<span>The last statement does not represent one of Koch's postulate, that is, the postulate did not include determination of how long it takes for the healthy animal to become ill. Koch's postulate established four criteria for determining the causative organism for a particular disease. The criteria are: the causative organism must be present in all cases of the disease, the causative organism must be isolated from the diseased host and grown in pure culture, the causative organism from the pure culture must cause the disease when inoculated into a health susceptible animal and the causative organism must be re-isolated from the new host and proof to be the same as the original causative organism inoculated into the health animal.</span>
<em>Average velocity is defined as the ratio of change in position to the time taken for that change. </em>
Answer: <em>True</em>
Explanation:
Velocity is obtained by dividing the displacement of an object by time interval. Displacement is a vector quantity which is defined as the shortest distance between initial and final point of an object.
In other words, displacement is the change in position of an object. A position-time graph can be plotted to find the average velocity of an object graphically. The average velocity can be obtained by calculating the slope of the position-time graph.
While average velocity deals with velocity over a particular time interval, instantaneous velocity gives the velocity of an object at a particular point of time or instant.
Colors seen on the cover of our physics book result from color is due to Subtraction.
What is physics of color subtraction?
- Some visible spectrum wavelengths are intentionally removed during the subtraction procedure.
- For instance, the yellow filter transmits the green and red colors while blocking the blue.
- Red and blue are transmitted while the green is blocked by the magenta filter.
- Blue and green are transmitted while red is blocked by the cyan filter.
- Subtractive mixing gets its name from the fact that when colors are mixed, wavelengths are removed from what we see because each paint absorbs some of the wavelengths that the other paint reflects, leaving us with less wavelengths afterward.
