a steam engine work on its vicinity 285 k heat is released with the help of 225 c energy absorbed to the system what is the effi
zvonat [6]

The efficiency of steam engine is  26.66 %.

<h3>What is Efficiency?</h3>

The efficiency is defined as the work done by the engine divided by the heat supplied.

Work done is the difference between the heat supplied and heat rejected.

So, efficiency η = (Qs -Qr) / Qs

Given is the heat supplied Qs = 225 Joules and heat rejected Qr =285 . then the work done is

W = 225 -225 = - 60 Joules

Efficiency η  = 60/225 x 100%

η = 26.66 %

Thus, the efficiency of the steam engine is  26.66 %.

Learn more about efficiency.

Which of these elements have the strongest and the weakest forces between its atoms.Give A Reason For Your Answer. Copper,oxygen
vredina [299]

Answer:

Copper is the correct answer

Explanation:

Copper is very strong in situations where it is put in place and not stressed. Like all metal products, you can tear a whole in a copper pipe when it is under constant stress. That might seem obvious, but the thing about using it as pipe material is that some people try to cheat and bend copper into place if they don't measure properly and wind up with a piece that is bit too big or a bit too small.

Hope it helps pls mark me as BRAINLIST :)

What frequency corresponds to a period of 4.31s.<br> T =1/f = 1/4.31s = 0.232hz correct?
Korvikt [17]

Answer:correct

Explanation: Period T is the reciprocal of frequency (i.e T=1/f)

Frequency is the reciprocal of period (i.e F= 1/T)

Therefore if T=4.31s

Frequency F= 1/4.31s=0.232hz

Technician A says printed circuit boards may become "etched" if touched with bare hands. Technician B says printed circuit board
Crank

Answer:

Both technicians are correct.

Explanation:

Printed circuits boards are copper layers attached to a dielectric plane with some design on it. This design is made to direction the current flow through a predefined path or electrical circuit. This way is easier to interconnect electronic devices instead of using cables for each connection.

Since the printed circuit board PCB its made of cooper, touching the printed circuit board may cause in the middle term corrosion and even rust, because the cooper in touch with the salt, sweat, and other stuff from the fingerprints can react in the metal surface, creating corrosion.
