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
Answer:
energy
Explanation:
waves can move distances without transferring any matter, so the answer is energy
Answer:
The value is
Explanation:
From the we are told that
The radius of the sphere is
The temperature is
The average temperature of the rest of the universe is
Generally the change in entropy of the entire universe per second is mathematically represented as
Here is the entropy of the rest of the universe which is mathematically represented as
Here Q is the quantity of heat radiated by the star which is mathematically represented as
Here is the Stefan-Boltzmann constant with value
=>
=>
So
=>
Here is the entropy of the rest of the universe which is mathematically represented as
=>
=>
So
=>
It’s the gravity pull of the sun that makes them spin around 360 degrees
It’s all so why they say In a billion years the sun will smash into the sun
