by a seprating funnel or let it stand it will settle on its own
Explanation:
The answer is true. It tells me I have to have 20 characters.
Answer:
1,373.4 N
Explanation:
The mass of the table acts at the centre in addition to the books since that is the centre of gravity of the table.
Mass of books will be 10kg+20kg+30kg=60 kg
Total mass of table and books will be 500kg+60kg=560 kg
This mass is evenly distributed into the four legs hence 560kg/4 legs=140 kg per leg
Force is product of mass and acceleration due to gravity hence F=gm
Taking g as 9.81 m/s2 then
F=140*9.81=1,373.4 N
Therefore, rhe normal force is equivalent to 1,373.4 N
Answer:
1.40 m/s^2
Explanation:
Given data
Velocity= 17.4 m/s
time= 12.4 seconds
We want to find the acceleration of the rock
We know that
acceleration = velocity/time
Substitute
acceleration= 17.4/12.4
acceleration=1.40 m/s^2
Hence the acceleration is 1.40 m/s^2
Answer:
The pressure at point 2 is 
Explanation:
From the question we are told that
The speed at point 1 is 
The gauge pressure at point 1 is 
The density of water is 
Let the height at point 1 be
then the height at point two will be

Let the diameter at point 1 be
then the diameter at point two will be

Now the continuity equation is mathematically represented as

Here
are the area at point 1 and 2
Now given that the are is directly proportional to the square of the diameter [i.e
]
which can represent as

=> 
where c is a constant
so 
=> 
=> 
Now from the continuity equation
=>
=>

Generally the Bernoulli equation is mathematically represented as

So
=> 
substituting values
