Using the equation E = hc/λ we can find out how much energy a single photon of wavelength 193 nm has. E = Planck Constant * Speed of Light/193 nm
Answer:
d
Explanation:
30 minutes = 50 km/h * 5 =250km/h
Answer: False
Explanation:
The statement that the environment affects people, but people don't affect the environment is incorrect. It should be noted that people also affect the environment.
Some of our impact on the environment include pollution, deforestation, overpopulation, burning of fossil fuels etc. Thus has resulted in changes such as erosion, climate change, etc.
Answer:
If the third charge is placed at a distance the net force on the charge will be zero
Explanation:
<em>Consider the diagram below.</em>
<em>Let us add a new charge Q at a distance b from the origin.</em>
<em />
Let the force that the charge 2Q exert on the new charge (Q) be
Let the force that charge -Q exerts on the new charge be
For the third charge in equilibrium,
Solving this will give us a quadratic equation which will be further simplified.
Making b the subject of the formula, we can get the distance that the third charge will be placed .
So if the third charge is placed at a distance the net force on the charge will be zero
<em>if real values were plugged in, it will be easier for us to determine the value of b</em>
