Q: 6) (2 pts) A monkey and a goat are riding on a merry-go-round that is turning at

option A is correct pressure is less in partiallyy blocked region because according to bernoulli's P + 0.5 rho *v^2 = P0 + 0.5 rho *v'^2 according to eqn of continuity AV= A1v' as we can see area at blocked region is less and hence velocity become more and as velocity increses K.E energy gets increases so Po will goes down.

Question

6) (2 pts) A monkey and a goat are riding on a merry-go-round that is turning at a constant rate. The monkey is near the outer edge, and the goat is closer to the center Who has the greater angular speed? A) Both have the same non-zero angular speed. B) Both have zero angular speed. C) the monkey D) the goat 7) (2 pts) A chicken and a donkey are riding on a merry-go-round that is turning at a cons tant rate. The chicken is near the outer edge, and the donkey is closer to the center. Who has the greater tangential or linear speed? A) Both have the same non-zero tangential speed B) Both have zero tangential speed. C) the chicken D) the donkey 8) (2 pts) A toy boat sinks in a swimming pool containing a purple liquid but floats in a normal pool containing water. Therefore, you can conclude that A) the toy boat is denser than water. B) the purple liquid is denser than water. C) water is denser than the purple liquid. D) It is impossible to determine using the information given. 9) (2 pts) A piece of trash drifts along with the flow of water through a pipe that is partially blocked. As the trash moves from the unblocked pipe into the partially blocked region its velocity A) stays the same. B) decreases. C) increases. D) An answer cannot be determin ed from the information given. 10) (2 pts) Consider the partially blocked pipe of the previous question. Which of the following is true? A) The water pressure is less in the partially blocked region compared to the unblocked region. B) The water pressure is greater in the partially blocked region compared to the unblocked region. C) The water pressure is the same everywhere in the pipe. D) An answer cannot be determined from the information given.

Explanation / Answer

option A is correct

pressure is less in partiallyy blocked region because according to bernoulli's

P + 0.5 rho *v^2 = P0 + 0.5 rho *v'^2

according to eqn of continuity

AV= A1v'

as we can see area at blocked region is less and hence velocity become more and as velocity increses K.E energy gets increases so Po will goes down.
