Answer:
3.2m
Explanation:
Given parameters:
Frequency of the FM radio = 9.23 x 10⁷Hz
Velocity of the waves = 3 x 10⁸m/s
Unknown:
Wavelength of the wave = ?
Solution:
To solve for the wavelength of the wave, we need the velocity equation;
Velocity = frequency x wavelength.
Radio waves are all electromagnetic radiations produced by both electrical and magnetic fields perpendicularly oriented to one another.
Since the unknown is wavelength, we solve for it:
3 x 10⁸ = 9.23 x 10⁷ x wavelength
wavelength = 
wavelength = 3.2m
The force between two objects is calculated through the equation,
F = Gm₁m₂/d²
where m₁ and m₂ are the masses of the objects. In this case, an unknown mass and Earth. d is the distance between them and G is universal gravitation constant.
In the second case, if the force is to become 2.5 times the original and all the variables are constant except d then,
2.5F = Gm₁m₂ / (D²)
D = 0.623d
Subsituting the known value of d,
D = 0.623(6.9 x 10^8) = <em>4.298 x 10^8 m</em>
If you double the velocity you would have to halve the magnetic field strength to keep the force on the particle the same and hence the trajectory.
F = qvB
The isotope notation for the isotope of iodine that has 67 neutrons is 
<h3>Meaning of Isotope</h3>
Isotopes can be defined as an element members that all have the same number of protons but different numbers of neutrons.
Isotopes possess the same number of protons in a nucleus and this is what defines the element's atomic number.
In conclusion, The isotope notation for the isotope of iodine that has 67 neutrons is
