Answer:

1.29 N

Explanation:

The equation for force (with work and distance) is:

Force=\frac{Work}{distance}

We can plug in the given values into the equation:

Force=\frac{9J}{7m}$\approx1.29 N

Answer:

1.29 Newtons

Explanation:

The equation for this question would be work = force x distance so you substitute in the values. After doing this, you should divide 9 by 7 which gives you 1.29 (rounded to 2 d.p.)

A major artery with a cross sectional area of 1.00cm^2 branches into 18 smaller arteries, each with an average cross sectional a
dybincka [34]

Here we can say that rate of flow must be constant

so here we will have

A_1v_1 = 18 A_2v_2

now we know that

A_1 = 1 cm^2

A_2 = 0.4 cm^2

now from above equation

1 cm^2 v_1 = 18(0.400 cm^2)v_2

\frac{v_2}{v_1} = \frac{1}{18\times 0.4}

\frac{v_2}{v_1} = 0.14

so velocity will reduce by factor 0.14
