Answer:
The potential energy of both toy vehicles (purple and pink) decreased. Since the pink toy was moved closer to the magnet, it will have less potential energy because of the short distance it will take to travel to the magnet. Although the purple toy is now closer to the magnet, it is still pretty far and will have a somewhat big potential energy when traveling to the magnet.
Explanation:
Hey, I'm in middle school and I had the same question for a science test, I'm not sure if I am correct but this is what I have.
Answer:
Yes
Explanation:
Yes heating water allows it to dissolve more Sugars because the molecular distance increases and this distance can be covered by more sugar. In the given question, The independent variable would be the temperature of water.
Since to whatever temperature the water boils at the boiling temperature of does not change remains hundred degree. Rest all the variables can vary the weight of the amount of sugar with the variable in the temperature of Boiling of water to remain constant.
Answer:
The volume of the marble is 10 mL.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 10 mL
Rise in water = 10 mL
Volume of marble =.?
From the question given above, the water level rise by 10 mL when a glass marble was placed into the water.
This is equally the volume of the marble as the marble will displace it's volume when placed in the water according to Archimedes' principle.
Therefore,
Rise in water = 10 mL = volume of marble.
Answer:
1.8g/cm³
Explanation:
Density is defined as the ratio of the mass of a substance and the space this subtance occupies. It is usually given in g/cm³.
The mass of the block is 30g.
The volume this mass occupies is 1.5cm × 4.8cm × 2.3cm = 16.56cm³.
The density is:
30g / 16.56cm³ =
<h3>1.8g/cm³</h3>
