Physical fitness is your ability to carry out tasks without undue fatigue. Learn about the components of physical fitness: cardio respiratory endurance, muscle strength, muscle endurance, flexibility and body composition and why they are important.
Answer:
See solution below
Explanation:
The standard equation of a wave is represented by: Y = Asin 2π(x/λ – ft)
A is the amplitude
λ is the wavelength
f is the frequency
t is the time
Comparing the standard with the given equation Y = 0.005sin 2π(0.5x – 200t)
i) A = 0.005m
Amplitude is 0.005m
ii) ω = 2πf
ω = 2π(200)
ω = 400π rad/s
iii) ω = 2πf
400π = 2πf
200 = f
Swap
f = 200Hertz
iv) Period = 1/f
Period = 1/200
Period = 0.005secs
v) wave number =
vi) Wavelength λ
0.5x = x/λ
0.5 = 1/λ
λ = 1/0.5
λ = 2m
vii) velocity - fλ
velocity = 200 * 2
velocity = 400m/s
To solve this problem, let us consider that the Earth is the
origin, the initial reference point. Therefore the speed of rocket plus the
missile would be 0.8 C
Now after the rocket had moved away from Earth, it fired a missile
at a speed of 0.7 C. Now the reference made to this is relative to the rocket.
We have established that our initial reference point is the Earth, therefore
the real speed of the missile with reference to Earth is:
Speed of missile relative to Earth = 0.8 C + 0.7 C
Speed of missile relative to Earth = 1.5 C
