Answer:
A water fall?
Explanation:
It's an example I took in my science class
Answer:
Because it can desolve many many things.
Explanation:
Answer:
30 hours
15 hours.
Explanation:
Let the Kelly used sprinkler for t hours and Gracia used the sprinkler for the rest ie (45 - t) hours .
Water output by Kelly = (35 x t) L
Water output by Gracia = 20 ( 45 - t ) L
Total output = 35t + 20(45 - t)
So, 35 t + 20 (45 - t ) = 1350
35 t + 900 - 20 t = 1350
15 t = 450
t = 30 hours
So Kelly used sprinkler for 30 hours and Gracia used it for 45 - 30 = 15 hours.
Answer:
0.53 quart
Explanation:
The volume expansion of the coolant is gotten from ΔV = VγΔθ where ΔV = change in volume of the coolant, V = initial volume of coolant = 15 quart, γ = coefficient of volume expansion of coolant = 410 × 10⁻⁶ /°C and Δθ = temperature change = θ₂ - θ₁ where θ₁ = initial temperature of coolant = 6 °C and θ₂ = final temperature of coolant = 92 °C. So, Δθ = θ₂ - θ₁ = 92 °C - 6 °C = 86 °C
Since, ΔV = VγΔθ
substituting the values of the variables into the equation, we have
ΔV = VγΔθ
ΔV = 15 × 410 × 10⁻⁶ /°C × 86 °C
ΔV = 528900 × 10⁻⁶ quart
ΔV = 0.528900 quart
ΔV ≅ 0.53 quart
Since the change in volume of the coolant equals the spill over volume, thus the overflow from the radiator will spill into the reservoir when the coolant reaches its operating temperature of 92 °C is 0.53 quart.
The Answer is:
