Answer:
45.13 beats/min
Explanation:
Speed of space vehicle = 0.51c
the pulse rate measured by the astronaut= 61.0 beats per minute
Pulse rate measured by the Earth observer is given by
putting vales we get
= 45.13 beats/min
The electron has the least mass
Answer:
0.2286 m, 0.686 m and 1,143 m
therefore we see that there is respect even where the intensity is minimal
Explanation:
Destructive interference to the two speakers is described by the expression
Δr = (2n +1) λ/2
where r is the distance, λ the wavelength and n an integer indicating the order of the interference
let's locate the origin on the left speaker
let's find the wavelength with the equation
v = λ f
λ = v / f
we substitute
Δr = (2n + 1) v / 2f
let's calculate for difference values of n
Δr = (2n +1) 343/(2 750)
Δr = (2n + 1) 0.2286
we locate the different values for a minimum of interim
n Δr (m)
0 0.2286
1 0.686
2 1,143
therefore we see that there is respect even where the intensity is minimal
Answer:
well I don't know if this answers your question but the moon moves or orbits around the earth at the same time with the sun from some info I got
