Answer:
Twice
Explanation:
From the formula for velocity in a circle
V= 2πr/T
Where V is velocity
r is raduis
T is period
We see that as r increases V increases so if r is doubled V becomes doubled
Answer:
D) 31 m, 19 Hz
Explanation:
The equation of the wave in the problem is
In general, the equation of a travelling wave is written as
where
A is the amplitude
is the wave number, with being the wavelength of the wave
is the angular frequency and f is the frequency
By comparing the two equations, we see that for this wave:
So now we can use the two equations for k and to find the wavelength and the frequency of the wave:
forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion. friction: the force that opposes the motion or tendency toward motion of two objects that are in contact.
