Frequency = (speed) / (wavelength)
= (3 x 10⁸ m/s) / (300 m)
= 1 x 10⁶ per sec
= 1 mHz
This frequency is the " 1000 " or " 100 " that's marked
in the middle of your AM radio dial.
If there's an AM station in your city that broadcasts on 1000 kHz
and you tune your radio to it, you're picking up radio waves
that are 300 meters long. (about 0.19 of a mile)

Explanation:
Electronegativity is the property of an atom that attracts the shared pair of an electron to itself. There is a trend in the periodic table.
While moving down in a group, the electronegativity decreases. This is due to the reason that as we move down the number of shells added and so the electron become very far from the pull of the nucleus.
As we move across a period the electronegativity increases. This is because of the no. of charge on the nucleus increase.
Frequency because all the other things may have to do with energy but frequency is the one that has to do with number of wavelength passed by a certain point or a certain time
Answer:
Explanation:
Time of flight is the time taken by the bulet in air. Time of flight is expressed as T = Usinθ/g where;
U is the initial velocity = 180m/s
θ is the angle of launch = 90° (Since the bullet is shot upwards)
g is the acceleration due to gravity = 9.81m/s²
T = 180sin90/9.81
T = 180/9.81
T = 18.35s
<em>Hence the bullet will spend 18.35s in air</em>
<em></em>
The height covered by the bullet is the maximum height. Maximum height is expressed as;
H = u²sin²θ/2g
H = 180²sin²90/2(9.81)
H = 180/19.62
H = 9.17m
<em>Hence the bullet will go 9.17m high</em>
