Explanation:
Antinodes are not the same thing as the amplitude , but they are very closely related. The amplitude is the distance from the rest position of the wave to the antinode . The antinode is just a point along the wave that has the greatest maximum velocity in the y-direction.
The amplitude of a standing wave doesn't remain the same throughout the wave. It keeps on changing as it is a function of x.
Where the amplitude is minimum is called?
The locations at which the absolute value of the amplitude is minimum are called nodes, and the locations where the absolute value of the amplitude is maximum are called antinodes.
C because you can't control the sun moving across the sky and therefore is not testable in an experiment.
Answers:
a) 198,55 s
b) 4687.98 m
Explanation:
a) Speed is defined as the variation of the position (distance traveled )of a body or object with time :
(1)
We are told the cheetah runs a distance of with a speed (Knowing and ), and we need to find the time it takes to travel that distance.
This means we have to find from (1):
(2)
(3)
(4)
b) Now, if we want to know the distance the cheetah will cover with in , we have to isolate from (1):
(5)
(6)
Finally:
Answer:
<em>waxing gibbous moon</em>
<em>It comes a week after new moon. <u>A waxing gibbous moon</u> occurs when more than half of the lit portion of the Moon can be seen and the shape increases ("waxes") in size from one day to the next. The waxing gibbous phase occurs between the first quarter and full moon phases.</em>
