Answer:
The value is
Explanation:
From the question we are told that
The depth of the mountain is
Generally the velocity of the surface wave is mathematically represented as
=>
=>
Generally using the Froude number is mathematically represented as
Here V is the velocity of the current
Given that the waves do not travel upstream, then the flow of the current is supercritical which means that
=>
=>
Hence the minimum velocity of the current is
This because the velocity of the current is greater velocity of the surface wave , so minimum will be like the lowest possible value of V which is v
Answer:
- the bucket-surface area vector and the direction of the rain is 180° which gives a negative flux in the outward direction.
- If we cut the base of the bucket then hold it in the rain then the there is no area intercepted by the rainfall and hence we have a zero flux.
Explanation:
We know that flux is defined as the density of any energy field passing through a given area parallel to the area vector.
Mathematically:
where:
flux through the area
area of concern
density of energy field per unit area
angle between the energy field lines and the normal to area.
When we hold a bucket in the rain then assuming that the base of the bucket is normal to the direction of rainfall then the angle between the area vector and the rain drop is zero when observed from inside.
- For the flux outside the bucket we are concerned with the outer surface of the bucket, now the angle formed between the bucket-surface area vector and the direction of the rain is 180° which gives a negative flux in the outward direction.
- If we cut the base of the bucket then hold it in the rain then the there is no area intercepted by the rainfall and hence we have a zero flux.
