Convert the temperature scales:
-> TC (Celsius Temperature)
-> TF (Fahrenheit Temperature)
->TC/5 = TF - 32/9
-30/5 = TF - 32/9
-270 = 5TF - 160
5TF = -270 + 160
5TF = -110
TF = -110/5
TF = -22 Fahrenheit
- 30 °C = -22 °F
So, -30°C is warmer than -30°F.
-30°F is lower than (30°C) -22°F.
"The number of waves per second will increase" is the statement among the choices given in the question that <span>will be true if you increase the frequency of a periodic wave. The correct option among all the options that are given in the question is the first option or option "A". I hope that the answer has helped you.</span>
Answer:
Time period of the osculation will be 0.0671 sec
Explanation:
It is given a vertical spring is stretched by 4 cm
So change in length of the spring x = 4 cm = 0.04 m
Mass which is hung from it m = 12 gram = 0.012 kg
Sprig force will be equal to weight of the mass
So 
k = 244.7 N/m
Now new mass is m = 28 gram = 0.028 kg
So time period with new mass will be
<h2>Answer:</h2>
The correct answer is option D. Which is "Over time, the lawn has naturally become disorderly".
<h3>Explanation:</h3>
- Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
- It is also a measure of the molecular disorder, or randomness, of a system.
- According to above definitions of entropy option D is correct.
- <u>So entropy of system is randomness/disorder that is increasing with time in case of lawn.</u>
