When you vomit your stomach forces a fluid flow from your mouth. Treating your stomach, esophagus, and mouth as a continuous ver

dalvyx [7]

Answer:

The gauge pressure as calculated is 5862.36 Pa

Solution:

As per the question:

Radius, r = 1 cm = 0.01 m

Length, l = 60 cm = 0.6 m

Velocity of discharge of fluid from the mouth, v = 1.5 m/s

Now,

By using the continuity equation:

Av = A'v' (1)

where

A = Area of the mouth

A' = Area of the tube

v' = Velocity of the fluid inside the stomach

Since, the question assumes the stomach, mouth and esophagus as continuous vertical tube, then:

A = A'

Thus

From eqn (1):

v = v' = 1.5 m/s

Now,

With the help of Bernoulli's equation:

$P + \frac{1}{2}\rho v^{2} + \rho gh = P' + \frac{1}{2}\rho v'^{2} + \rho gh'$

$P + \frac{1}{2}\rho v^{2} + \rho g(h - h') = P' + \frac{1}{2}\rho v^{2} +$

$\rho g(h - h') = P' - P$

where

h - h' = l = 60 am = 0.6 m

P = Pressure at mouth = 1 atm = $1\times 10^{5}\ Pa$

g = acceleration due to gravity

Density of water, $\rho = 997\ kg/m^{3}$

P' = Pressure inside the stomach

P' - P = Gauge Pressure

$P' - P = 997\times 9.8\times 0.6 = 5862.36\ Pa$

The integral with respect to time of a force applied to an object is a measure called impulse, and the impulse applied to an obj

aliina [53]

Answer:

Follows are the solution to this question:

Explanation:

By checking the value in which we have calculated by performing its differentiation of $\frac{a}{3}t^3+bt$ , the correct form of its integer value is calculating with regard to t, that also provides as expected $at^2+b = F(t)$ .

Resistance is seen as part of ______________--- how a person understands his or her being and relationship to the world at large

aleksley [76]

Answer:

The self and world construct

Explanation:

in physics

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

Self psychology views resistances as protecting a vulnerable self. Resistances are seen as efforts to maintain levels of organization that patients have achieved within the context of their traumatic life situation.

A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. after the collision, the first ball moves at 5.39

kodGreya [7K]

To do this question, we need to know that momentum is conserved, meaning the overall velocity of the two balls has to be the same before and after the collision. 

After collision... 

Ball 1: 4.33m/s *cos 30 = 3.75 m/s (x-component) 
4.33m/s * sin 30 = 2.165 m/s ( y-component) 

Ball 2 (struck ball): 5 m/s - 3.75m/s = 1.25 m/s (x-component) 
-2.165 m/s (y-component) note: it has to be in the opposite direction to conserve momentum 

tan-1(2.165/1.25) = 60 degrees 
Struck ball's velocity = sqrt(1.25^2 + 2.165^2) = 2.5 m/s at 60 degree with respect to the original line of motion. 

Hope you understand!
