower friend  I told the first person that he was going to run 100 m. after that he started running and I recorded the time. It was 28 seconds. Then i told the second friend to also run the 100m but i also told him that he was going to wear leg weights. After that it took him a long 35 seconds including breaks to finish his 100 m.

An air mass usually forms in an area of____.

a. low pressure because its stable
b. low pressure because its unstable
c. high pressure because its unstable
d. high pressure because its stable

Answers

I think it’s b hopefully it is
D. High pressure because it’s stable

Explanation:

Air mass is volume of air which has stable temperature, humidity and pressure horizontally. Over time, each air mass acquires properties of the region by residing over same part of a surface

Areas of low pressure and high pressure occur where there is warm air and cold air rises up and cold air takes its place. Warm air has low density and pressure therefore, sinks to the bottom. This is a stable condition. The movement of air mass is responsible for maintenance of temperature conditions on Earth.
