For a point charge, how does the potential vary with distance from the point charge, r?
a constant
b. r.
c. 1/r.
d. 
.
e. 
.
Answer:
The correct option is C
Explanation:
Generally for a point charge the electric potential is mathematically represented as
Here we can deduce that the electric potential varies inversely with the distance i.e
So
Answer: 16 μC
Explanation: In order to solve this problem we have to reduce to the equivalent capacitor for the initial conection:
see the attach field to details.
Answer:
Depth of the pool, h = 4.004 cm
Explanation:
Pressure at the bottom, P = 39240 N/m²
The density of water, d = 1000 kg/m³
The pressure at the bottom is given by :
P = dgh
We need to find the depth of pool. Let h is the depth of the pool. So,
h = 4.004 m
So, the pool is 4.004 meters pool. Hence, this is the required solution.
Hi!
We call these stars <em>main sequence </em>stars. Main sequence stars actually make up around 90% of the stars in our universe!
An interesting thing to note is that our sun is actually a <em />yellow dwarf star, which is a <em>small </em>main sequence star.
Hopefully, this helps! =)
Answer:
Kinetic Theory states that pressure is not cause by molecule that push molecule to each other
Explanation:
Kinetic Theory
it is also known as kinetic molecular theory or the collision theory
Kinetic theory explain you property of gas such as
(1) pressure, (2) temperature, (3) volume
Kinetic Theory states that pressure is not cause by molecule that push molecule to each other and pressure is caused by molecule colliding with the each other and with the container
3 component of
kinetic theory are
-
when the molecules collide, there no energy is gain or lost
- In the gas molecule take approx negligible amount of space
- molecules are in constant and linear motion
