Answer:
0.027 J
Explanation:
The formula of the potential energy in electrostatic (U) is
![U = q \times E \times d](https://tex.z-dn.net/?f=U%20%3D%20q%20%5Ctimes%20E%20%5Ctimes%20d)
The values given in the question are
Charge : q = ![4.5 \times 10^{-5} C](https://tex.z-dn.net/?f=4.5%20%5Ctimes%2010%5E%7B-5%7D%20C)
Electric Field strength : E = ![2.0 \times 10^{4} N/C](https://tex.z-dn.net/?f=2.0%20%5Ctimes%2010%5E%7B4%7D%20N%2FC)
Distance : d is 0.030 m
Insert in the formula , will give us
![U = 4.5 \times 10^{-5} C \times 2.0 \times 10^{4} N/C \times 0.030 m](https://tex.z-dn.net/?f=U%20%3D%204.5%20%5Ctimes%2010%5E%7B-5%7D%20C%20%5Ctimes%202.0%20%5Ctimes%2010%5E%7B4%7D%20N%2FC%20%5Ctimes%200.030%20m)
Further solving it
![U = 0.027 J](https://tex.z-dn.net/?f=U%20%3D%200.027%20J)
Which is the required answer.
Thanks
Explanation:
F net = 2+6-4 ( 2 and 6 N are in same direction so they get added, 4N in opposite direction so it will be subtracted)
F net=4 N
Answer:
0.8 x 10^-9 kg
Explanation:
Given,
Distance ( R ) = 10 m
Force ( F ) = 3.2 x 10^-9 N
Mass ( m1 ) = 40 kg
To find : Mass ( m2 ) = ?
Formula : -
F = m1.m2 / R^2
m2 = FR^2 / m1
= 3.2 x 10^-9 x 10 / 40
= 3.2 x 10^-9 / 4
= ( 3.2 / 4 ) x 10^-9
m2 = 0.8 x 10^-9 kg
Answer: because the ice was cold, and it melted in the tea. So the tea is now cooler.

Answer: Hi!
A neuron is a basic working unit of the brain. Neurons are special cells designed to transfer information to other nerve, muscle, or gland cells. They are pretty cool - looking too! (A slightly irregular circular shape with branches reaching out from all sides.) A neuron is a nerve cell. Nerve cells are the way of communication in the nervous system.
Hope this helps!
