A merry-go-round is rotating at constant angular speed. Two children are riding the merry-go-round: Ana is riding at point A and
marysya [2.9K]

Answer:

bobby has a greater magnitude of velocity because because when angular speed is constant linear velocity is proportional to radius of the circular path

B. They both have same magnitude of angular velocity since the angular speed of the merrygoround is constant

C. Also they both have the same tangential acceleration because the angular speed is constant and tangential is zero for both of them

D. Centripetal acceleration of Bobby is greater

E.they both have the same angular acceleration because angular Speed I constant so angular acceleration is zero for both

A trout jumps, producing waves on the surface of a 0.8-mdeep mountain stream. If it is observed that the waves do not travel ups
alina1380 [7]

Answer:

The value is v  =  2.8 \  m/s

Explanation:

From the question we are told that  

     The depth of the mountain is  d =  0.8 \  m

Generally the  velocity of the surface  wave  is mathematically represented as

        v =   \sqrt{ g * d }      

=>      v =   \sqrt{ 9.8 * 0.8  }    

=>      v =   2.8 \  m/s

Generally using the Froude number is mathematically represented as

          Fr = \frac{ V }{ v }

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

            \frac{ V }{ v } > 1

=>         V  > v

=>         V  > 2.8 \  m/s

Hence the minimum velocity of the current  is  

            v  =  2.8 \  m/s

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
