Answer:
Part a)
Part b)
Explanation:
Let the length of the string is L
so here if the displacement from initial length is "x" then we have
now by energy conservation we have
now we also know that for 5 m length of the chord
so for L length of the chord we have
now from above equation
so by solving above we have
Part b)
Now when string is stretched by maximum amount then the acceleration will be maximum
so it is given as
<span>ΔE = 0
(m_alum) (c_alum) Δt - (m_water)(c_water) Δt' = 0
(30) (897) (20) - (20)(4186) Δt' = 0
Δt' = 6.42857 °C</span>
