The radio station z107.7 broadcasts radio waves. What do the numbers 107.7 represent?
2 answers:
Answer : The number 107.7 represent the frequency.
Explanation :
Frequency : It is defined as the number of oscillations per second. the S.I unit of frequency is, Hertz (Hz)
Formula of frequency is,
where,
f = frequency
t = time period
Radio frequency : It is the rate of oscillation of electromagnetic radio waves within the range of 3 kHz to 300 GHz.
Therefore, the number 107.7 represent the frequency.

Answer:
Neutrons.
Explanation:
Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of nucleons).
The isotope of an element is denoted by
Where; X is the symbol of the element.
A is the atomic mass or number of nucleons.
Z is the atomic number or number of protons.
<em>Therefore, the number of neutrons = A - Z</em>
<em>Isotopes of carbon differ with respect to the number of neutrons.</em>
<em>Basically, there are three (3) Isotopes of Carbon and these are;</em>
<em>1. Carbon-12: it has an atomic mass of 12 with 6 numbers of proton and neutron respectively. </em>
<em>2. Carbon-13: it has an atomic mass of 13 with 6 numbers of proton and 7 numbers of neutron. </em>
<em>3. Carbon-14: it has an atomic mass of 14 with 6 numbers of proton and 8 numbers of neutron. </em>
