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.

Answer:
Impulse = 10.36 kg m/s
average force = 172.667 N
Explanation:
given data
mass = 0.280 kg
speed = 15.0 m/s
speed = 22.0 m/s
to find out
impulse and magnitude of the average force
solution
we know that Impulse is change in momentum that is
initial momentum = mass × speed ..........1
initial momentum = 0.28 × (15)
initial momentum = 4.2 kg m/s
Final momentum = mass × speed ..........2
Final momentum = 0.28 × (-22)
Final momentum = -6.16 kg m/s
so now we get Impulse that is
Impulse = 4.2 - (-6.16)
Impulse = 10.36 kg m/s
and
average force will be
average force = impulse ÷ time
average force = 
average force = 172.667 N

Explanation:
potential energy is stored energy that an object has due to its position or chemical composition. Since the truck has the possibility to move down the hill when it is at the top of the hill, it has a great amount of potential energy, howver when its at the bottom of the hill, it doesn’t have the possibility to move or can move v little due to its positions, therefore it has little to no potienatal energy.
Answer: 7 kg bowling ball must move with a speed of 2.8 m/s so that it has the same kinetic energy.
Explanation:
Kinetic energy is the energy possessed by a body by virtue of its motion.
m = mass of object
v= velocity of the object
b) for a 7 kg bowl to have kinetic energy of 27 Joules:
Thus 7 kg bowling ball must move with a speed of 2.8 m/s so that it has the same kinetic energy
