Which motion maps show an object in uniform circular motion? Check all that apply. V W X Y
2 answers:
Explanation:
In this case we need to say that out of the attached figure which shows that the object is in uniform circular motion.
When and object moves in a circular path, its motion is called circular motion. In this type of motion, the speed of the object remains constant while its position changes i.e. its velocity changes.
Out of attached options, V shows circular motion, as the object is position continuously. W and Y are similar cases.
So, V, X and Y shows the circular motion of the object. Hence, this is the required solution.

Answer:
Explanation:
We need 2 different equations for this problem: first the velocity of sound equation, then the frequency of the sound equation.
The velocity of sound is found in:
v = 331.5 + .606T
We need to find that first in order to fill it into the frequency equation which is
where v is the velocity we will find the part a, f is frequency and lambda is the wavelength. Starting with the velocity of the sound:
v = 331.5 + .606(25) and
v = 331.5 + 15 and rounding correctly using the rules for sig fig when adding:
v = 347 m/s
Filling that into the frequency equation:
and
so
