Answer:
<u>So the correct answer is letter e)</u>
Explanation:
The electric field of an infinite yz-plane with a uniform surface charge density (σ) is given by:

Where ε₀ is the electric permitivity.
<u>As we see, this electric field does not depend on distance, so the correct answer is letter e)</u>
I hope it helps you!
Answer:
Yes
Explanation:
A position describes the position of an object relative to the x/y-axis (or the four cardinal directions). A velocity is a vector quantity, defining speed with direction.
So if an object is in a positive position, it means they are in the positive x-axis direction (or wherever on the scale the positive values are stated to be) and if it has a negative velocity, it means said object is moving in the opposite direction of the positive x-axis. It is possible for the object to still be in the positive position as it's moving with a negative velocity
Answer:
The time required to send the data from Earth to Moon will be 1.28s while for a two way communication, to send it back to the earth, it will take double time i.e. <em>RTT = 2.56s </em>
Explanation:
Distance between Earth and Moon = 385,000 km = 3.85 x 10⁸m
Speed of data travel = speed of light ≈ 3 x 10⁸m/s
As, v=d/t
t=d/v

t=1.28s
RTT = Double of single way time taken = 2x1.28
<em><u>RTT=2.56s</u></em>

For transverse waves, the waves move in perpendicular direction to the source of vibration.
For longitudinal waves, the waves move in parallel direction to the source of vibration .
They are similar in the sense that energy is transferred in the form of waves.
-
Difference:
-
Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave.
Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.
The given question is incomplete. The complete question is as follows.
Two identical balls each have a mass of 35.0 grams and a charge of q = 3.50 \times 10^{-6}C[/tex]. The balls are released from rest when they are separated by a distance of 6.00 cm. What is the speed of each ball when the distance between them has tripled? Use k =
.
Explanation:
According to the conservation of energy, the formula will be as follows.

or, ![\frac{kq_{1}q_{2}}{r_{1}}[1 - \frac{1}{3}] = mv^{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bkq_%7B1%7Dq_%7B2%7D%7D%7Br_%7B1%7D%7D%5B1%20-%20%5Cfrac%7B1%7D%7B3%7D%5D%20%3D%20mv%5E%7B2%7D)
Putting the given values into the above formula as follows.
![\frac{kq_{1}q_{2}}{r_{1}}[1 - \frac{1}{3}] = mv^{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bkq_%7B1%7Dq_%7B2%7D%7D%7Br_%7B1%7D%7D%5B1%20-%20%5Cfrac%7B1%7D%7B3%7D%5D%20%3D%20mv%5E%7B2%7D)
= 23.333
v = 4.83 m/s
Thus, we can conclude that speed of each ball when the distance between them has tripled is 4.83 m/s.
