Answer:
42°C is equivalent to 315.15 K.
Explanation:
In this question, we need to convert the temperature from one scale to another. A glass of cold water has a temperature of 42 °C. The conversion from degree Celsius to kelvin is given by :
Where
are temperatures in degree Celsius and kelvin respectively.
So,
So, 42°C is equivalent to 315.15 K. Hence, this is the required solution.
Answer:
7.69 hours
Explanation:
3 hr/ 1000mi x 130mi = 7.69 hours or 7.7 hours
<span>The gain in potential energy is 600*2 = 1200 J, and this is the minimum required work that would be required in a frictionless situation. The work that actually has to be done is F*X = 300*5 = 1500 J. The efficiency is therefore 1200/1500 = 80%</span>
