Answer:
C. Beats
Explanation:
When waves are interfering with each other, the sound is louder in some places and softer in others. As a result, we hear pulses or beats in the sound.
Answer: the wavelength of this transition is 1.2039 um
Explanation:
Given that;
the energy level between the transitioning energy gap Eg = 1.0 + 0.03 = 1.03 eV
we know that λ = 1.24 / Eg
so we substitute our Eg into the above equation
λ = 1.24 / 1.03
λ = 1.2039 um
therefore the wavelength of this transition is 1.2039 um
Answer:
We use X-rays to help the injured, Radiowaves to communicate or entertain, and Visible light to see.
Answer:
3.66m/s^2
Explanation:
First, we need to find the friction which is F=u*N.
After that, find the resultant force by substarcting the friction from the forward force.
Lastly,using the formula F=ma, substitute in the known values of F and m to find a
Answer:
The answer is choice A.
Explanation:
Assuming you are in a situation with a gravitational field. You can divide the motion of the bullet into two components. One horizontal and the other in the vertical.
