Consider a 1.72-m-tall man standing vertically in water and completely submerged in a pool. Determine the difference between the

pressures acting at the head and at the toes of this man, in kPa. The pressure difference acting between the head and toes of the man is kPa.

Answer:

Pressure difference between head and toes = 16872.2 Pa

Explanation:

The pressure difference between the head and toes of the man will be equal to the water pressure exerted at his toes. This can be found as follows:

Water pressure = (density of water) * (gravity) * (height of water)

Density of water = 1000 kg/m^3

Gravity = 9.81 m/s^2

Height of water = height of man = 1.72 m

Water pressure = 1000 * 9.81 * 1.72

Water pressure = 16872.2 Pa

The neurons of giant squids, for example, consist of axons with very large radii, which allows the squid to react very quickly w
Alinara [238K]

Answer:

100

Explanation:

\rho_m = Resistivity of axon

r = Radius of axon

t = Thickness of the membrane

\rho_a = Resistivity of the axoplasm

Speed of pulse is given by

v=\sqrt{\dfrac{\rho_mrt}{2\rho_a}}

So, radius is given by

r=\dfrac{2\rho_a}{\rho_mt}v^2

If radius is increased by a factor of 10 new radius will be

r_2=\dfrac{2\rho_a}{\rho_mt}(10v)^2\\\Rightarrow r_2=100\dfrac{2\rho_a}{\rho_mt}v^2\\\Rightarrow r_2=100r

So, The radius will increase by a factor of 100.

Suppose a car is traveling in the negative x-direction and comes to a stop. What is the sign of that car’s acceleration? How do
Oduvanchick [21]

We have equation of motion v = u + at

Where v = final velocity, u = initial velocity, a = acceleration, and t = time

In this case car is travelling in -x direction

Velocity of car = displacement / time

Since displacement value is increasing in negative x axis it's initial velocity is negative

And it's final velocity is zero since it comes to rest, and time is also positive

So, v= u+ at => 0 = -u + at

   So, a = u/t

Which is positive and along positive X - direction

A) Using Excel, or some other graphing software, plot the values of y as a function of x. (You will not submit this spreadsheet.
tiny-mole [99]

Answer:

   y = 1.06 x + 0.14

            r² = 0.95

Explanation:

a) To make this graph, a spreadsheet-type calculation program is used, see attached.

On the y axis are the measured values

On the x-axis, the values ​​checked in the experiment are placed.

From the graph we see that a linear graph and that one of the values ​​has a strong deviation with respect to the others

b) The red line is the best straight line that can be drawn,

    for this the quality ajust is r²  

the closer to 1 the better the fit

           

the equation of the line is

            y = 1.06 x + 0.14

            r² = 0.95
