In general, in the optics diagram,
* Ray 1 is a horizontal ray that after stopping by the optical system goes to the focal point
* Ray 2 is a ray that passes through the intercept point between the optical axis and the system and does not deviate
* Ray 3 is a ray that passes through the focal length and after passing the optical system, it comes out horizontally.

<h3>Answer :</h3>
Let the final temperature be "T".
For the piece of copper :
- mass,
- specific heat capacity,
- initial temperature,
Then the heat of copper :
For copper calorimeter :
- mass,
- specific heat capacity,
- initial temperature,
Then the heat of copper calorimeter :
For water :
- mass,
- specific heat capacity,
- initial temperature,
Then heat of water :
By energy conservation, the sum of all these energies should be zero as there were no heat energy change before the process, i.e.,

Answer:
Creatine reduces dehydration, muscle cramps or injuries.
Weight gain
Explanation:
Creatine supplements helps to increase amount of creatine in the body. Our bodies naturally have around 120 mmol/kg of creatine. By taking Creatine supplements this amount increases to around 140–150 mmol/kg. Creatine's main function is to help the muscles in your body to produce energy.
Some studies suggest that intake of Creatine reduces dehydration, muscle cramps or injuries. There have been numerous case studies which show that intake of Creatine causes weight gain. Numerous case studies have shown that increased level of Creatine in the blood stream does not affect the kidneys, liver and stomach.
