Answer:
The electric field does positive work on the charge.
The potential energy associated with the charge decreases.
Explanation:
We know that force due to electric filed on a charge particle q given as
F = q E --------1
If the positive charge is moving in the direction of electric filed it means that force due to electric field and displacement of particle due to motion is in the same direction.So the work done due to electric filed will be positive.
Work = Force . Displacement
W= F.d
F= W/d ---------2
From equation 1 and 2
W/d = q E
W/ q = E/ d
We know that voltage difference ΔV
ΔV = E/ d
ΔV =W/ q
So the potential difference will be decrease because charge is positive.So the potential energy will be decreases.
Answer: The correct answer is "Reflection".
Explanation:
Reflection is the phenomenon in which the light ray gets reflected from the surface without getting transmit or absorb. It bounces back from the surface.
There are two laws of reflection.
(1) The angle of reflection is equal to the angle of incidence.
(2) The reflected ray, the incident ray and the normal lie in the same plane.
When you see your image on the surface of the water in a pond, the reflection phenomenon is at work.
Therefore, the correct answer is "Reflection phenomenon".
I would c is the best answer. As someone who is closed to multiple cultures, I know that gender roles are not necessarily the same across all cultures. Male-female friendships are definitely easier to develop now than in the past. I also know plenty of males who are very in touch with their emotions. Personally, when making friends, I tend to talk to the people with similar interests, simply because then I actually have something to talk about and it’s not awkward.
Answer:
As g=0 at the centre of earth the time period becomes infinite as T=2pi/underoot g. At center of earth, r = 0 & hence g = 0. Time period of a simple pendulum is T = 2π sqrt (1/g).
