After, and at the exact moment, the ball leaves the hand it is only accelerated by gravity if you disregard air resistance.
Witch battery last longer energizer or Panasonic?
Panasonic lasts the longest.. it worked really long. it lasted 5 hours and the energizer battery only lasted 3 hours.. we did an experiment checking which battery lasted the longest by taking pictures on a camera until the battery died.
Does music affect students answering math questions?
Yes, because sometimes it can be very distracting to the students. Especially if they are trying to concentrate.
Is the egg drop project a 8Th grade science project?
yes, this is usallualy done by eighth graders who build a box out of different materials and drop them from their school bleachers, then they unwrap their boxes to see if their egg survived.
Is a nickel less dense than a dime?
Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.
yes, because a doorstop wedges the door. So it would be a wedge.
How do people use hydroelectric energy?
people use hydroelectric energy to power almost anything from cars to ur hair dryier . But it is mostly used to power houses. basically people use it for electricity
Does softened water or bottled water effect plant growth?
It depends on the plant and on the klimate the plant originate from Some orkids can only survive with softened water, others cant survive without alot of calcium in the water(tap-water)
- and in a less extreme variant it is the same with all other plants Most rainforest-plants like demineralised water(tumbledryer-water) bottled water is no better than tumbledryer-water so use the cheaper. Tap water is totally fine, but if you have múch bacteria in your tapwater it may be a problem for some plants but not for others.
Variables used in an experiment or modelling can be divided into three types: "dependent variable", "independent variable", or other.
The "dependent variable" represents the output or effect, or is tested to see if it is the effect.
The "independent variables" represent the inputs or causes, or are tested to see if they are the cause. Other variables may also be observed for various reasons.
when a country is completely or almost completely dependent on importing in necessary consumer items
What is the difference between a procedure and a experiment?
A procedure is all the steps used to do an expirament in order.
the expirament is when you test your hypothesis and is designed to answer your question.
the procedure is all the steps of the expirament.
How many decimeters are in 26.1 meters?
There are 10 decimetres in one metre. Therefore, 26.1 metres is equal to 26.1 x 10 = 261 decimetres.
Why is it important to be objective while conducting research?
Because subjectivity leads to partisanship, which contradicts the very idea of research, id est the search for the truth.
Different types of clothing and a backpack. A backpack must be controlled in this experiment. Hope this helps students. ( Science Teacher ) :)
What provides the centripetal force for a car driving on a circular track?
The road, pushing against the tyres.
Professor Oliver Headley was a scientist from Barbados who promoted alternative energy.
No. The only people ever recorded to have done this without flotation aids are Jesus Christ and his disciples, when Christ was rescuing the others from a sinking boat (whether one believes this was a miracle, or that Christ was actually walking on a submerged sandbank, is open to debate). But other than this example, no. A French inventor in the late 19th Century perfected 'foot canoes', which were like a pair of miniature kayaks that were worn one on each foot and enabled the wearer to skate along on water rather like wearing roller-skates. These never caught on, I think because they were considered too dangerous if you overturned. Some acrobats and stunt-performers are able to 'jump' across short stretches of water whilst holding a heavy weight in each hand, using the same principles of motional dynamics as apply when you skim a stone across a pond.

How are solar panels good for the environment?
If you've happened upon this article because you are looking for information on how solar panels help the environment, get set to find yourself amazed. You are going to discover the easiest way how to equip your house with a limitless source of free energy, and get paid for your efforts! Sounds unrealistic? Indulge me a little bit - continue on with this brief article.
What's the point of spending your hard-earned money on electricity when you can have your own solar-based power source system, equipment that you can create and install yourself - now that's easy! And fortunately, this system doesn't cost much; solar was most common on luxury homes up until recently, but now it's become the economical way to go.
How did i learn all this? I had heard about some of the benefits of solar energy, and was doing some research on how solar panels help the environment and i learned that while it was fairly new to me, there were many who had already "seen the light" and have been enjoying the rewards of a system which turns ordinary sunlight into an abundant supply of electricity in no time. A quick research on that reveals another amazing fact - all this is obtainable with the purchase of a few everyday materials, at a cost that anyone and I'll say it again: anyone can afford. Former restrictions like accessibility and cost have been removed and we can benefit from technology which gives us the ability to benefit from a free source of electricity for as long as we live.
What does data mean in science?
Data are either the results of experiment express in the measure form of numbers, or those numbers under some conditions of statistical analysis.
