You must operate the exhaust blower before
starting a boats inboard gasoline engine to remove fuel
vapors.
If you have not started the boat for some time, inspect the boat first
before running to check if there is any problem. Sometimes we thought there is
small problem but later it can cause a big problem.
<span>So you must look for the engine, fuel etc. these are all the
precautionary steps for our safety.</span>
Answer:
dark-field microscopy
Explanation:
A darkfield microscope can be regarded as a brightfield microscope with a significant modification to condenser. There is an opaque disk, with a diameter of about 1cm placed in between the illuminator and condenser lens, the disk responsible for the blocking of most of the light from the illuminator, passing through the condenser to objective lens , which will then form hollow cone of light that has its focus on the specimen. Using a darkfield microscope the light that get to the objective is the only refracted or reflected light of structures in the specimen. And the image formed usually display a bright object with a dark background.
It should be noted that darkfield microscope is a type of microscopy works by allowing only light waves that have reflected from or refracted though the sample to enter the lens system.
When he <span>determined that the drop time was inversely proportional to the horizontal velocity, the answer for it would be </span>Bob's conclusion was right because the data points were connected. The connection of the x and y axis varied because it is inversely proportional.
The statement that best describes an external circuit is "<span>D. The flow of an alternating current switches direction when a generator's terminals change its charge." The main difference between direct and alternating current is the direction of flow. Direct current follows only one direction from negatve to positive, while alternating current changes direction periodically.</span>
