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:
I think its radiation
Explanation:
Conduction is the transfer of heat through solids (A)
Convection is the transfer of heat through liquids or gasses (B)
Radiation is the transfer of heat through em waves (C)
Answer: A BaBr2
Explanation:
On the left side of the equation, the superscript 2 is applied to both sodium AND bromine. That means you need 2 bromine on the right. Also on the left side, the 2 AFTER chlorine only applies to the chlorine so there’s only one barium. What you have on the left has to balance with what you have on the right.
Answer:
C should be the correct answer,
Explanation:
The gas which produce heat in the atmosphere as it is increased is called a greenhouse gas. Gases like argon , nitrogen, and Oxygen etc. is not a greenhouse gas. Since O3 is not a greenhouse gas it cannot produce heat in the atmosphere .
Hope you understand,
The webbing on a duck's foot creates a larger surface area, which means the force of its weight is distributed over more surface area and therefore there is less pressure on the mud and its not likely to be displaced as much, so the foot doesn't get stuck.
