Red is commonly known for violence representation. So, the bull charges towards the object violently
Bats use an echolocation to find out where an object is for food. Bats use a certain method like a high pitch sound that is sent out and is reflected of of the object and is sent back to the bat so it knows where to go. Sometimes insects use high pitch sounds that the bat hears an it goes towards the sound.

This is known as electrostatic induction. As charged object (say positive) is brought near by the neutral object the opposite charges i.e. negative would get attracted towards and positive charges would be pushed away. Yet the object is neutral though the charges got separated. Now due to attraction of unlike charges the neutral is attracted towards the charged one.
Clear.
When the charges of one object separate to opposite sides of the object, the object is polarized. It is polarization.
Static charge is the buildup of electric charges on an object. This is a Biology question.
Electrons move onto the object, giving it a static charge. Apex ;)
They separate, with positive charges on one side and negative charges on the other.
You see different coloured objects by light. the light hits the object and reflects into your eyes.
A object without electrical charges.

transfer of charges from one object to other
A neutral pith ball is still "charged", it just doesn't display excessively charged behavior. Since it is neutral, having nearly equal positive and negative charge, the proximity of the positively charged pith ball still attracts the negative charge present in the ball, inducing polarization moving the ball closer to the positively charged one. Once they make contact, the conductibility of the pith ball quickly accepts excess charge from the other, creating a like charge repulsion.
Most of the time, in an object, its negative and positive charges are balanced, which makes it a neutrally-charged object. Sometimes, when some objects come into contact with other things, they gather more charges of one type. If there are more electrons, they are negatively-charged. If there are more protons, they are positively-charged. Because opposites attract, an object which is negatively-charged will attract another object which is positively-charged and vice versa.
