7200 grams is what equivalen to 7.s kilograms
Answer:
As the liquid cools down, the amount of potential energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice
The "stuff" (molecules) in water is more tightly packed than in ice, so water has greater density than ice. Don't let the fact that ice is a solid fool you! As water freezes it expands. So, ice has more volume (it takes up more space, but has less density) than water

Answer:

Explanation:
Average acceleration is found by dividing the change in acceleration by the time.

The shuttle bus has an acceleration of -2.4 meters per square second. It slows from 9.0 meters per second to rest, or 0 meters per second. Therefore:

Substitute the values into the formula.

Solve the numerator.

We want to solve for t, the time. We have to isolate the variable. Let's cross multiply.



t is being multiplied by -2.4. The inverse of multiplication is division, so divide both sides by -2.4



It takes <u>3.75 seconds.</u>
These are digital signals.
