Answer:
The entropy of the gas increases
Explanation:
The entropy of an isolated system tends to increase. but this gas gas is not isolated. It has a piston perfoming work on it and it can exchange heat with it's surroundings.
While the system's entropy decreases, the surroundings' entropy increases, and the entropy change of the universe, which is the sum of the entropy changes of the system and the surroundings, will be equal or greater than zero.
Answer:
Trial and error.
Explanation:
This approach of Thomas Edison where in testing of thousand of different material for light bulb filament are used to find the most suitable material is called trial and error approach of problem solving.
Trial and error pursue a method, seeing if it performs, and not trying a new mechanism. This mechanism will be repeated until a solution or success is attained. Assume moving a large object like a couch into your house for example.
E = 1/2 kx^2
Make k the subject of formula.
Find the base units of E and x.
Replace back in the equation and find the base units of k.

Hope it helped!
there are different types of power so ill show you all the examples of power.
This drag force is always opposite to the object's motion, and unlike friction between solid surfaces, the drag force increases as the object moves faster.
