Answer:
C
Explanation:
C. a system that converts thermal energy into other useful forms of energy
The answer is Carbon. Beyond being the only element listed here that is located in the second row, it is also in the fourteenth column of the table if you count from left to right. Hope this helps!
The frequency of rotation of Mars is 0.0000113 Hertz.
<u>Given the following data:</u>
- Period = 1 day and 37 minutes.
To find the frequency of rotation in Hertz:
First of all, we would convert the the value of period in days and minutes to seconds because the period of oscillation of a physical object is measured in seconds.
<u>Conversion:</u>
1 day = 24 hours
24 hours to minutes =
×
=
minutes
![1440 + 37 = 1477 \; minutes](https://tex.z-dn.net/?f=1440%20%2B%2037%20%3D%201477%20%5C%3B%20minutes)
1 minute = 60 seconds
1477 minute = X seconds
Cross-multiplying, we have:
× ![1477](https://tex.z-dn.net/?f=1477)
X = 88620 seconds
Now, we can find the frequency of rotation of Mars by using the formula:
![Frequency = \frac{1}{Period}\\\\Frequency = \frac{1}{88620}](https://tex.z-dn.net/?f=Frequency%20%3D%20%5Cfrac%7B1%7D%7BPeriod%7D%5C%5C%5C%5CFrequency%20%3D%20%5Cfrac%7B1%7D%7B88620%7D)
<em>Frequency </em><em>of rotation</em> = <em>0.0000113 Hertz</em>
Therefore, the frequency of rotation of Mars is 0.0000113 Hertz.

Answer:
The mass of the rule is 56.41 g
Explanation:
Given;
mass of the object suspended at zero mark, m₁ = 200 g
pivot of the uniform meter rule = 22 cm
Total length of meter rule = 100 cm
0 22cm 100cm
-------------------------Δ------------------------------------
↓ ↓
200g m₂
Apply principle of moment
(200 g)(22 cm - 0) = m₂(100 cm - 22 cm)
(200 g)(22 cm) = m₂(78 cm)
m₂ = (200 g)(22 cm) / (78 cm)
m₂ = 56.41 g
Therefore, the mass of the rule is 56.41 g
