Answer:
C. a clamp light with a 150-W lightbulb placed 25 cm from the radiometer
Explanation:
because the temperature has to be set, meaning it can't change, and it should be a different distance away than the first one.
Hope this helps! Stay safe!

Answer:
The elastic potential energy of the spring change during this process is 21.6 J.    
Explanation:
Given that,
Spring constant of the spring, 
It extends 6 cm away from its equilibrium position.
We need to find the elastic potential energy of the spring change during this process. The elastic potential energy of the spring is given by the formula as follows :

So, the elastic potential energy of the spring change during this process is 21.6 J.
