Answer:
(a) 2800 J
(b) 31.28 %
Explanation:
Heat intake, Q1 = 8950 J
Heat discard, Q2 = 6150 J
(a) Work = intake heat energy - discarded heat energy
W = Q1 - Q2 = 8950 - 6150 = 2800 J
(b) Efficiency = 1 - Q2 / Q1
Efficiency = 1 - (6150 / 8950) = 0.3128 = 31.28%
<span>It changes from a liquid into a solid which means it is changing states. It also is changing temperature due to the condenser increasing or decreasing the temperature in order for the vapor to be transformed in liquid.</span>
Michael Faraday first discovered Electromagnetic Induction in 1830. His experiment that proved this the following: H<span>e moved a permanent magnet in and out of a coil or a single loop of wire. And it induced an </span>Electro M<span>otive </span>F<span>orce or </span>emf. In other words, the moving magnet produced a Voltage, and therefore a current. Michael Faraday’s famous law gives answer of the question of the dependence of the voltage: T<span>he magnitude of the voltage is proportional to the rate of change of the flux. It is false that the voltage can not be increased by moving a magnet towards a coil. It is increased.</span>
T he role of oxygen in air supply is to keep all the ling beings live and healthy.
<h3>What is Oxygen?</h3>
Oxygen is the most important gas required for the living of human beings, animals, birds and the whole ecosystem.
Oxygen is fundamental for breath on the grounds that the body utilizes it to 'consume' food atoms. Creatures take in oxygen while breathing in and radiate carbon dioxide while breathing out. Oxygen makes up practically 21% of the all out gases in air, with the majority of the excess gas being physiologically latent nitrogen.
Oxygen assumes a basic part in breath, the energy-delivering science that drives the digestion systems of most living things. We people, alongside numerous different animals, need oxygen in the air we inhale to remain alive. Oxygen is created during photosynthesis by plants and many sorts of organisms.
Thus, the air supply needs oxygen on the majority.
