Because angular momentum is conserved, an ice-skater who throws her arms out will

This is an example of conservation of angular momentum.

The ice skater will rotate more slowly because her arms would be considered the outside torque that is impacting her constant angular momentum.

So, an ice-skater who throws her arms out will rotate more slowly.

Please help me<br> the formula is E = P x t
Rainbow [258]

The battery doesn't 'use' power.  The battery <em>produces</em> the power that all the other electrical devices use.

If the starter motor is using 2,520 watts, then the battery is producing energy at the rate of 2,520 watts.  That means <em>2,520 Joules</em> of energy every second.

Thanks for giving us the formula.

E = P x t

Energy = Power x Time

Energy = (2,520 watts) x (1 second)

Energy = 2,520 Joules

Write a short story that describes haw matter changes from one physical state to another
marin [14]

I'll assume this is can or is fictional prose.


Two Icecubes sat in a freezer in the kitchen. One was so bold to claim he could survive walking across the stove. As he made his way to the stove, he noticed he was leaving a wet trail, "no matter" he thought and continued his path. He touched the stove and in an instant was no longer an ice cube. He was a puddle, but not for long. He then started to float and became steam.


Thus he went from solid to liquid to gas.
