Answer:
Explanation:
The volume flow rate of a fluid in a pipe is given by:
where
A is the cross-sectional area of the pipe
v is the speed of the fluid
In this problem, at the initial point we have
v = 0.84 m/s is the speed of the water
r = 0.21 m is the radius of the pipe, so the cross-sectional area is
So, the volume flow rate is
Answer:
Lacks colored blood - Scorpion
Soft, unsegmented body - Octopus
A vertebrate - Bird
Lacks antennae - Starfish

Answer:
Explanation:
Speed of an object is defined as the ratio of the distance covered by the object to the time taken to cover that distance.
Let 
be the speed of the object.
Let 
be the distance travelled by the object.
Let 
be the time taken by the object.
So,
s=
So,the speed of the car is
