Answer:
a
![\lambda = 1.18 \ m](https://tex.z-dn.net/?f=%5Clambda%20%20%3D%201.18%20%5C%20%20m)
b
![v = 77.172 \ m/s](https://tex.z-dn.net/?f=v%20%20%3D%20%2077.172%20%5C%20%20m%2Fs)
c
![T = 151.41 \ N](https://tex.z-dn.net/?f=T%20%20%3D%20151.41%20%5C%20%20N)
Explanation:
From the question we are told that
The frequency is ![f = 65.4 \ Hz](https://tex.z-dn.net/?f=f%20%3D%20%2065.4%20%5C%20%20Hz)
The length of the vibrating string is ![L = 0.590 \ m](https://tex.z-dn.net/?f=L%20%20%3D%20%200.590%20%5C%20%20m)
The mass is ![m = 15.0 \ g = 0.015 \ kg](https://tex.z-dn.net/?f=m%20%20%3D%20%2015.0%20%5C%20g%20%20%3D%20%200.015%20%5C%20%20kg)
Generally the wavelength is mathematically represented as
![\lambda = 2 * L](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%202%20%2A%20%20L)
=> ![\lambda = 2 * 0.590](https://tex.z-dn.net/?f=%5Clambda%20%20%3D%20%202%20%2A%20%20%200.590)
=> ![\lambda = 1.18 \ m](https://tex.z-dn.net/?f=%5Clambda%20%20%3D%201.18%20%5C%20%20m)
Generally the wave speed is
![v = \lambda * f](https://tex.z-dn.net/?f=v%20%20%3D%20%20%5Clambda%20%20%2A%20%20f)
=> ![v = 1.18 * 65.4](https://tex.z-dn.net/?f=v%20%20%3D%20%201.18%20%2A%2065.4)
=> ![v = 77.172 \ m/s](https://tex.z-dn.net/?f=v%20%20%3D%20%2077.172%20%5C%20%20m%2Fs)
Generally the tension on the wire is mathematically represented as
![T = v^2 * \frac{ m }{L }](https://tex.z-dn.net/?f=T%20%20%3D%20%20v%5E2%20%20%2A%20%20%5Cfrac%7B%20m%20%7D%7BL%20%7D)
=> ![T = 77.172 ^2 * \frac{ 0.015 }{0.590}](https://tex.z-dn.net/?f=T%20%20%3D%20%2077.172%20%5E2%20%20%2A%20%20%5Cfrac%7B%20%200.015%20%20%7D%7B0.590%7D)
=> ![T = 151.41 \ N](https://tex.z-dn.net/?f=T%20%20%3D%20151.41%20%5C%20%20N)
Answer:
a=4,32m/s^2
Explanation:
Fnet = F1 - F2
= 12-1.2
= 10.8N
m=2.5kg
Fnet =ma
10.8=2.5a then divide both sides by 2.5 to get acceleration
Answer:
Well, their are two answers in their. It would be Ask their Parent for assistance in persuading and Ask for an opportunity to earn extra credit:)
Explanation:
The two fields were physical quantities are used in motion calculations are length and mass with time.
The physical quantity in a field is referred as every point in a particular space time.
<h3>
How physical quantities are used in motion calculations?</h3>
If we consider an object, the physical property of the object is considered as physical quantity and to measure that object is known as units. The Physical quantity can be classified as elemental physical quantity and derived physical quantity. Length, mass, time, etc.. are elemental physical quantity, momentum, density, acceleration, etc... are derived physical quantity. Only for charge and temperature the physical quantity will be less than zero.
Length, mass and time are the physical quantities used in motion calculations.
