Answer:
speed = 8.57mph while v = 0 mph
Explanation:
The horse is running 1 mile in 7 minutes. Then for a total of 1 hour, 60 minutes, the horse should be able to run a distance of
So the horse speed is 8.57 miles per 60 minutes, or 8.57 mph (mile per hour). But if he ends up at the same point as before int he oval track, one can argue that the displacement is 0, and so is its velocity.
When supernova explodes
because of the collapsing cores, the core itself will become a neutron star or
a white dwarf without undergoing any kind of explosive transformation. The white
dwarf stars can also become supernova if they orbit another star in a binary
system and steal material from their companion. In addition, the end state of a
star, whether it will explode as a supernova become a black hole.
Answer:
The sine waves of the two waves should look the same.
Explanation:
The sine wave formula for a sound wave is given as
y = A sin[2πft + θ]
where
y = The displacement of the wave at time t.
A = amplitude or maximum displacement of the wave during its progression.
t = time
f = frequency of the wave
θ = phase angle/phase shift of the wave which is normally 0 for sound waves
From this information,
It is evident that it is the frequency and time that dictate the exact motion of the wave or behaviour of the waveform. The amplitude only dictates the extent of the wave.
And if the frequency of 2 waves A and B are similar, then even a very different Amplitude cannot change the fact that the two waves will behave similarly, have the same sine curve and have the same movements as the time of progression increases.
Even if the phase angle isn't zero, whatever it is, will not change the fact that the two waves will appear similar to each other, only separated by that phase angle.
Hence, the two waves will look very similar with only the amplitude that shows the extent of displacement, different.
Hope this Helps!!!
True: a scientific fact is something that is absolute and unchanging.
The amount of matter in an object is called its, mass. How much the mass weights would be referred to as weight
