If the wavelength<span> is given, the energy can be determined by first using the wave equation (c = λ × ν) to </span>find<span> the frequency, then using Planck's equation to </span>calculate<span> energy. Use the equations above to answer the following questions. 1. Ultraviolet radiation has a frequency of 6.8 × 1015 1/s.</span>
By definition, the speed of an object is given by:
Where,
dr/dt: derived from the position with respect to time
Therefore, speed has units of length over units of time.
Thus, speed is a derived quantity, since it depends on the value of two other quantities.
Answer:
a derived quantity is:
C. Speed
Answer:
The Answer Is A,C,D
Explanation:
The gravitational pull from the moon make bigger waves'
There would be no moon for eclipses
There would be more sun and no moon
Testable hypotheses could be developed for questions <em>B, D, and E</em> .
The main problem with A and C is the word "better". This is a rubber word. It means different things to different people, and it can mean different things to the same person at different times. It's always a matter of opinion, it has no unique units of measure, and there is no concrete way to measure it. Not good for developing a testable hypothesis.
The third hour was positive acceleration and the second hour was negative acceleration
