Hey
in the summer it is because of the meting of snow
in the spring it is rain
hope l helped
Because it is not a good conductor of heat. so the answer is D.
The best and most correct answer among the choices provided by your question is the fourth choice or letter D.

We can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.
<h3>How we can calculate the thickness using screw gauge?</h3>
We can determine the width/thickness of a coin by using a screw gauge because screw gauge is an instrument that measures thickness of an object that are very thin. First we can placed the coin in between the teeth of the gauge and then move the gauge until the coin can be held tightly. After that note the reading on the scale.
So we can conclude that we can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.

Answer:
0.0473m
Explanation:
345 ml = 0.000354 m3
6.5 cm = 0.065 m
20g = 0.02 kg
Since can is half filled with water, the water volume is 0.000354 / 2 = 0.000177 m cubed
Let water density be 1000kg/m3, the mass of this half-filled water is
1000*0.000177 = 0.177 kg
The total water-can system mass is 0.177 + 0.02 = 0.197 kg
For the system to stay balanced, this mass would be equal to the mass of the water displaced by the can submerged
The volume of water displaced, or submerged can is
0.197 / 1000 = 0.000197 m cubed
Then the volume of the can that is not submerged, aka above water level is
0.000354 - 0.000197 = 0.000157 m cubed
The base area of the can is
The length of the can that is above water is
0.000157 / 0.003318 = 0.0473 m
