A large electroscope can be constructed using 78-cm-long wires for the leaves by attaching the wires to a metal rod or plate at the top, and then separating the wires at the bottom to form the leaves. The wires should be insulated and lightweight to allow for easy movement. This setup allows for the leaves to easily detect and respond to electric charges.
What else can I help you with?
What kind of charge the electroscope can detect?
The sphere of an electroscope is always neutral at first. Let's say a negative ebonite rod is brought close but not touching the sphere. (The entire electroscope is neutral). The electrons in the electroscope will want to repell the electrons in the rod so the electrons in the electroscope move down into the 2 leaves and then repell because there is a high concentration of negatives. When the ebonite rod is removed, the leaves go back to their straight position. The electroscope is always neutral but only a charge distibution occured. The number of protons and electrons remain the same. However if a charged rod touches the sphere then the electroscope will be charged because it a conductor and the charge from the rod transfers to the electroscope because the rod's caharges want to attarct to the electroscope's opposite charges. This is called charging by contact.
Predict what would happen if you touched the knob of a positively charged electroscope with another positively charged object?
In order to test the presence of a charge on an object, the object is brought near to an uncharged pith ball. If the object is charged, the ball will be attracted to it and move toward it. The attraction occurs because of induced polarisation of the atoms inside the pith ball. The pith is a nonconductor, so the electrons in the ball are bound to atoms of the pith and are not free to leave the atoms and move about in the ball, but they can move a little within the atoms. If, for example, a positively charged object is brought near the pith ball, the negative electrons in each atom will be attracted and move slightly toward the side of the atom nearer the object. The positively charged nuclei will be repelled and will move slightly away. Since the negative charges in the pith ball are now nearer the object than the positive charges, their attraction is greater than the repulsion of the positive charges, resulting in a net attractive force. This separation of charge is microscopic, but since there are so many atoms, the tiny forces add up to a large enough force to move a light pith ball. source: http://en.wikipedia.org/wiki/Electroscope
How are gravity dams constructed?
Gravity dams are constructed using large quantities of concrete to resist the force of water. The concrete is typically poured in layers, allowing each layer to cure before adding the next one. The weight of the dam pushes it down and anchors it to the ground, providing stability against the water pressure.
Why ball in the pith ball electroscope has to have a small mass?
The ball in a pith ball elecroscope is small because the ball must be able to move with little forces. If the ball had a large mass it would be difficult for a small force of attraction to occur.
What is a girrafes energy source?
Giraffes get their energy from the food they eat, primarily leaves and twigs from trees. They have a slow metabolism and spend most of their day eating to sustain their large bodies.
What is the Process by which large compounds are constructed?
Polymerization

Why do bushes have large leaves?
Most shrubs with large leaves grow in shade and need larger leaves to gather thelight required to do their job.

What is the indigestible waste called that leaves the large intestine?
The indigestible waste that leaves the large intestine is called feces.
Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)

false the two large groups are seed plants and nonseed plants
What do the large flat leaves do for a lily pad?
The leaves on a water lily give a large surface area for photosynthesis as much of the rest of the plant is underwater.
Can bay leaves kill you if consumed in large quantities?
Consuming bay leaves in large quantities is not recommended as they can be harmful and potentially toxic, but it is unlikely to be lethal.
