Why does a solid needle placed horizontally on the surface of the water float?
Due to surface tension
When find out all force is zero?
If a glass marble is placed on a level surface, the only forces are gravity (which prevents the marble from floating off the surface), and the lack of lateral force (it is not pushed by hand), and friction as the surface is level. One could assume, that only in a vacuum jar, would the marble have zero force. But then, surely, the earth gravity must still have some effect?
The pebbles lying at the bottom of the clear water of the river appears to be raised up above their actual positionwhy?
Because when light enters a denser medium it is refracted towards normal. The same effect is seen when a straight stick is placed at an angle half into water. The stick appears bent at the point it enters the water. This phenomenon is called 'real and apparent depth', if you are interested.
Why does a drop of oil placed on the surface of water spread over the entire surface?
because the water has more density than the oil so the oil spreads only on the surface.

What is one effect of water's stickiness or cohenion?
One effect of water's stickiness or cohesion is its ability to create surface tension. This allows water molecules to stick together and form droplets or maintain the shape of objects placed on its surface, such as insects walking on water.
Where is a seismograph placed?
A seismograph is placed under the ground. Somewhere not to close to the surface, as when something on the surface moves, then it would be recorded on the seismograph. Something on the surface that moves can be a vehical driving along the road.

Part of a pencil that is placed in a glass of water appears bent in relation to the part of the pencil that extends out of the water What is this phenomenon called?
Caused by refraction. The same effect causes a depth of water to be smaller than it really is.
Contact lenses are placed on what surface of the eye?

How do you catch aron in Pokemon soulsilver version game?
Aron is found in the Safari Zone. You must figure out which zone he appears in, as there are many to choose from. You must also decide which items and how many need to be placed, as that will have an effect, as well.
Hall effect in electronics and communication?
When a current carrying conductor placed in magnetic field than a voltage across the surface is arise this voltage is known as hall voltage and this phenomenon is know as hall effect. It is useful for consider whether the applied material is PNP or NPN
What element on the periodic table appears to the left of copper?
Nickel is placed on the left of copper.
Why are freezers placed on top of refrigerators?
because refrigerators are placed on surface of buildings so heat may passes higher
Will different weights effect the speed?
