Answer:
59.19%
Explanation:
Step 1:
Data obtained from the question. This include the following:
Input temperature = 495 K.
Output temperature = 293 K.
Efficiency =..?
Step 2:
Determination of the efficiency of the engine.
Efficiency is simply defined as the ratio of output to input times 100. Mathematically, it is expressed as:
Efficiency = output /input x 100
With the above formula, we can calculate the efficiency of the engine as follow:
Input temperature = 495 K.
Output temperature = 293 K.
Efficiency =..?
Efficiency = output /input x 100
Efficiency = 293/495 x 100
Efficiency = 59.19%
Therefore, the efficiency of the engine is 59.19%
The affinity of hemoglobin for oxygen is <u>increased</u> as the partial pressure of oxygen is raised.
Hemoglobin is the most vital constituent of red blood cells.
It is a kind of protein found in red blood cells that transfers oxygen to all parts of your body.
Hemoglobin is made up of proteins called 'heme' to which oxygen molecules become attached and travel throughout the body.
The blood carrying oxygen is called oxygenated blood and when it reaches the lungs, oxygen molecules detach and brings carbon dioxide along to remove it from the body through respiration.

Answer:
<u>Work done</u><u> </u><u>is</u><u> </u><u>5</u><u> </u><u>J</u>
Explanation:
Workdone = Force × distance
Answer:
486nm
Explanation:
in order for an electron to transit from one level to another, the wavelength emitted is given by Rydberg Equation which states that
Hence the photon must possess a wavelength of 486nm in order to send the electron to the n=4 state
It is the ratio of distance an object moves to the amount of time needed to travel the distance.
