Answer:
a
b
Explanation:
From the question we are told that
The pressure of the water in the pipe is
The speed of the water is
The original area of the pipe is
The new area of the pipe is
Generally the continuity equation is mathematically represented as
Here is the new velocity
So
=>
=>
=>
=>
Generally given that the height of the original pipe and the narrower pipe are the same , then we will b making use of the Bernoulli's equation for constant height to calculate the pressure
This is mathematically represented as
Here is the density of water with value
=>
=>
i can't comment but do you have a pic of the work you need help with?
2.25 cubic meters of space is the same as 2.25 million cubic centimeters, no matter what's in it. Even if it's empty.
F = ma
1500 = 1500a
a = 1 m/s²
Answer:
1.52905 seconds
4.58715 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
= Coefficient of friction = 0.4
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration =
Equation of motion
It will take 1.52905 seconds for the block to slow down
The block will travel 4.58715 m before it stops
