Answer
given,
diameter of segment 1, d₁ = 1 cm
diameter of segment 2, d₂ = 2 cm
diameter of segment 3 , d₃ = 0.5 cm
speed of liquid in first segment, v₁ = 8 m/s
a) using continuity equation
A₁ v₁ = A₂ v₂
v₂ = 2 m/s
speed in the second segment = 2 m/s
b) again, using continuity equation
A₂ v₂ = A₃ v₃
v₂ = 32 m/s
speed in the second segment = 32 m/s
c) Flow rate in the pipe
Q = A₁ V₁
Q = 6.28 x 10⁻⁴ m³/s
Q = 62.8 L/s
discharge in the pipe is equal to 62.8 L/s
In electrical work, silver is used as a conductor.
Explanation:
It is given that,
The acceleration of the toboggan,
Initial speed of the toboggan, u = 0
We need to find the distance covered by the toboggan. Using the second equation of motion as :
At t = 1 s
At t = 2 s
At t = 3 s
Hence, this is the required solution.
Answer:
(a) Current will be
(b) Number of ions will be
Explanation:
We have given that resistance of the biological cell
(a) We have given potential difference of 75 mV
So
From ohm's law we know that current is given by
(b) We have given time t = 0.74 sec
We have to find the charge
We know that charge is given by Q = it, here i is current and t is time
So charge will be
So number of ions will be
