Scientific Method
The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

How is mathematics used in evaluating data?
Scientists can evaluate the mathematical calculations of others.
What are the Common environmental problems that can solve by scientific method?
avoid doing unnecessary things that will bring problems to our environment
Is dependent variable the variable that can't change?
Not exactly sure what you mean by "can't change."
However, I if I do understand you correctly, the dependent variable CAN change. The dependent variable will change according to the independent variable's value and overall effect.
For example, in an experiment involving water's effect on plants, the dependent variable may be the height of the plant or the glucose produced. Based on the amount of the independent variable (represented on the x axis of a data graph), the dependent variable will increase or decrease. In this case, both dependent values (glucose and height) would probably increase.
Will a nail get rusted when coated with vaseline and put in water?
yup........
vaseline is a petroleum gel and it has low density than water. So the vaseline came up on the water when the temperature changes. after some days when the vasline complitly removed the nail become rest ok for more details:)9633977254
What problems cannot be solved by scientific method?
Oh ye of little faith, walk the path of scientific inquiry as I have and you will only get close. Because it still takes a leap of faith. The innocent children and lesser intellects who believe in God are wiser than you who does not.
The beginning of wisdom is belief and faith in God. Put aside your pedantic quest to measure something that is beyond measuring. Open your mind and heart to the TRUTH.
Answer:
The scientific method, hard work and human intellect will eventually lead us to any answer we want. No other approach has advanced human health and well being as much as science.
What 2 ways do they have predicted the beginning of the universe?
The big bang or God created it. Mostly the big bang is the scientific reason and God is the religious reason.
What is the hypothesis for Paintball Ballistics?
The ballistics are similar to that of a musket ball. Paintballs are not accurate at long ranges, and have a tendency to swerve or dive.
At speeds above approx. 350 feet per second they also tend to wobble (i.e. jump around in seemingly random directions while in flight).
The subject of bioethics deals with questions about what people ought to do with their knowledge of Biology.
What instrument measures luminous intensity or flux?
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
What are the two types of data in scientific method?
Qualitative (things you can describe, like categories: gender or sport, variables like sm, m, and lg, or attitudes: agree/disagree, etc) and quantitative: things you can measure and report in numbers (like mass or volume)
A hypothesis is the correct explanation for some scientific question?
no a hypothesis is your guess of what the outcome is going to be in your experiment. For example. My experiment's question is to see what happens when I mix salt with water. My Hypothesis is the salt will float. Now the correct outcome is the salt sinked. I hope I helped you.
Where a major earthquake has happened in the past but not in a while is called a seismic?
Seismic gap.
What are the different scientific methods?
The principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to demonstrate the truth or falseness of the hypothesis, and a conclusion that validates or modifies the hypothesis.
How are sedimentary rocks form?
Sedimentary rocks can be formed in various ways, and are classified by the method of formation or content. Broadly, sedimentary rock is classified as being clastic, organic, or chemical. Following are the three types and how they are formed.
Clastic sedimentary rock:
The majority of sedimentary rock on Earth is formed from particles of pre-existing rocks. This route begins with the weathering and erosion of sedimentary, igneous, or metamorphic rocks. Through these processes, larger rock is broken up into smaller particles which are transported by moving water, ice, gravity or wind, and deposited at the bottom of a lake, a river delta, an ocean, or similar location where further movement is restricted or slowed down. The rock particles can range in size from boulders to clay particles less than .002 mm in diameter. If these rock particles are covered by additional particles, eventually the weight from above will start the process of lithification. Lithification is the compaction and cementing together of sediment particles which form rock. Compaction squeezes out the fluids and space that exist between the particles, and cementation results when minerals form from the migrating solution. Once cementation occurs, the new sedimentary rock has been formed. Rocks formed in this manner include sandstone, shale, mudstone, breccia, and conglomerate.
Organic sedimentary rock:
Chalk and other fossiliferous limestones are composed of the skeletons of marine organisms. Coal is composed of vegetation that originated and was deposited in swampy and marshy waterlogged soils which prevented their full decay after their death. As their remains piled up and were covered by more and more deposits, they were compacted and cemented in the same manner as clastic rock.
Chemical sedimentary rock:
Sedimentary rock can also form when minerals in a body of water have so saturated the water that they precipitate out, like a cloud that is so full of moisture that it pours out rain. Some limestones are formed in this manner as the mineral calcite precipitates out of a saturated solution and undergoes the process of compaction and cementation. The supersaturated solutions can also be caused by evaporation of a body of water high in mineral solution content. As the water evaporates, the mineral percentage of the remaining solution becomes higher and higher, until the mineral crystallizes. Rocks such as rock salt and rock gypsum are formed in this manner.
It is formed by the sedimentation of material at the Earth's surface and also in the bodies of water.
Sedimentary rocks are formed at the bottom of lakes after being compressed over a long period of time...
Sedimentary rocks are formed mainly through a proccess called Diagnesis. Diagnesis can be defined as the combined process of gradual and contineous accumulation, stratification, compactation, sedimentation, cementation, and lithification of transported and deposited debrises, detrituses, regoliths and other earths disintegrated materials, to form sedimentary rocks over a long period of time. Sedimentary rocks are created or formed out of virtually anything that exists around, which can be moved either by wind, water, glacier or waves and deposited in a specific place over and over again. They are rocks that tends to "germinate" by addition of materials/matter in stratas/layers and then the materials hardens, glues up/cements to themselves and hardens with time.
Sand and other particles are buried, compacted, and cemented together.
why using k map the rule is that the extra overlapping should not done .But in some case this may cause the problem in combinational logic that problem are called 'Hazards' and it can only overcome by using overlapping of k-map.

x3 can mean a lot of things, for example:
In math is can mean: the variable x equals 3.
In BMW sportcars: X3 is a model of car with a meaning often known only to the car company.
On mechanical drawings: x3 can mean times 3
How does water enter a submarine?
Water enters the submarine by entering through the butthole and leaving from the propellers
What is the purpose of using scientific method in psychological experiments?
It is used to avoid common problems that occur in the absence of using the scientific method.
How do effluent treatment plants and water treatment plants work?
A water treatment plant will usually take water from a dammed river. The water is then filtered and purified till it is potable (that is, drinkable). Depending on the quality of the water it may have to be disinfected with chlorine or other chemicals to make it safe for use.
An effluent treatment plant takes sewage runoff from toilets, factories, stormwater drains and other sources.
Screening: First the effluent is screened to remove any solids (cans, plastic, condoms, tampons etc). It then moves through a tank slowly enough so that sand, stones and rock sink to the bottom where they can be removed before the mixture starts going through pumps. (The sand is usually sent to landfill.)
Primary Treatment: The sewage then flows slowly through large tanks. Here the sludge sinks to the bottom and the oil and grease rise to the top. The sludge and the oils are then removed.
Secondary Treatment: The remaining mixture is treated using aerobic biological processes. Air is pumped through to encourage bacteria and protozoas to break down the contaminants.
Tertiary Treatment: Finally the treated water is given a final processing before it is discharged into a river, lake or ocean. Any one or more of the following methods are used:
- filtration (through sands)
- lagooning (stored in large man-made lagoons where reeds and other plants assist)
- constructed wetlands (rather like lagooning, using reedbeds and other similar methods)
- nutrient removal (to remove nitrogen and phosphorus)
- disinfection
Any metal which can get oxidised in the presence of oxygen from the air and water.
How does water enter the submarine?
Water enters the submarine by letting water out not into its ballast tanks it enters from the flagura to the magura.
Using the scientific method Can a lit candle in a sealed glass die by loneliness?
No. It extinguishes from lack of oxygen.
