Answer:
The impulse experienced by the object equals the change in momentum of the object. In equation form, F.t = m. Δv. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.
Answer: Mohs Scale
Explanation: Mohs Scale of Hardness
hope this helped!!!!!!!!!!!
AC reverses the current in periods, and the current flows in 2 directions.
DC only flows in one direction and is constant.
AC is typically used to transfer power over long distances from a generator to your home, stepping it up after it's generated to send it over the distance, then stepping it back down so that it is usable in your home.
DC is used typically inside of devices, as it sends a certain amount of electricity through the wires.
Nicolas Tesla, was ripped off by Edison to replace his DC stations with AC instead. ^^
Thermal-energy flow between objects is conserved and always flows from the warmer object to the cooler object.
Here 'conserved' means that the amount of thermal energy lost of by one body is exactly equal to the amount of thermal energy gained by another body, which is the statement of the first law.
According to second law, we do not see objects warming up on their own. For example, if we have a cup of coffee left to itself, we would always see that it cools down. Here, thermal energy is being transferred from warmer object (coffee) to cooler objects (the air in the room).
Answer:
Single Compound
Explanation:
A synthesis reaction takes two or more reactants and reacts chemically to turn them all into one substance.
An example of a synthesis reaction is the reaction that takes place between sodium (Na) and chlorine (Cl) to create table salt.
