Answer:
We say that the object's spectrum is shifted.
Explanation:
Spectral lines will be shifted to the blue part of the spectrum1 if the source of the observed light is moving toward the observer, or to the red part of the spectrum when is moving away from the observer (that is known as the Doppler effect).
That shift can be used to find the velocity of the object by means of the Doppler velocity.
(1)
Where is the wavelength shift, is the wavelength at rest, v is the velocity of the source and c is the speed of light.
Answer:
Interviewing and observation are two methods of collecting qualitative data as part of research. ... Interviews vary from structured, in which a set list of questions is asked of every interviewee, to unstructured, which is open-ended.
This problem is pretty straight forward since we are given
the half time and we simply have to find for the rate constant. The equation
relating the two variable is:
t1/2 = ln(2) / k
where k is the rate constant, therefore:
k = ln(2) / t1/2
k = ln(2) / 14.7 h
<span>k = 0.047 / hour</span>
Acceleration = force / mass = 8/10 m/s^2
After 5 s (from the start) velocity = 5 x 8/10= 4 m/s
