A transfer of charge is actually a gross movement of electrons. Charged objects have a normal or "balanced" state. This state is balanced in a sense of positive charges (protons) and negative charges (electrons). When an object has an excess of deficiency of electrons, it will try to regain its balance by releasing or accepting electrons.
Answer:
Mass is zero if the whole rope is horizontal. Imaginary rope.
Explanation:
With any mass at all, only a small section of the rope will be truly horizontal. The rope curve will be a a catenary.
Answer:
The work done is 85200 J or N•m
Explanation:
Here,
Force = 200 N
Distance = 426 m
Now, For work done
<h3><u>Formula</u><u>:</u></h3>
<u>Work = Force × Distance.</u>
W = F × d
W = 200 × 426
W = 85200 J or N•m
Thus, The work done is 85200 J or N•m

Answer:
0.33m/s²
Explanation:
Given parameters:
Initial velocity = 19.9m/s
Final velocity = 4.4m/s
Time = 47.6s
Unknown:
Acceleration = ?
Solution:
To solve this problem, we use the expression below:
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Acceleration =
Acceleration = -0.33m/s²
This is a deceleration
