A, most non metals are insulators
<h3>answer</h3>
The minimum velocity required for a object to rotate in a verticle plane is v
1
=
5
gr.
So, at bottom point, T
max
=mv
1
2
/r+mg=6mg.
At top-most point velocity is v
2
=gr.
So, T
min
=mv

/r−mg=0
So T

−T
min
=6mg=2×g⇒m=1/3 kg
V=IR can be changed to V/R=I so 10V/2 ohms = 5amps so 5 amps is your answer boss
A. a bicycle chain is an example of a compound machine
Answer:
2.145×10^-10 V or 0.2145nV
Explanation:
From hf=eV
h= Plank's constant = 6.6×10^-34JS
f= frequency of the electromagnetic wave = 5.2×10^4 Hz
e= electronic charge= 1.6×10^-19 C
V= voltage
V= hf/e
V= 6.6×10^-34JS × 5.2×10^4 Hz/ 1.6×10^-19 C
V= 2.145×10^-10 V or 0.2145nV
Therefore the voltage created is 2.145×10^-10 V or 0.2145nV
