The second law of thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative.
Answer:
1.00 m/s^2
Explanation:
The problem can be solved by using Newton's second law:
where
F is the net force acting on an object
m is the mass of the object
a is its acceleration
In this problem, F=35 N (the force applied by Amber) and
is the mass of the wagon + the brother, so the acceleration of the wagon and the brother is
<h2>Answer: 10,000 times
</h2>
Thomas Alva Edison was a North American scientist and inventor who is credited with the design of the electric bulb and many other patented inventions.
However, the bulb did not come out on the first attempt, and was sometimes questioned by his repeated "failures". But his patience and perseverance paid off, after approximately 10,000 attempts, he managed to obtain an incandescent bulb that would last for a long time.
It should be noted that Edison was once asked if he considered that he had had many failures before making the bulb work, hence his famous phrase:
<h2><em>“I have not failed 10,000 times—I’ve successfully found 10,000 ways that will not work.”
</em></h2>
That is why Edison is considered an example of perseverance.
Friction is a force. A resistance force that tries to slow down and stop objects in motion. The difference between friction and air resistance is that friction acts on surfaces. For example, if I were skateboarding on a rough surface, more friction would occur so I would travel slower. If I were skareboarding on ice, I would go faster because there is much less friction to slow me down. Hope that helps:)
