The real world examples that I can give is the everyday
things that we do and some of these are:
I am walking to the end of the room holding three textbooks.
Playing tug of war with friends.
Getting the groceries from the car and put it inside of your house.
Answer:
0.14
Explanation:
Flow rate is the volume flowing through a point at a particular time, in calcuing flow rate we have
Q= v*t
it in terms of Area, we have Q= A*v
Where A= area
v= velocity.
Solving the question , flow rate is constant then
A*v= constant
A(i) v(i)= A(f) v(f)
Where A(i)= initial area= 1.00cm^2
A(f)= final area= 0.400cm^2
V(i) and V(f) are the initial and final velocity respectively and the ratio of the two will gives us the factor
Substitute the values into the equation we have
1 V(i)= 4 V(f)
But we were told that the cross sectional area of 1.00cm^2 branches into 18 smaller arteries.
Then
1 V(i)=0.4 V(f)*(18)
1 V(i)=7.2V(f)
Then if we find the ratio of the velocity, we will get the factor.
V(f)/V(i)= 1/7.2
V(f)/V(i)=0.14
Hence, the factor of the average velocity of the blood reduced when it passes into these branches is 0.14
Answer:
(a) 1/60
(b) Yes, it was unusual.
Explanation:
Number that went to the right field = 19
Number that went to the right center field = 18
Number that went to the center field = 12
Number that went to the left center field = 10
Number that went to the left field = 1
Total number of home runs = 60
(a) The probability that a randomly selected home run was hit to left field is
P(left field) = 1/60
(b) It was unusual because whenever a player hit a home run, it most times went to the right field,which is why the right field had the highest probability, 19/60.
On the other hand, it went to the left field the least number of times, which is why the left field had the least probability, 1/60.
So, it was unusual.
Answer:
The handels are plastic because plastic is not a conductor of heat. This way, the plastic prevents u from getting burnt/hurt.
Explanation:

i honestly don't even know but yahoo answers says :
Impulse causes momentum to change, which means:
Impulse = change in momentum, or in equation form:
F∆t = (mv)2 – (mv)1
so p (impulse)= mass times velocity so the mass is 2,000kg and the velocity is 12,000N/5s.
speed is basically velocity so you have to calculate how many newtons per one second, so 12,000/5s-- just divide the numerator and denominator by 5. Also, velocity and speed are measured in N/s.
