They have 6 valance electrons.
Answer:
newton's 3 laws state:
- an object in motion stays in motion (unless an external force acts on it)
- every action has an opposite but equal reaction
- force= mass x acceleration
Answer:
B, C, and D
Explanation:
A is the only one in which two components are being combined. The point is to separate the mixture, so that is the only one that would not apply.
The options are;
A) The skater experiences acceleration both while skating in a straight line and while making her turn.
B) Because the skater does not change her direction or speed, she does not experience acceleration.
C) The skater only experiences acceleration when she is turning.
D) The skater only experiences acceleration while skating in a straight line.
Answer:
A: The skater experiences acceleration both while skating in a straight line and while making her turn
Explanation:
We are told that She speeds up on the straight portion of the rink. This means that she experienced an acceleration since the speed was not constant but gradually increasing.
Also, we are told that She slows down near each end of the rink and then turns around. This means that she reduced speed before turning and it means there was also an acceleration as well when making the turn.
Thus, she experience acceleration both in the straight line and when making turn.
Option A is correct
