The perceived pitch of a tone is largely determined by its frequency
<h3>
What is frequency ?</h3>
The frequency of a repeated event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to underline differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is stated.
The period is the reciprocal of the frequency since it is the length of time for one cycle in a repeating occurrence. If a heart beats 120 times per minute (2 hertz), for instance, its period, T—the space between beats—is half a second. In science and engineering, frequency is a crucial metric for describing the temporal rate of change seen in oscillatory systems.

There are mistakes in the question.The correct question is here
A 2.0 kg, 20-cm-diameter turntable rotates at 100 rpm on frictionless bearings. Two 500 g blocks fall from above, hit the turntable simultaneously at opposite ends of a diameter, and stick. What is the turntable’s angular velocity, in rpm, just after this event?
Answer:
w=50 rpm
Explanation:
Given data
The mass turntable M=2kg
Diameter of the turntable d=20 cm=0.2 m
Angular velocity ω=100 rpm= 100×(2π/60) =10.47 rad/s
Two blocks Mass m=500 g=0.5 kg
To find
Turntable angular velocity
Solution
We can find the angular velocity of the turntable as follow
Lets consider turntable to be disk shape and the blocks to be small as compared to turntable
where I is moment of inertia
Answer: Salt
Explanation: Alkenes, esters, and salts are all functional groups either containing or being functional groups.
The two sides of the aluminium pop can have opposite charges. Overall the can is electricity neutral; it's just that the positive and negative charge has been separated from each other. We can say that the charge in the can has been polarized. In general terms, polarization means to separate into opposites.
HOPE IT HELPS!!!!!!
plz mark as a brainliest answer!!!!!
A solution is two things mixed together...Like water and sand. The universal solvent is water, so a solution is not a colloid. Solvents take over another compound.
