Answer:
September 9 and 24 represent spring tides due to the added gravitational pull of the Sun.
Explanation:
Just trust me
The final temperature of the mixture is closest to 32.5 °C
<h3>Data obtained from the question</h3>
- Mass of warm water (Mᵥᵥ) = 50 g
- Temperature warm water (Tᵥᵥ) = 40 °C
- Mass of cold water (M꜀) = 30 g
- Temperature of cold water (T꜀) = 20 °C
- Specific heat capacity of the water = 4.184 J/gºC
- Equilibrium temperature (Tₑ) =?
<h3>How to determine the equilibrium temperature </h3>
Heat loss = Heat gain
MᵥᵥC(Tᵥᵥ – Tₑ) = M꜀C(Tₑ – M꜀)
50 × 4.184 (40 – Tₑ) = 30 × 4.184(Tₑ – 20)
209.2(40 – Tₑ) = 125.52(Tₑ – 20)
Clear bracket
8368 – 209.2Tₑ = 125.52Tₑ – 2510.4
Collect like terms
8368 + 2510.4 = 125.52Tₑ + 209.2Tₑ
10878.4 = 334.72Tₑ
Divide both side by 334.72
Tₑ = 10878.4 / 334.72
Tₑ = 32.5 °C
