Answer:
Mercury,Venus,Earth and Mars
Explanation:
Answer:
The kinetic energy K of the moving charge is K = 2kQ²/3d = 2Q²/(4πε)3d = Q²/6πεd
Explanation:
The potential energy due to two charges q₁ and q₂ at a distance d from each other is given by U = kq₁q₂/r.
Now, for the two charges q₁ = q₂ = Q separated by a distance d, the initial potential energy is U₁ = kQ²/d. The initial kinetic energy of the system K₁ = 0 since there is no motion of the charges initially. When the moving charge is at a distance of r = 3d, the potential energy of the system is U₂ = kQ²/3d and the kinetic energy is K₂.
From the law of conservation of energy, U₁ + K₁ = U₂ + K₂
So, kQ²/d + 0 = kQ²/3d + K
K₂ = kQ²/d - kQ²/3d = 2kQ²/3d
So, the kinetic energy K₂ of the moving charge is K₂ = 2kQ²/3d = 2Q²/(4πε)3d = Q²/6πεd

This is the Correct Answer.
Knowing about distance between a gun fired and it's target is very useful for accurate shot.
It might be useful to know the distance between a gun fired and it's target because it gives us information about the angle at which the target has been hitting. If we do not know about distance between a gun fired and it's target, we can't shot the target accurately.
So we can conclude that knowing about distance between a gun fired and it's target is very useful for accurate shot.

B. orange
C. red
D. violet
The longest wavelength within the visible spectrum is red light. The correct option is C.
The visible spectrum of light consists of different colors ranging from red to violet. Each color corresponds to a different wavelength. Among the given options, red light has the longest wavelength within the visible spectrum.
A. blue: Blue light has a shorter wavelength compared to red light. It is located on the shorter end of the visible spectrum.
B. orange: Orange light has a shorter wavelength compared to red light. It falls between red and yellow on the visible spectrum.
C. red: Red light has the longest wavelength among the visible colors. It is located on the longer end of the visible spectrum.
D. violet: Violet light has a shorter wavelength compared to red light. It is located on the shorter end of the visible spectrum, just after blue.
Therefore, the correct option is C. red as it has the longest wavelength within the visible spectrum.
