A. the object’s motion does not change.
sukhopar [10]
Answer:
D. the object accelerates

Explanation:
Based on Newton's first law: "An object will maintain its state of rest or motion unless an external force acts on it"
An unbalanced forced means that there is a net force acting on the object. This will lead the object to either speed up, slow down, come to rest or change its direction.
This means that the net force caused by the unbalanced force will lead the object to accelerate.

Hope this helps :)

Chen has 17CDs. She gives 2 to her brother and buys 4 more. Her brother gives her 1 and she gives 3 to her best friend. How many
d1i1m1o1n [39]

Answer: she has 17 CDs now.

Step-by-step explanation:

The total number of CDs that Chen had initially is 17.

She gives 2 to her brother. This means that she would be having

17 - 2 = 15

She buys 4 more. It means that she would be having

15 + 4 = 19

Her brother gives her 1. So the number that she has is

19 + 1 = 20

she gives 3 to her best friend. Therefore, the number of CDs that Chen has now is

20 - 3 = 17
