We know that arc length (x(t)) is given with the following formula:
Where r is the radius of the barrel. We must keep in mind that as barrel rolls its radius decreases because less and less tape is left on it.
If we say that the thickness of the tape is D then with every full circle our radius shrinks by d. We can write this down mathematically:
When we plug this back into the first equation we get:
We must solve this quadratic equation.
The final solution is:
It is rather complicated solution. If we asume that the tape has no thickness we get simply:
<u>Answer:</u> The correct statement is combining baking soda and vinegar will cause a chemical change.
<u>Explanation:</u>
A chemical reaction is defined as the reaction in which two or more chemical substances react to form two or more different chemical substances
A new substance (product) is formed in a chemical reaction when the bonds between the reactants are broken so that the new bonds between the products can be formed.
A physical process is defined as the process in which the physical state of matter takes place. Like, in the process of vaporization, a liquid state changes to the gaseous state without changing the composition of species.
When baking soda (Sodium bicarbonate) is reacted with vinegar (acetic acid), it leads to the formation of sodium acetate, water, and carbon dioxide.
A new compound is getting formed in this process which is denoted by the chemical equation:
Hence, the correct statement is combining baking soda and vinegar will cause a chemical change.
For every force, there is an equal and opposite reactionary force.
So when your weight acts on the bed, in order for the bed to not collapse, it must be able to exert an equal and opposite force back on you.
Answer:
Laws of the Park: Newton's First Law
If you understand how a skateboard starts and stops, then you already know something about Newton's first law of motion. This law was developed by English scientist Isaac Newton around 1700.
Explanation:
Hope this helps..
I reported this question by accident, I am sorry.
Anyways, there is no electric field at the center of a charged spherical conductor because all the charged particles are at the edges and because of the complete cancellation everywhere.
