Answer:
Gravity Increases - Mass increases, distance decreases
Gravity Decreaes - Mass decreases, distance increases
I think the best would be B my friend
A.
Because you increase the concentration of the reactants, it means that there are more molecules of the reactants present in a smaller amount of space.
This being the case, there is a higher chance that these molecules will collide with enough energy to overcome the activation barrier.
The other ones are completely wrong, but if you would like an explanation as to why they are, just ask :)
Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Answer: correct option is C
both Technicians A and B are right
Explanation:
Test cycles specify the specific conditions under which the engine or vehicle is operated during the emission test. The vent valve that is not able to close can cause the system to fail the on-board test. Also, a leaking gas cap can cause a failure of the EVAP test.
There are many different test cycles issued by various national and international governments and working groups
