Answer:

$Power = 2.5kW$

Explanation:

Given

$Mass = 200kg$ -- mass of tub

$Energy = 200,000J$

$Time = 80s$

Required

Determine the amount of power needed

Power is calculated as thus:

$Power = \frac{Energy}{Time}$

Substitute values for Energy and Time

$Power = \frac{200,000J}{80s}$

$Power = 2500W$

Divide by 1000 to convert to kW (kilowatt)

$Power = 2.5kW$

The number of kilowatts used by an individual to operate his appliances is determined as 12.1 kWh.

<h3>Average daily power consumption</h3>

The average daily power consumption is the amount of electric energy consumed by an individual on a daily rate.

The average daily power consumption of individuals in USA is 12,100 W-hr.

<h3>Converting watts to kilowatts</h3>

E = 12,100 Whr/1000

E = 12.1 kWh

Thus, the number of kilowatts used by an individual to operate his appliances is determined as 12.1 kWh.

A piston-cylinder device initially contains 0.3 kg of nitrogen gas at 160 kPa and 140oC. The nitrogen is now expanded isothermal

irakobra [83]

Answer:

<h2>Work done by the gas is given as</h2><h2> $W = 1.72 \times 10^4 J$ </h2>

Explanation:

As we know that the process is isothermal so here work done is given as

$W = nRTln(\frac{P_1}{P_2})$

here we know that

$n = \frac{w}{M}$

$n = \frac{300}{28} = 10.7 moles$

now we have

$W = 10.7 (8.31)(273 + 140) ln(\frac{160}{100})$

so we have

$W = 1.72 \times 10^4 J$

Convert 3.5revolutions to radians.

olga55 [171]

As we know that

$1 revolution = 2\pi radian$

now we know that

$3.5 revolution = 3.5 rev\times \frac{2\pi rad}{1 rev}$

$3.5 rev = 21.98 rad$

so it is 21.98 radian
