Answer:
Number value and direction
Explanation:
Vectors are quantities that can be identified by value and direction . Examples are velocity and acceleration
The concept used to solve this problem is the conservation of momentum and the conservation of energy.
For conservation of the moment we have the definition:
Where,
m = Mass
= Initial velocity for object 1
= Final velocity
Replacing the values we have to,
By conservation of energy we know that the potential energy is equal to the kinetic energy then
Therefore after the collision the height when the combined chinks will go is 1.837m
Answer:
differences and similarities
Explanation:
An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound. whereas,
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
Answer:
it is the bottom one
Explanation:
the wavelength is shorter but more compressed.
Answer:
Explanation:
A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. ... In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
