<span>The reason why the balloon shrunk is because as the balloon gets cooler, the molecules lose energy and move closer together causing the balloon to shrink.</span>
7. The charged object can have two polarities, positive or negative which is determined by the configuration of electron orbitals of the material. If there are free orbitals, it will likely gain electrons and produce a negative charge. If there are free electrons on the outermost orbitals, these electrons will be lost and the material will have a positive charge.
8. R<span>ubbing styrene and rabbit fur because rabbit fur has free orbitals which can hold electrons making styrene positive.
9. When it is dry and windy.
10. When there no other materials that can take or add electrons from or to it.
11. Static charge is dissipated through static electricity.

To answer this you multiply the N (which is 300 in this case) by m (or 5). This will give you 1500
The answer is A) It uses less energy to make something from recycled materials than from new materials.

Given parameters:
Initial velocity of eraser = 5.0m/s
Time = 7.0s
Unknown:
Final velocity = ?
Solution:
Since we have been given the initial velocity and duration of the throw, we can apply the appropriate motion equation to solve this problem.
V = U - 2gt
where V is the final velocity
U is the initial velocity
g is the acceleration due to gravity = 9.8m/s²
t is the time taken
V = U - gt
V = 5 - (9.8)(7)
V = -63.6 or -64m/s
The velocity is -64m/s
