Answer:
Final temperature = 
Explanation:
Given that,
Heat added, Q = 250 J
Mass, m = 30 g
Initial temperature, T₁ = 22°C
The Specific heat of Cu= 0.387 J/g °C
We know that, heat added due to the change in temperature is given by :
Put all the values,
So, the final temperature is equal to .
Answer: Radioactive waste
Explanation:
The nuclear fission reaction consists of heavy atomic particles or heavy nucleus, like plutonium and uranium and in radioactive heavy metals. In the fission reaction the nucleus get split into equal masses of particles. This process is associated with release of large amount of energy. The fission of radioactive waste can cause deadly mutations in living beings.

The speed of sound depends on these two things: The type of medium and the temperature of the medium; option a.
<h3>What is the speed of sound?</h3>
The speed of sound is the distance covered in meters over a given period of time.
Speed = distance/time
The speed of sound depends on the following:
- temperature - the speed of sound increases with temperature
- medium - the speed of sound increases with increase in density of the medium.
In conclusion, the speed of sound increases with temperature.
