"Period" and "frequency" of waves and oscillations are simple reciprocals. They're not related to the wavelength or speed.

Period = 1 / frequency

Period = 1 / 23.4 Hz

<em>Period = 0.043 second</em>

What is the power of a machine that transfers 15,000J of energy in 1 minute?

____ [38]

Answer:

answer is 250 W

Explanation:

W=P * t

t=60s

W= 15000J

15000= P * 60

P= 15000/60

P= 250W. (SI unit of power Watt)

A frictionless piston-cylinder device contains 4.5 kg of nitrogen at 110 kPa and 200 K. Nitrogen is now compressed slowly accord

pochemuha

Answer:

427.392 kJ

Explanation:

m = Mass of gas = 4.5 kg

Initial temperature = 200 K

Final temperature = 360 K

R = Mass specific gas constant = 296.8 J/kgK

$\gamma$ = Specific heat ratio = 1.5

Work done for a polytropic process is given by

$W=\frac{mR\Delta T}{1-\gamma}\\\Rightarrow W=\frac{4.5\times 296.8(360-200)}{1-1.5}\\\Rightarrow W=-427392\ J\\\Rightarrow W=-427.392\ kJ$

The work input during the process is -427.392 kJ
