Answer:
1 minute 36.85 seconds
Explanation:
First we need to convert the miles into meters, as the demanded result should be in meters.
1 mile = 1,609.34 meters
Also, 6.5 minutes should be converted into seconds.
1 minute = 60 seconds
6.5 x 60 = 390 seconds
Now we need to divide the miles with the seconds to see how much meters have been run in a second.
1,609.34 / 390 = 4.13 meters
The suggested meters now should be divided with the distance run in one second.
400 / 4.13 = 96.85 seconds
So we get a result of 96.85 seconds, or 1 minute 36.85 seconds.
Answer:
Explanation:
Given

Volume Flow rate 
Length 
radius 

According to Hagen-Poiseuille Equation
difference in Pressure is given






The tension in the first and second rope are; 147 Newton and 98 Newton respectively.
Given the data in the question
- Mass of first block;

- Mass of second block,

- Tension on first rope;

- Tension on second rope;
To find the Tension in each of the ropes, we make use of the equation from Newton's Second Laws of Motion:

Where F is the force, m is the mass of the object and a is the acceleration ( In this case the block is under gravity. Hence ''a" becomes acceleration due to gravity
)
For the First Rope
Total mass hanging on it; 
So Tension of the rope;

Therefore, the tension in the first rope is 147 Newton
For the Second Rope
Since only the block of mass 10kg is hang from the second, the tension in the second rope will be;

Therefore, the tension in the second rope is 98 Newton
