Answer:
Force is defined as the push or pull on a body which changes or tends to change the state of rest or uniform motion in a straight line.
The SI unit of force is Newton (N)
<h3>
Further more information:</h3>
Simply, pull or push is called force. A book lying on the table continues to lie on the table unless and external force is applied in it. So, Generally force is an external agency which changes or tends to change the state of rest to motion or vice versa. The SI unit of force is Newton. In CGS system, the unit of force is dyne.

- It can change the speed of the body.
- It can change the direction of motion of body.
- It can change the shape of the body.
- It can change the position of the body.
Hope this helps...
Good luck on your assignment...
$10,350 is the amount of money that has been collected mangoes are sold by Anya and Lauren at $15.
Number of mangoes of Anya's = 115 mangoes
Number of mangoes of Lauren's = 5 × 115 = 575 mangoes
Total number of mangoes = Number of mangoes Anya has + Number of mangoes Lauren has
= 115 + 575
= 690 mangoes
Amount each mango sold = $15
The total amount of money collected = Total number of mangoes × Amount each mango were sold
= 690 × 15
= $10,350
So, therefore, Anya and Lauren sold their total mangoes for $10,350.

Answer:
-320 μJ.
Explanation:
Consider a point with an electrical charge of . Assume that is the electrical potential at the position of that charge. The electrical potential of that point charge will be equal to:
.
Keep in mind that since both and might not be positive, the size of the electrical potential energy might not be positive, either.
For this point charge,
- ; (that's -8.0 microjoules, which equals to )
- .
Hence its electrical potential energy:
.
Why is this value negative? The electrical potential energy of a charge is equal to the work needed to bring that charge from infinitely far away all the way to its current position. Also, negative charges are attracted towards regions of high electrical potential. Bringing this negative charge to the origin will not require any external work. Instead, this process will release 320 μJ of energy. As a result, the electrical potential energy is a negative value.
