Answer:
Explanation:
Data given
Maximum diffusion coefficient,
Activation Energy,
Temperature,T=713+273=986K
Universal gas constant, R=8.314J/mk
Since diffusion is the movement of particles from a higher concentration to a lower concentration, the coefficient of diffusion is expressed as
If we substittute valies we arrive at
Answer:
The answer is B. Avoid making a large wake.
Explanation:
When passing a fishing boat it is important to maintain a minimal wake due to the dangers a large wake could pose to the fishing boat you are passing, it is part of maintaining safety on the water.
You can not pass on the sides with the fishing lines also, and you are supposed to communicate to the fishing boat before taking the appropriate action.
Answer:
Explanation : Please go through the attached documents for the step by step solution.
Please note that, The file with the diagram is the first one and it is placed first.
Tempo decides the speed at which the music is played.
<u>Explanation:</u>
The Tempo of a bit of music decides the speed at which it is played, and is estimated in beats per minute (BPM). The 'beat' is dictated when mark of the piece, so 100 BPM in 4/4 compares to 100 quarter notes in a single moment.
A quick tempo, prestissimo, has somewhere in the range of 200 and 208 beats for each moment, presto has 168 to 200 beats for every moment, allegro has somewhere in the range of 120 and 168 beats for every moment, moderato has 108 to 120 beats for every moment, moderately slow and even has 76 to 108, adagio has 66 to 76, larghetto has 60 to 66, and largo, the slowest rhythm, has 40 to 60.
Explanation:
This question does not indicate the options to choose from, so I'll just outline the factors that determine if the nautical speed is safe for your boat.
When travelling with your boat, or just cruising around on your boat, It is necessary to consider the following factors before deciding if the speed you're travelling with is safe. These factors are:
1. <u>The weather and marine conditions</u>: One should calculate for the wind speed and direction, the water current, and the general condition of the water body.
2. <u>The traffic density on the water at that instance</u>: You should be mindful of other vessels on the water body before choosing your safe speed. The area available, and the proximity of these vessels to your boat should be considered
3. <u>Visibility</u>: The degree of visibility is a very important factor when determining what speed is safe for you. The speed should be chosen such that there is enough room and time to easily maneuver in order to prevent collision with an obstacle. Visibility can be impaired by fog, mist and cloudiness.
4. <u>The responsiveness of your vessels</u>: The ease with which your vessel responds to sudden change in direction should be considered. You shouldn't travel at a high speed if your boat is slow to respond to being maneuvered.
5. <u>Other navigational hazards</u>: Other navigational facilities and their proximity like buoys should be accounted for when choosing your vehicle speed.
Other factors includes:
draft of the vessel, limitations of radar equipment, and the wake your vehicle will leave at this speed.
From these listed factors, I think you should be able to pick out your answer.
