The frequency of a tuning fork that takes2.50×10⁻³ s to complete one oscillation would be 400 Hz.
<h3>What is the frequency?</h3>
It can be defined as the number of cycles completed per second. It is represented in hertz and inversely proportional to the wavelength.
As given in the problem a tuning fork takes 2.50×10⁻³ s to complete one oscillation.
Frequency = 1/time period of the oscillation
Frequency of the tuning fork = 1/time period
=1/2.50×10⁻³
=400 Hz
Thus the frequency of a tuning fork comes out to be 400 Hz.

Answer:
0.025 Meters a second, or 0.025 m/s
Explanation:
So, if we take the information that we know, 1) The wall is 2 meters thick, and 2) it took a total of 0.05 seconds to travel all the way. So, to get our answer, lets divide 0.05 by 2. That lands us with 0.025! This answer makes sense, because we know that sound travels quickest in solids, (Due to sound-waves being a mechanical longitudinal wave, and solids have the densest particle formations, allowing the sound wave to travel swiftly compared to liquids and gases, in which the particles are more spread out.)
Answer:
The average induced emf in the loop is 0.20 V
Explanation:
Given:
Radius of loop 
m
Magnetic field 
T
Change in time 
sec
According to the faraday's law,
Induced emf is given by
Where 
magnetic flux
( here 
)
Where 
We neglect minus sign because it's shows lenz law
V
Therefore, the average induced emf in the loop is 0.20 V
C because in order to make something go faster you need to increase it's velocity
Explanation:
the speed of sound depends on the particles of the medium of the sound wave is moving through because the particles in the solid and tightly packed together South Wales weekly transfers energy from particle to particle in a solid
