The electrical current in a wire could be from multiple things. This is how we wire our house. When the electrical current flows through the wire, it can power things like lights and appliances. The things that flow through a wire are called electrons.
Answer:
Explanation:
Every chemical reaction can be represented by simple chemical equations that shows how compounds are combining to give some products.
Such reactions are usually made up of:
Reactants on the left hand side
Products on the right hand side
Reactants → Products
In this given problem;
Reactants are : Magnesium fluoride = MgF₂
Iodine in form of Iodide = I₂
Product : Magnesium iodide = MgI₂
MgF₂ + I₂ → MgI₂ + F₂
Answer:
C
Explanation:
this is because i need more space
Mv + mv = 2mv providing each momentum is in the same direction.
1/2 mv^2 + 1/2 mv^2 = mv^2
Potential energy + kinetic energy = constant at every moment in time
At the highest point:
potential energy is at its maximum
kinetic energy is zero
