Answer:
24.26 m/s
Explanation:
= Linear density of string = ![\dfrac{m}{L}=\dfrac{0.5}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7Bm%7D%7BL%7D%3D%5Cdfrac%7B0.5%7D%7B3%7D)
T = Tension on the string = mg = ![10\times 9.81](https://tex.z-dn.net/?f=10%5Ctimes%209.81)
g = Acceleration due to gravity = 9.81 m/s²
Velocity of a string is given by
![v=\sqrt{\dfrac{T}{\mu}}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cdfrac%7BT%7D%7B%5Cmu%7D%7D)
![\Rightarrow v=\sqrt{\dfrac{10\times 9.81}{\dfrac{0.5}{3}}}](https://tex.z-dn.net/?f=%5CRightarrow%20v%3D%5Csqrt%7B%5Cdfrac%7B10%5Ctimes%209.81%7D%7B%5Cdfrac%7B0.5%7D%7B3%7D%7D%7D)
![\Rightarrow v=24.26\ m/s](https://tex.z-dn.net/?f=%5CRightarrow%20v%3D24.26%5C%20m%2Fs)
The velocity of the wave is 24.26 m/s
Try this suggested solution; note, the answers are underlined with red colour.
Work= force*distance
Work= x*12
Force= mass*acceleration
Force= 5 kg*6
Force= 40 N
Work= 40×12
Work= 480 J (joules)
I think this is it
Answer:
mass=weight/gravitational acceleration
mass=1.059/10=105.9
Hence, internal energy in cylinder B is twice than that in A.
It is given that two cylinders contain the same ideal gas and have the same volume. If the gas molecules in cylinder B have twice the average kinetic energy as those in cylinder, we need to compare internal energy.
As kinetic energy is directly proportional to temperature, internal energy is also proportional to temperature.
We can say that more the average kinetic energy, more is the internal energy.
Hence, internal energy in cylinder B is twice than that in A.
The ratio in A:B is 1:2.
