What is the function of research articles in scientific journals?
it allows scientists to share knowledge
Why are experiments done over and over?
So they can get an acurate result, from doing it over and over, you are letting yourself see all the different answers, and the one that is most acurate
Difference between Duracel and Energizer?
Energizer batteries are used exclusively to power the Energizer Bunny, which keeps going and going and going...
Qualitative and quantitative reseach?
Quantitative research is generally more related to physics and "measuring" results which can often be expressed as numbers, and are reproducible using the scientific method:
"45% of the people tested prefer product A, 37% prefer product C"
"light travels at 2.997m/s"
Qualitative research is more related to things that cannot be easily measured or proven, such as why people do certain things.

Is it possible to pull a table cloth out from under dishes without breaking them?
Yes. If you do it as fast as you possibly can, because of physics, the dishes will remain unscathed.
What type of energy do people get from the food they eat?
we get chemical energy from food.but they are expressed in calories.two persons misread the questions i think.ok,see about the chemical energy.
The energy held in the covalent bonds between atoms in a molecule is called chemical energy. Every bond has a certain amount of energy. To break the bond requires energy -- in chemical language it is called endothermic. These broken bonds then join together to create new molecules, and in the process release heat -- chemists call this exothermic. If the total heat given out is more than the heat taken in then the whole reaction is called exothermic, and the chemicals get hot.
The burning of methane in oxygen is an example of this. If the heat taken in is more than the heat given out then the whole reaction is endothermic and the chemicals get cold. Combining carbon and hydrogen to make methane is an example. We rarely meet such reactions in every day life. They happen in living cells, the energy being supplied by sunlight or some other source.
ATP is the molecule used by life to carry chemical energy. The bond between two of its phosphate groups carries a lot of energy because both phosphates have negative electric charge.
What will happen if we don't start recycleing?
We will be walking in mounds of dirt and species of animals will die.
Do all plastic shopping bags carry the same amount of weight?
Normally yes, but some might be made of recycled plastic or thinner plastic than usual, and some may be of thick coloured plastic, and if the weight is too heavy or there are protruding corners or edges, then the bag might not carry the same weight as others.
So it really depends on the make of the bag.
I hope this answers your question.
Well...first you need to get a motor(brushless, about £15 pounds on eBay), li-po batterys (2-3 cell) (£10 on eBay) and a receiver with crystal. you will also need a servo(s). the design is up to you! the shassy could be made out of plexiglass to PVC to baulsa wood. anything really.
How many decibels is a shotgun?
It depends really how close that shot explodes to you ear. The more far away the better. Avoid soundpressure levels of more than 120 dB. That hurts.

How does hydroelectricity harm us?
by the rain and by not going green even by littering on ground and the most is by gases in the air
What is the definition of 'instrument sensitivity' in physics?
Instrument sensitivity in physics refers to the ability of an instrument to detect small changes in the quantity being measured. A highly sensitive instrument can accurately measure even tiny variations in the parameter of interest. Sensitivity is often expressed as the smallest change in input that the instrument can detect.
What are the uses of hydroelectric energy today?
Hydroelectric energy is electricity and is put on the national grid for use by the public. It is used for pretty much every modern process of anything, in some way or another.
How can microscopes help us do an experiment?
Microscope will help us to view/see even very minute details of anything being experimented.
depends on how wet the spunge was because the more water soaked in the sponge the heavier it is and that meaning how fast it will fall
How do you stop a tennis ball from bouncing using the cold?
You can stop a tennis ball from bouncing by placing it in a freezer or exposing it to very cold temperatures. The cold will reduce the elasticity of the ball's rubber material, causing it to become stiff and unable to bounce.
Approaches to Pricing Services?
Cost - Based Pricing
• Price = Direct costs + Overhead costs + Profit margin.
• ( Direct costs involve materials and labour that are associated with delivering the service, overhead costs are a share of fixed costs, and the profit margin is a %age of full costs( direct + overhead)
Problems with cost - based pricing
• Costs are difficult to trace.
• Labour is more difficult to price than materials.
• Costs may not equal the value the customers perceive the services are worth
• Cost - based pricing is used in construction, engineering, advertising.
• Hourly fee usually charged for consultancy or by lawyers.
Competition- based pricing
Focuses on the prices charged by other firms in the same industry and market. This approach usually works where services are standard (eg dry- cleaning) or where there are oligopolies (a few large service providers, as in airlines)
Problems
• Small firms may charge too little and not make adequate margins. Many small establishments cannot deliver services charged by chain operators.
• Heterogeneity of services across and within providers also makes it difficult for a firm to follow this approach. (eg different banks have different charges for making D.D.s.
• Price signaling occurs in a market with a high concentration of sellers. Any price offered by one company will be matched by competitors to avoid giving a low- cost seller an advantage eg airlines.
• Going - rate pricing involves charging the most prevalent rate in the market. ( eg Taxi operators in NCR). For years the rates set by Hertz for car rentals were matched by all others.
Demand - based pricing
This involves setting prices in accordance with customer perceptions of value. Price is based on what the customer will pay for the services provided. In this approach non - monetary costs and benefits must be factored into the calculation of perceived value.
Problem
• When services require time, inconvenience, psychological and search costs, the monetary price must be adjusted to compensate.
• And when services save time, inconvenience psychological and search costs, the customer is willing to pay a higher monetary price.
• The challenge is to correctly assess the value to customers of each of the non- monetary aspects involved.
What colour would a red flag appear in red light?
A red flag would appear red in red light because the color of an object is determined by the light it reflects. In this case, the red flag would reflect red light, making it appear red.
How did the giant ground sloths die?
Giant ground sloths are believed to have gone extinct at the end of the Pleistocene epoch around 11,000 years ago. The exact cause of their extinction is still debated among scientists, but likely factors include climate change, human hunting, and loss of habitat. Evidence suggests that a combination of these factors contributed to their demise.
