1 MHz --- 1 000 000 Hz
99.5 MHz --- x
x = 99 500 000 Hz = 99,5x10^6 Hz
v = λ . f
c = λ . f
3x10^8 = λ . 99,5x10^6
λ = 3x10^8 / 99,5x10^6
λ ≈ 0,0302x10^2
<em>λ ≈ 3,02 m</em>
i think is the letter (B), isn't it?
the answer on edginuity is B- Fluids (i just took the test)
1. A complete fitness and exercise program should incorporate three basic components: Endurance (Aerobic), Flexibility, and Strength. Each of these components has specific guidelines, which govern their effectiveness
I would say the number of harmonics decrease, because you're adding to the frequency of a wave.
I hope this helps :)
The mass of the aeroplane is 300,000 kg.
<h3>What is Newton's second law of motion?</h3>
It states that the force F is directly proportional to the acceleration a of the body and its mass.
The law is represented as
F =ma
where acceleration a = velocity change v / time interval t
Given is the aeroplane lands at a speed of 80 m/s. After landing, the aeroplane takes 28 s to decelerate to a speed of 10 m/s. The mean resultant force on the aeroplane as it decelerates is 750 000 N.
The force expression will be
F = mv/t
Substitute the values and we have
750000 = m x (80 -10)/ 28
750,000 = m x 2.5
m = 300,000 kg
Thus, the mass of the aeroplane is 300,000 kg.
