Answer:B=Negative C=Positive D=Positive
Explanation:objects that repel each other means they have the same polarity. objects that attract have the opposite polarity A is negatively charged if A and B repel then A and B are both negative. B is negatively charged if B and C attract then they have reverse polarity which makes C positively charged. C is positive if C and D repel then that means that C and D have the same polarity making D positively charged.
Answer:
a force and a movement in the same direction as the force.
Explanation:
<span>The amplitude because that controls the height of the wave. Correct answer: Amplitude.</span>
Answer:
Newton's 3rd law of motion
Explanation:
According to the question, Newt noticed that It hurt his body more when he Jumped off a high diving board than It did when he Jumped off the lower board. What law of newton is this and why
By the time Newt want to jump, for him to do so, he has to push himself against the ground according to the Newton's 3rd law of motion.
The law states that in every action, there will be equal and opposite reaction.
The force at which he pushes himself against the ground will determine the force at which he will carry himself to jump off the high diving board.
The reaction towards the high diving board will be greater than the reaction towards the low diving board.
Therefore, Newt will hurt his body more when he Jumped off a high diving board than It did when he Jumped off the lower board. And the law of newton that is responsible for this is Newton's third law of motion.
As far as I remember, it usually takes more force to start an object sliding than it does to keep an object sliding because static friction is usually <span>greater </span>than sliding friction.
