Answer:
Net charge produce due to presence of different chargers in the vicinity or in the considered region.
Explanation:
Net electric charge is just a concept introduce to identify the result of the presence of number of charges which interact with each other. It can be found by treating electric chargers in algebraic form like numbers, where +charges get added with +charges
-charges get added with -charges
and when adding two charges with opposite signs they get subtracted and the symbol of the resultant charge comes from the charge with highest magnitude.
(a) The velocity ratio of the screw is 1570.8.
(b) The mechanical advantage of the screw is 785.39.
<h3>
Velocity ratio of the screw</h3>
The velocity ratio of the screw is calculated as follows;
V.R = 2πr/P
where;
- P is the pitch = 1/10 cm = 0.1 cm = 0.001 m
- r is radius = 25 cm = 0.25 m
V.R = (2π x 0.25)/(0.001)
V.R = 1570.8
<h3>Mechanical advantage of the screw</h3>
E = MA/VR x 100%
0.5 = MA/1570.8
MA = 785.39

As per Dalton's model of atom he said that atom is indivisible and it can not be further divided into sub atomic parts
so atom is the most fundamental part of any matter
so here we can say that as per his theory of atom we have an atom is like the system of positive and negative charge not exist separately and we can't get it in free state
so here the correct way to show his model is by
<em>b) a solid sphere </em>
The answer is cesium oxide
The so-called greenhouse effect is observed only in houses painted green, and even there, only between the hours of 2PM - 4PM local time on Thursday afternoon.
