Answer: OPTION A
Step-by-step explanation:
We need to remember that Product of powers property, which states that:
Let's check the options:
A. For 
you can apply the property mentioned before. Then:
(It is the equivalent expression)
B. Add the exponents:
(It is not the equivalent expression)
C. For 
you can apply the property mentioned before. Then:
(It is not the equivalent expression)
D. We know that 
and we maje the addition indicated in this option, we get:
(It is not the equivalent expression)
True, because energy, frequency, and wavelength are all properties of sound, and sound is an electromagnetic wave. The electromagnetic spectrum encompasses a continuous range of frequencies or wavelengths of electromagnetic radiation, ranging from long wavelength, low energy radio waves to short wavelength, high frequency, high energy gamma rays.
r = √(3V/πh)
multiply both sides by 3 to eliminate the fraction
πr²h = 3V ( divide both sides by πh )
r² = 3V/ πh ( take the square root of both sides )
r = √(3V/πh)
Answer:
5/3
Step-by-step explanation:
Since the given figure is a rectangle with congruent diagonals and thus equal lengths, you can use the expressions for the diagonal lengths, set them equal, and solve the equation for x.
