Get the value of initial velocity. Get the angle of projection. Break initial velocity into components along x and y axis. Apply the equation of motion .

So it becomes a fair test and you can make sure you didn't make any mistakes :)

The ideal situation is when the sun is behind you and rain is falling in the distance ahead of you. As the sunlight reflects off the raindrops, it is separated into all of its colors.

haha i have the same hwork book and am stuck on the same thing... someone please "improve" my answer so we can finish this...

The mother sow provides all the nutrients needed by the fetus until birth. Directly into the blood stream.

If you mix chemicals together and want to write down your results, then you have to wait a bit for the formula to mix. If you take the result right away, you won't get an accurate result because the chemicals have not combined w/ each other yet and it takes a while until they do. Then you'll outcome will be correct if you wait a while.

An egg can bounce after soaking in white vinegar for around 24-48 hours. The vinegar dissolves the calcium carbonate in the eggshell, making it rubbery and bouncy. Experiment with different timings to find the desired bounce level.

When boiling ethanol, the gas inside the bubbles is mainly ethanol vapor along with some air. Ethanol vapor is formed as the liquid ethanol heats up and turns into a gas, creating bubbles that rise to the surface.

Definatly not! A Neutron is a kind of Baryon (a type of Hadron) made up of the subatomic particles: Up quark, Down quark and Electrons. Now a Neutrino is different, there are three different types. There are Electron Neutrinoes, Muon Neutrinoes, and Tau Neutrinoes. Neutrinos are a type of Lepton, for every Neutrino there is a equivalent non-neutrino. For example, There is an Electron and an Electron Neutrino. So to conclude Neutrino does not mean Neutron, instead it is describing a type of Lepton. This should answer the Question.

The boiling point of water at sea level is 100 degrees Celsius (212 degrees Fahrenheit). When heated on a gas stove, the water will reach its boiling point and start to boil, forming bubbles and producing steam.

The longer the air column in an instrument, the lower the pitch it will produce. This is because longer columns of air vibrate at lower frequencies, creating deeper tones. Shorter columns of air vibrate at higher frequencies, resulting in higher pitches.

salivation to the food

yes. AKA the independent variable

Plants grow well in soil that is rich in nutrients, well-draining, and has good aeration. They also thrive in areas with adequate sunlight and water. The specific needs of plants can vary, so it's important to research and understand the requirements of the plants you are growing.

Aim-To stained tempory mount of onion peel to record observation and draw labelled diagram

Materials requires :- onion peel plane cover slip ;watch for caps ,needle, brush, saframinesolution, filterpaper ,glycrine&microscope.

Procedure:- (1) take out a piece of transparent onion peel with the needle are for caps.

(2) dip this onion peel in saframine solution kept in watch glass.

(3)take a small piece of stained onion peel &put on slide.

(4)clean the pel with the help of needle & brush

(5)part a drop of glycrine over stained pul the cover slip gentel over it shoked extream material by clothing paper.

(6)examine the slide under microscope.

Observation:-the slide show a large number of rectangular &square shape cells.

result :-onion peel consist of rectangular cell.

precaution:-(1)over and under staining shoud be avoid.

(2):-extra material should shoked by paper.

(3):- small & thin peel should be taken.

sedimentary rocks are formed

control

Yes. Bees are an amazing study. Think of what life would be with the bee?

Mostly because of blood flow ...

a dead (human) body does conduct heat (because its mostly water), but quite slowly.

The average IQ for any and all age groups is 100. all tests are specically designed for the age group they are testing ie. a 14 year old will take a test for 14 year olds and a 5 year old will take a test for 5 year olds.

These are experiments where an egg is sucked into a bottle, when

-- the bottle is heated, then allowed to cool

-- a burning piece of paper is placed inside

These have been used to demonstrate the effects of

-- temperature and pressure

-- the chemical binding of oxygen by oxidation

...and have been around since the 19th century (anytime since the invention of the glass milk bottle around 1877).
