A power plant uses 365 GJ/hr of energy from a boiler and extracts 18 GJ/hr as work from a turbine and rejects the remaining ener

ziro4ka [17]

Answer:

The rate of heat rejection will be 347 GJ/hr

Explanation:

We have given that power plant uses energy of 365 GJ/hr

So energy uses $Q_B=365GJ/hr$

Work done from turbine $W_T=18GJ/hr$

We have to find the rate of heat rejection to the atmosphere $Q_C$

We know that $Q_B=W_T+Q_C$

$365=18+Q_C$

$Q_C=347GJ/hr$

So the rate of heat rejection will be 347 GJ/hr

Sabe-se que um alqueire paulista equivale a 24200 metros quadrados. Uma chácara retangular tem um alqueire e mede 100m de frente

sattari [20]

Answer:

b = 242 m

Explanation:

A = 24200 m²

a = 100 m

b = ?

A seguinte fórmula é aplicada

A = a*b

⇒ b = A / a

⇒ b = (24200 m²) / (100 m)

⇒ b = 242 m

A certain aircraft can fly 612 miles with the wind in 3 hours and travel the same distance against the wind in 6 hours. What is

Andreas93 [3]

Answer:

51 mph

Explanation:

Given: A certain aircraft can fly 612 miles with the wind in 3 hours and travel the same distance against the wind in 6 hours.

Formula: $Speed=\dfrac{Distance}{Time}$

Let speed of aircraft be x mph and speed of wind y mph

Aircraft along wind:

Actual speed of aircraft = x + y

Time taken = 3 hours

Distance = 612 miles

$\therefore x+y=\dfrac{612}{3}$

$x+y=204----------(1)$

Aircraft against wind:

Actual speed of aircraft = x - y

Time taken = 6 hours

Distance = 612 miles

$\therefore x-y=\dfrac{612}{6}$

$x-y=102----------(2)$

By solving equation (1) and equation (2) and we get

x = 153 mph

y = 51 mph

Hence, The speed of wind will be 51 mph

What is the length of the blues progression in this excerpt?

Gre4nikov [31]

<span>In blues musicians also often refer to chord progressions using Roman numerals, as this facilitates transposing a song to a new key. For example, rock and blues musicians often think of the 12 bar blues as consisting of I, IV and V chords. Thus a simple version of the 12 bar blues might be expressed as I/I/I/I IV/IV/I/I V/IV/I/I. By thinking of this blues progression in Roman numerals, a backup band or rhythm section could be instructed by a band leader to do the chord progression in any key. For example if the band leader asked the band to play this chord progression in the key of C Major, the chords would be C/C/C/C F/F/C/C G/F/C/C.</span>
