Energy added = mass*specific heat* rise in temperature.
= 5 * (60-50) * 4.18
= 50*4.18
= 209 J (answer).
The spring constant determines how far the spring will stretch for a given applied force: <span>F=kx→k=<span>Fx</span></span><span>. If we place the same mass on the two springs, which means we have placed the same force on them, the one that stretches </span>least<span> has the largest spring constant.
Hope this helps!

Answer:
Explanation:
- The formulae used in solving the problem ; ΔTf = i × Kf × m
- where ΔTf = depression in freezing point ,
- i = vant hoff factor 1 for non dissociable solutes ,
- Kf = freezing point constant for solvent
Appropriate substitution was done as shown in the attached file.
