With the advent of the plastic balloon and the beginning of the unmanned ... That would lead to a more sophisticated ballast system that uses fine steel or iron
Answer:
<em>b. The force is 6 times the original</em>
Explanation:
<u>Coulomb's Law
</u>
The electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:
Where:
q1, q2 = the objects' charge
d= The distance between the objects
Suppose one of the charges is doubled, i.e., q1=2q1 and the other charge is tripled (q2'=3q2). The new force F' would be:
Operating:
Substituting the original value of the force:
b. The force is 6 times the original
Answer:
(a) = 3910
(b) = 5181
(c) = 2762955 m
Explanation:
Using equations of uniformly accelerated motion:
Equations:
-
-
(a) Using equation 1:
⇒ Because it upward from rest
(b) Using equation 1:
⇒ Because is the is the initial speed in the movement before changing acceleration
(c) Using equation 2:
⇒ and Because it upward from rest
⇒
