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.
The properties of acids are: (A), (C) and (D).
Explanation:
Acids taste sour, and most
acids are poisonous. Furthermore, acids react with certain metals to
produce hydrogen gas. Few acids are corrosive as well. The option (B) is not valid because acids react with BASES (not with other acids) to produce salt and water. Hence A, C and D are the correct options.
Answer:
Explanation:
In this case, since the charged particle moves in circular motion, the centripetal force is equivalent to the magnetic force.
