Answer:
20N
Explanation:
Force applied by Samantha = 10N
Force applied by Emily = 10N
Since both Samantha pushes the box of textbook in the same direction; their forces are additive.
Net force applied on box = Force applied by Samantha + Emily
Force is a pull or push on a body
Net force = 10N + 10N = 20N
Constructive interference will occur, which means the waves will combine.
In destructive inference, the waves cancel each other out.
Hope this helps :)
Answer:
please tell me what does w.r mean ? then I will try to give answer
Answer: A. Object A will have a positive charge.
Explanation: If the number of protons and electrons are the same, their net charges cancel each other out, and you have a neutral charge. If electrons are transferred to another object, the amount of positive charge will outweigh the amount of negative charge. As a result, you are left with an overall positive charge in object A. Meanwhile, object B is now negative.
