ength: 150 cm C. Amplitude: 30 cm; wavelength: 200 cm D. Amplitude: 150 cm; wavelength: 30 cm
2 answers:
Answer: The amplitude is 15 cm and wavelength is 150 cm.
Explanation:
The wavelength is the distance between two consecutive compression.
The amplitude is the maximum displacement of the wave.
According to the figure,
This wave is longitudinal wave.
So, The amplitude is 15 cm approximate.
Now, the wave length will be
The wavelength is the distance between two consecutive compression is
Hence, The amplitude is 15 cm and wavelength is 150 cm.

Answer:
(a) T = 2987.6 k
(b) T = 19986.2 k
Explanation:
The temperature of a star in terms of peak wavelength can be given by Wein's Displacement Law, which is as follows:
where,
T = Radiated surface temperature
= peak wavelength
(a)
here,
= 970 nm = 9.7 x 10⁻⁷ m
Therefore,
<u>T = 2987.6 k</u>
(b)
here,
= 145 nm = 1.45 x 10⁻⁷ m
Therefore,
<u>T = 19986.2 k</u>
Answer:
A) 15.0 years
Explanation:
Due to the distance to the star system is in light-year units, we can compute the time by using:
then, Rob will take to complete the trip about 15 light-years.
hope this helps!!
