Answer:
Correct answer is Wave A has a greater pitch and frequency
Explanation:
To understand the given figure, we should know the definition of wavelength, frequency and pitch
Wavelength
wavelength is defined as distance between two successive wave crests or troughs.
Frequency
Frequency is defined as the number of waves which passes through a given point per second. SI unit of frequency is Hertz.
Pitch
our ear understand the frequency of a sound wave as pitch. A a lower frequency sound has a lower pitch and a higher frequency sound has a higher pitch.
In given figure Wave A has lower wavelength and higher frequency so it have higher pitch than wave B.
Answer:
F1= 588 N
F2= 784 N
Explanation:
Please see the attached file.
<span>The correct answer is option B. i.e UV Rays. The Ultra violet light is the part of electromagnetic light whose wavelength is less than the Visible light light. i.e. UV range is from 10 nm to 400 nm. UV light is invisible to the naked eye.</span>
ANY force causes an object to accelerate, just as long as there are not
some other forces on the object that cancel out the first one.
Are you looking for the answer ... an "UNBALANCED" force ?
That's a very poor way to describe it, because there's no such thing
as a balanced or unbalanced force. The thing that's balanced or
unbalanced is a GROUP of forces, not a single force.
You must find the component of the force before calculating
