Answer:
C. amplitude = 0.10 m, wavelength = 0.60 m
Explanation:
The diagram shows an oscillating progressive wave, with its amplitude and wavelength.
Amplitude of a wave is the maximum distance covered either upward or downward.
So that,
amplitude of the wave, A =
= 0.1
Amplitude of the wave = 0.1 m
Wavelength in this case is the distance from crest to crest, or trough to trough of the wave.
So that,
wavelength =
= 0.6
wavelength of the wave = 0.6 m
Therefore, the amplitude of the wave is 0.10 m, while the wavelength is 0.60 m.
Since the rabbit is moving at constant velocity, therefore
the acceleration is zero, hence the increase in distance over time would simply
be:
x = v t
where v is velocity and t is time, x is distance
Since we are starting at x = 8.1 m, the equation of motion
would therefore be:
<span>x = 8.1 – 1.6 t</span>
Answer:
Speed of the wave in the string will be 3.2 m/sec
Explanation:
We have given frequency in the string fixed at both ends is 80 Hz
Distance between adjacent antipodes is 20 cm
We know that distance between two adjacent anti nodes is equal to half of the wavelength
So
We have to find the speed of the wave in the string
Speed is equal to
So speed of the wave in the string will be 3.2 m/sec
Friction the force that oppose motion so it unhelpful where all the motion of an object is desired.that is what i know.
Answer:
a great, disapprove.
Explanation:
We are most likely to experience cognitive dissonance if we feel a great sense of responsibility for engaging in behaviors of which we personally disapprove.
Cognitive dissonance is psychological term meaning a state of mind when having inconsistent thoughts, beliefs, or attitude, generally conflicting in nature. For example, when people smoke ( behavior), knowing already that smoking causes cancer, they are in state of cognitive dissonance.
