Ascientist is studying the different rates at which different parts of a car rust in a humid garage. describe the system the scientist is studying

Answer :  the system the scientist is studying consists of the car, the humid garage and Air

Explanation:

In order to find the system, the scientist is studying, we need to take a look at what happens to different parts of a car in a humid garage.

Majority parts of the car are made of iron. In humid garage, there is moisture ( Water vapors)  in the air. When iron comes in contact with oxygen from air and moisture, corrosion of iron begins. Corrosion is a reaction of iron with oxygen in presence of water which produces iron oxide which is known as rust.

Therefore we can write down the equation for the reaction that is occurring in a humid garage

Iron ( Parts of car) + Water ( humid garage) + Air ( oxygen) ⇒ Iron oxide ( Rust)

Therefore the system the scientist is studying consists of the car, the humid garage and Air

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
