Answer:
0.87 m
70.6 Hz
Explanation:
= length of the rope = 1.30 m
= order of the harmonic = 3
= Wavelength
Wavelength is given as
= 0.87 m
= Speed of transverse wave = 61.4 m/s
= frequency of the third harmonic
frequency is given as
= 70.6 Hz
Answer:
Explanation:
From the question we are told that
Piston-cylinder initial Volume of air
Piston-cylinder initial temperature
Piston-cylinder initial pressure
Supply line temperature
Supply line pressure
Valve final pressure
Piston movement pressure
Piston-cylinder final Volume of air
Piston-cylinder final temperature
Piston-cylinder final pressure
Generally the equation for conservation of mass is mathematically given by
where
Initial moment
Final moment
Work done by Piston movement pressure
Heat function
Therefore
It is given mathematically that the system lost or dissipated Heat of
Answer:
The work done on the system can be accounted for by;
Both and
Explanation:
The speed of the crate = Constant
Therefore, the acceleration of the crate = 0 m/s²
The net force applied to the crate, = 0
Therefore, the force of with which the crate is pulled = The force resisting the upward motion of the crate
However, we have;
The force resisting the upward motion of the crate = The weight of the crate + The frictional resistance of the ramp due to the surface contact between the ramp and the crate
The work done on the system = The energy to balance the resisting force = The weight of the crate × The height the crate is raised + The heat generated as internal energy to the system
The weight of the crate × The height the crate is raised = Gravitational Potential Energy =
The heat generated as internal energy to the system =
Therefore;
The work done on the system = +
