Answer:
Spin a coil of wire inside a magnetic field or move a magnet inside a coil of wire.
Explanation:
This is according to Faraday's law of electromagnetic induction.
Answer:
Increases.
Explanation:
The electric potential increases when the two positive charges of same magnitude bring close to one charge to another because there is repulsive force between them due to same charge and when the two opposite charges move away from each other, the potential energy decreases. When two opposite charges are brought closer together, electric potential energy decreases while on the other hand, when we move opposite charges apart from each other than the work done against the attractive force that leads to an increase in electric potential energy.
I learnt this in chemistry but... relative abundance tells us the percentage of how much that certain isotope occurs in nature.
It has both potential and kinetic energy.
Since the ball is falling through the air its going to keep going faster and faster since gravity is pulling it downward so its not going to stop unless it hits something or someone catches it.
Answer:
125 Joules
Explanation:
In an elastic motion, the net kinetic energy of the system is conserved i.e the total kinetic energy of the system after the collision is equal to the total kinetic energy of the system before collision;
Kinetic Energy = 1/2 m*v^2
Total Kinetic energy = Kinetic Energy(Cart 1) + Kinetic energy(Cart 2);
Total K.E = 0.5*(10)*(5)^2 + 0 = 125 Joules;
Energy after collision = Energy before collision = 125 joules
