Answer
given,
total charge Q = 100 n C
= 100 × 10⁻⁹ C
radius of the solid sphere = 30 cm
= 0.3 m
Volume of sphere = 
= 
=0.113 m³
a) volume charge density

ρ = 8.85 × 10⁻⁷ C/m³
b) at r = 10 cm = 0.1 m
charge in the sphere at radius

= 3.7037 \times 10^{-9}C[/tex]
Field strength


= 
at r = 20 cm = 0.2 m





= 
at r = 30 cm


= 9.99 N/C
There are different kinds of conductors, most notably electrical and thermal conductors. But they are often inclusive of each other (electrical conductors are typically good thermal conductors).
A conductor transmits something through its body with high efficiency while an insulator does not transmit very well. In the case of electricity, a conductor transmits electrical energy between two points while an insulator blocks the flow of electricity.
Two examples of conductors are copper and silver. Two examples of insulators are wood and styrofoam.
Answer:
<h2>All of the work of life</h2>
Explanation:
In all works of life science can be applied, in-fact science has already been applied already, even in the humanities, social sciences and art related studies sciences is being applied,
Furthermore, the application of science and technology knows no boundaries, and as science is advancing day by day, expanding to new frontiers and breaking new limits so is it application to all works of life and relevance everyday.
Answer:
He is wrong!
Explanation:
Frequency refers to how many wave lengths pass in a second and speed is how fast the wave is traveling for example the speed of light goes really fast but has a mid-level frequency.
Hope this helps! ;-)
Angular velocity w is directly proportional to its velocity.
