The frequency of radio waves at the two stations are:
1. WIL-92.3 : Frequency = 92.3 MHz (mega hertz)
2. KSHE-94.7 : Frequency = 94.7 MHz
The wavelength (λ) and frequency (ν) are related as:
ν = c/λ ------(1)
Energy (E), frequency (ν) and wavelength (λ) are related as:
E = hν -----(2)
(or)
E = hc/λ ----(3)
A) Based on equation (2), higher the frequency higher is the energy. Therefore, station KSHE broadcasts waves with higher energy
B) Based on equation (1), higher the frequency lower will be the wavelength. Station KSHE will broadcast waves with shorter wavelength
C) KSHE will broadcast waves with higher frequency
When it contains both a solute and a solvent it is called a solution
Answer:
The correct option is;
Waves that move through the Earth
Explanation:
In attempting to unravel the nature and arrangements of the rocks beneath the Earths surface, Geologist apply numerous methodologies including seismological field survey and analysis whereby the time of travel of natural (due to events such as earthquakes) or man made (during geological exploration) seismic wave are analysed to image the nature, composition and dynamism of the Earth's interior to find out the presence of geological faults or liquid layers as well as to predict the possible occurrence of future events within the Earth's crust in detail.
Answer:
The answer to your question is 14.3 %
Explanation:
Data
volume of ethanol = 50 ml
volume of water = 300 ml
volume percent = ?
Formula
Percent by volume = (volume of solute/volume of solution) x 100
Volume of solute = 50 ml
volume of solution = 300 + 50 = 350
Substitution
Percent by volume = (50/350) x 100
Simplification and result
Percent by volume = 14.3 %
