Answer: 3
Wavelength = 0.76m
Explanation:
When sound wave is travelling at standard temperature and pressure ( STP), its speed will be equal to normal speed of sound which is equal to 331 m/s
Given that the period of the wave is 0.0023 seconds.
Wave speed = wavelength/period
Substitute the wave speed and the period to obtain wavelength
331 = wavelength/0.0023
Cross multiply
Wavelength = 331 × 0.0023
Wavelength = 0.7613 metre
The wavelength of this sound is closest to 0.76 m
Answer:
The value is 
Explanation:
From the question we are told that
The formula for the Electric potential difference is 
The current is 
The uncertainty of the current is 
The Resistance is 
The uncertainty of the Resistance is 
Taking the log of both sides of the formula
=> 
differentiating both sides
Here V is mathematically evaluated as
So from
![\Delta V = V * [\frac{\Delta I}{I} +\frac{\Delta R}{R} ]](https://tex.z-dn.net/?f=%5CDelta%20V%20%20%3D%20%20V%20%2A%20%5B%5Cfrac%7B%5CDelta%20I%7D%7BI%7D%20%2B%5Cfrac%7B%5CDelta%20R%7D%7BR%7D%20%5D%20)
![\Delta V = 183.21 [ \frac{0.3 }{9.3} + \frac{0.6}{19.7}]](https://tex.z-dn.net/?f=%5CDelta%20V%20%20%3D%20%20183.21%20%20%5B%20%5Cfrac%7B0.3%20%7D%7B9.3%7D%20%2B%20%5Cfrac%7B0.6%7D%7B19.7%7D%5D)

Answer:
Kinetic energy is the energy obtained from movement while potential energy is the energy in something when it is at a height or has been manipulated in some way; it has work done to it.
Explanation:
Kinetic energy is, like I said, energy gained through movement or action. When an object stops moving, it converts into a different type of energy. Energy cannot be destroyed or created. An object with potential energy has a reference. A reference determines how high it is. The higher and heavier an object is, the more potential energy it has.
Hope this helps!
