Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the eq
lawyer [7]

Answer:

The value of rate of decrease of volume = - 3600 \frac{k pa}{min}

Step-by-step explanation:

According to Boyle's law P V = C ------- (1)

Pressure ( P ) = 100 k pa = 10 \frac{N}{cm^{2} }

Volume ( V ) = 900 cm^{3}

Put these values in equation ( 1 ) we get,

⇒ C = 10 × 900 = 9000 N-cm = 90 N-m

Differentiate Equation ( 1 ) with respect to time we get,

⇒ V \frac{dP}{dt} + P \frac{dV}{dt} = 0

⇒ V \frac{dP}{dt} = - P \frac{dV}{dt}

⇒ \frac{dV}{dt} = - \frac{V}{P} \frac{dP}{dt} ---------- (2)

This equation gives the rate of decrease of volume.

Given that Rate of increase of pressure = \frac{dP}{dt} = 40 \frac{k pa}{min}

C = 90 N-m

P =  10^{5} pa = 10 \frac{N}{cm^{2} }

V = 900 cm^{3}

Put all the above values in equation 2 we get,

⇒  \frac{dV}{dt} = - \frac{900}{10} × 40

⇒  \frac{dV}{dt} = - 3600 \frac{k pa}{min}

This is the value of rate of decrease of volume.

You are a business owner and you want to know if you have made a profit
Gennadij [26K]

Answer: Yes the business made a profit for the month. They made $90,000 net profit. They made a profit of $90,000 after all the taxes were deducted.

Step-by-step explanation: 200 times $1000 = $200,000. $200,000 - $50,000 = $150,000. $150,000 - $40,000 = $110,000. $110,000 - $20,000 = $90,000
