Explanation:
Given that,
Efficiency of heat engine,
Temperature of hot source,
We need to find the temperature of cold sink i.e. . The efficiency of heat engine is given by :
So, the temperature of the cold sink is 256.2°C. Hence, this is the required solution.
<h2><u>Answer:</u></h2>
<u></u>
<u>Force = kgm/s² ⟶ Newton</u>
<h2><u>Explanation:</u></h2><u></u>
According to the formula we've learnt,
- Force = mass × acceleration.
To find force in terms of base units, we must first identify the base SI units of mass & acceleration.
- Base SI unit of mass = kg (kilogram)
- Base SI unit of acceleration = m/s² (meter per second squared)
So, the base unit of force is,
- Force = mass × acceleration.
- Force = kg × m/s²
- <u>Force = kgm/s² ⟶ Newton</u>
