We know, W = k. q₁q₂/ [1/r₁² - r₂² ]
Here, r₁ = R
r₂ = ∞
Substitute their values,
W = k. q₁q₂/ [1/R - 1/∞]
W = k. q₁q₂/ [1/R]
W = k. q₁q₂/ R
Hope this helps!
Answer:
wavelength is equivalent to the velocity divided by the frequency
Option C is the right answer
Answer:
The pressure inside the hose 7000 Pa to the nearest 1000 Pa.
<em></em>
<em></em>
The pressure at the site of the puncture is <em></em>
Explanation:
<em>According to Poiseuille's law, </em>
<em>Where is the pressure at a point before the leak, is the pressure at the point of the leak , μ = dynamic viscosity, L = the distance between points and , Q = flow rate, D = the diameter of the garden hose. </em>
<em>Also, from the equation , the equations and can be derived.</em>
Combining Poseuille's law with the above, we get
<em></em>
<em></em>
Since the hose has a uniform diameter, the nozzle at the end is closed and neither point <em> nor lie after the puncture,</em>
<em></em>
The pressure at the site of the puncture <em></em>
<em></em>

The correct answer is:
<span>B) orange, yellow, green, blue
the energy of the photons of light is directly proportional to the frequency of the light. This means that the lower the frequency, the lower the energy, and the higher the frequency, the greater the energy.
Therefore, the order in increasing energy is exactly the same as the order in increasing frequency, which is:
