If mass remains the same while the volume increases, the density of the substance will decrease.
If mass remains the same while the volume decreases, the density of the substance will increase.
Hertz, which is a unit for frequency (f), also means 1/second. Hence, the speed (S) of wave is the product of its wavelength (n) generated per second (frequency). The speed of the given wave above is,
S = nf ; S = (45 m) x (9 / s) = 405 m/s
Hence, the speed of the wave is 405 m/s.
You’ll need 4H20 molecules to balance the equation.
Kinetic Energy = 1/2mv^2
The solution is attached below.
Answer:
Transverse wave- Back and forth at right angles to the direction of the wave arrow.
longitudinal wave- bask and forth in the direction of the motion of the motion of the wave.
electromagnetic wave- two alternating waves moving at right angles to each other.
Explanation:
In a longitudinal wave, the particles vibrate at right angles in reference to the wave motion.
In a transverse wave, the particles vibrate parallel to the wave motion
Electromagnetic waves occur as a result of the interaction between two waves and are normally transverse in nature.
