5.6 g/ml. That is the density.
Answer: The first answer for the first problem, and the 2nd answer for the second problem
Explanation: For the first one, if it is absolute zero, the molecules would not move at all.
For the second one, the temperature of the sample will increase due to the movement.
Answer:
Explanation:
We know that the volume V for a sphere of radius r is
If we got an uncertainty 
the formula for the uncertainty of V is:
We can calculate this uncertainty, first we obtain the derivative:
And using it in the formula:
The relative uncertainty is:
Using the values for the problem:
This is, a percent uncertainty of 4.77 %
Answer:
For Yanni, the speed of the ball is 15 m/s, and for the quarterback, the speed of the ball is 8 m/s.
Explanation:
B. Helium because it is constantly being made in the sun
Explanation:
From the given paragraph, we can conclude that helium is the most common element in a star such as the sun because it is constantly being made.
In the nuclear fusion process that results in the production of helium, hydrogen nuclei are the reactants and helium is the product.
- since the reactants are constantly being used in the core of the sun, this suggests that the products must be more.
- The reaction requires a high temperature and pressure to initiate.
- It is a series of chain reaction that uses a fuel of hydrogen to produce helium.
