Answer:
Time= 6.12*10^4s
mass flow rate m=0.98kg/s
Explanation:
Given
Volume= 60m^3
diamter= 2.5cm= 0.025m
radius= 0.0125m
area A= πr^2
area A= 3.142*0.0125^2
area A= 4.9*10^-4m^2
the velocity of the flow 2m/s
<u>volume flow rate </u>
V=vA
V=2* 4.9*10^-4
V=9.82*10^-4 m^3/s
<u>Time taken to fill the pool</u>
time= volume/volume flow rate
time= 60/9.82*10^-4
time= 6.12*10^4s
<u>Mass flow rate </u>
m= density *volume flow rate
Assuming the density of water to be 997kg/m^3
m= 997*9.82*10^-4
m=0.98kg/s
Answer:
A. Their shape
Explanation:
The name clearly shows that the shape of these canals are semi-circular. The semi-circular canals consist of three tubes filled with fluid and located in the inner ear. They help to maintain balance and transmit impulses through the movement of the fluids. The impulses sent through these fluids are sent to the brain for interpretation.
The function of the canals are not indicated by the name, rather the shape is hinted through the name.
Answer:
Sink
Explanation:
The normal density of water is 1 g/cm3. Since the rock has a higher density of 1.72g/cm3, it will sink in water.
They attract if they are oppositely charged and they repel if they have the same charges.
Answer:
Resultant velocity will be equal to 6.10 m/sec
Explanation:
We have given a motorbike is traveling with 5 m/sec in east
And a current is flowing at a rate of 3.5 m /sec in north
We know that east and north is perpendicular to each other
So resultant velocity will be vector sum of both velocity
So resultant velocity 
So resultant velocity will be equal to 6.10 m/sec
