Answer:
0.5 m
Explanation:
Two charges each of magnitude q
Let the third charge is Q is placed at a distance x from the origin so that the charge is in equilibrium.
The force on Q due to q at origin is balanced by the charge on Q due to the charge q placed at x = 1 m.
So,
1 - x = x
1 = 2x
x = 0.5 m
Thus, the third charge is placed at x = 0.5 m .
If you are choosing to get a digital photo album it can come with the advantages like, it’s more economically friendly because you’re not having to print out pictures. But it’s disadvantage is that you can lose it easily or accidentally delete it some way. You also have a choice of a physical photo album, it’s advantages are that you won’t lose it as easily and they might last longer than a digital one’s. It’s disadvantage though is that with all the pictures and the book to keep the pictures in takes a lot from the economy. A solution to the digital photo album is to save in on a hard drive or something like that so you can keep it without having to worry about it being deleted as easily. The solution with the physical photo album is that you could get a photo holder that you can slide picture into pockets because it will keep the pictures from damage as well as using less paper products.
you can read over it and change things i might have done wrong and if i completely missed the point of this i’m sorry and hope you have a good day/night. (also it’s 6 sentences)
1. Frequency: 
The frequency of a light wave is given by:
where
is the speed of light
is the wavelength of the wave
In this problem, we have light with wavelength
Substituting into the equation, we find the frequency:
2. Period: 
The period of a wave is equal to the reciprocal of the frequency:
The frequency of this light wave is (found in the previous exercise), so the period is:
B. When the ball is rolling across the floor at a constant velocity, the change in its kinetic energy is zero.
<h3>
What is change in kinetic energy?</h3>
The change in kinetic energy of an object is the dereference between the final kinetic energy and the initial kinetic energy.
ΔK.E = K.Ef - K.Ei
ΔK.E = 0.5m(vf² - vi²)
where;
- K.Ef is the final kinetic energy
- K.Ei is the initial kinetic energy
- vf is final velocity
- vi is initial velocity
At constant velocity, the initial velocity and final velocity are equal.
ΔK.E = 0.5m(0) = 0
Thus, when the ball is rolling across the floor at a constant velocity, the change in its kinetic energy is zero.
