<h2>Hello!</h2>
The answer is: A. 4.5 L
<h2>Why?</h2>According to the conversion factor which states that:
It means that we have 3.78 L per each gallon or it's equal to say that we 0.26 gallon per each L.The SI unit for liquid volume is the Liter (L)
Let's make the calculations:
So, we have 4.54 L in 1,2 gallons.
Have a nice day!
Answer:
The volume of water is 139 mL.
Explanation:
Due to the Law of conservation of energy, the heat lost by coffee is equal to the heat gained by the water, that is, the sum of heats is equal to zero.
The heat (Q) can be calculated using the following expression:
where,
c is the specific heat of each substance
m is the mass of each substance
ΔT is the difference in temperature for each substance
The mass of coffee is:
Then,
The volume of water is:
This Question has mistakes.Correct question is
An undamped oscillator has period τo=1.000s , but I now add a little damping so that its period changes to τ1=1.001s.
What is the damping factor β? By what factor will the amplitude of oscillation decrease after 10 cycles? Which effect of damping would be more noticeable, the change of period or the decrease of the amplitude?
Answer:
β=0.28 /sec
Amplitude=0.0606
