The formula that is applicable here is E = kQ/r^2 in which the energy of attraction is proportional to the charges and inversely proportional to the square of the distance. In this case,
kQ1/(r1)^2 = kQ2/(r2)^2 r1=l/3, r2=2l/3solve Q1/Q2
kQ1/(l/3)^2 = kQ2/(2l/3)^2 kQ1/(l^2/9) = kQ2/(4l^2/9)Q1/Q2 = 1/4
Answer
Total force exerted by brake cylinders is 249.69 N
Explanation:
We have given that force 
And area of the cylinders 
We have to find the total force
We have given total surface area 
From pascal's law we know that 
And we know that 
So 
Answer:
Force = 24.5 Newton
Explanation:
Given the following data;
Mass = 3.50 kg
Initial velocity, u = 3 m/s
Final velocity, v = 17 m/s
Time, t = 2 seconds
To find the force;
First of all, we would determine the acceleration of the object using the formula;
Acceleration = (v - u)/t
Acceleration = (17 - 3)/2
Acceleration = 14/2
Acceleration = 7 m/s²
Now, we can find the force using the formula;
Force = mass * acceleration
Force = 3.5 * 7
Force = 24.5 Newton
The theory is revised or updated. It may strengthen; however, cannot become a law. The "catch" with theories is that they may be disproven at any point in time by experimental results that contradict them. Therefore, they cannot become a law by just one additional supporting experiment.
I think you wanted to know whether the statement given is true or false. Based on this assumption, i am trying to answer the question as accurately as possible and hope that it helps. It is a true statement that amount consumed from each food group depends on their age, gender and physical activity of a person. A sportsman will consume a different amount from each food group than a normal person is a simple example.
