Stop, in the Name of the Law!
What opposite charges do
What is attract each other?
What type of wave is a sound wave?
Longitudinal
Which one is stronger electrical force or gravitational force?
Electrical Force
According to Coulomb's Law, given 2 charges, if one charge triples in magnitude, the force will do this.
What is triple?
What type of wave is a light wave?
Transverse wave
In Coulombs law equation, k represents the electrical proportion constant. What is the number for k
9,000,000,000 M* m2/C2
According to Coulomb's Law, given 2 oppositely charged objects, if the positive charge exerts 10 N of force the opposite charge will exert this much force.
What is 10 N?
When we charge an object by touching it.
What is charging by contact?
What are the parts of the electromagnetic spectrum?
Radio, Micro, infrared, Light Ultraviolet, xray, Gamma
Force is measure in what unit?
Newtons
According to Coulomb's Law, given 2 fixed charges, if the distance is doubled the force will do this.
What is decrease 4 times?
The charge of an atom that gains electrons.
What is negative?
How do you measure the speed of a wave?
Veloctiy= Wavelength X Frequency
What is it called with an atom loses or gains an electron?
an Ion (Positive ion or Negative ion)
This is Coulomb's Law
What is F = k(q1)(q2)/d^2
The reason why most matter is neutral.
What is an equal number of protons and electrons?
This way of charging causes the the object to have the same charge as the object used to charge it
Conduction- charging by contact
What is the conservation of charge?
A charge can not be created or destroyed it is transferred.
What is the formula for Photosynthesis?
Water + Carbon dioxide----->Oxygen + Sugar
