B. Purchase a small plastic container and mark 1-ounce increments on the outside to determine volume. Pour 5 ounces of water into the container, and place in the freezer for 8 hours. Compare the frozen or ending volume with the liquid or beginning volume.
<h3>How much water expands when frozen?</h3>
Ice is less denser than the liquid form. Water is the only known non-metallic substance that expands when it freezes because it is the unique property of water. Water density decreases and it expands approximately about 9% by volume. For calculating the expansion of water, plastic container is the best option. We know that water expands when the water freezes because it is a unique property of water which allows the survival of aquatic organisms.
So we can conclude that option B is the right answer.

Answer:
Check the attached image below.
Explanation:
Kindly check the attached image below to get the step by step explanation to the above question.
Answer:
R = 545.38 m ; θ = 28.43°
Explanation:
given,
for town A : d₁ = 335 km at an direction of 20° north of east
for town B : d₂ = 245 km at 30.0° west of north from town A
x = 335 cos 20° + 245 sin 30°
x = 437.29 m
y = 335 sin 20° + 245 cos 30°
y = 326.75 m
R = 545.38 m
θ = 28.43°
The slope of the distance/time graph is the speed of the moving object.
So the graph for a fast moving object will have a greater slope than the
graph for a slower moving object has.
<span>Well, the main point you should remember is that we only can hear 20hz that leads to T=0.05sec
which means that the distance leads us to velocity x time.
When calculating, you get 330 * 0.05=16.5 .
The number which you got from the previous step has to me multiplied 4 times (4 minutes) and you will get the answer you need - </span><span>a) 66.0 m.
Do hope it will help you! Regards!</span>
