A brewpub is brewing beer in a large cylindrical container with radius 6 meters. Beer is being removed from the container at a r

ate of 15 cubic meters per hour. Find the rate at which the height of beer in the container is changing. The volume of a cylinder is given by Upper V equals pi r squared h​, where r is the radius and h is the height of the cylinder.

Answer:

\frac{dh}{dt} = \frac{F_{in} }{36\pi } - \frac{5}{12}

Explanation:

Thinking process:

Let the radius = 6 m

The rate of removal of the beer = 15 m³/hr

This can be written as: F_{out}  = 15 m^{3}/hr

the rate or change \frac{dV}{dt} = F_{in} - F_{out}

this changes to \frac{d(Ah)}{dt} = F_{in} - F_{out}   \\A\frac{dh}{dt}= F_{in}-F_{out}   \\\frac{dh}{dt } = \frac{1}{A}(F_{in}-F_{out})\\    =\frac{F_{in} }{36}-\frac{5}{12}

The gyri and sulci on the brain greatly increase the brain’s surface area. How do you think this increase in surface area relate
MrRa [10]

Answer:

Increase in surface area leads to more chances for connections between neurons hence more possible learning

Explanation:

The brain appears wrinkled due to the presence of gyri and sulci. Sulci are the grooves in the brain while gyri are the folds. The two major functions of gyri and sulci are to lead to formation of brain divisions and increase the surface area of cerebral cortex. The formation of brain divisions is done by creating boundaries between the brain lobes thereby leading to division of the brain into two hemispheres. Moreover, by increasing the surface area of the brain, the cortex processes more information since more neurons are formed.

If you need 40.0 Nm of torque in order to loosen a nut on a wn
KonstantinChe [14]

Answer:

0.301 m

Explanation:

Torque = Force × Radius

τ = Fr

40.0 Nm = 133 N × r

r = 0.301 m

The mechanic must apply the force 0.301 m from the nut.

The laboratory exercise for this chapter addresses kinematic motion. You have experienced these motions in everyday life. Instea
ki77a [65]

Answer:

A) vectors: veloicty, force

scalar:  speed, work

B)  t = 1.75 s,  C)   v = - 17 2 m / s

Explanation:

We answer each part separately

A) A vector magnitude has magnitude and direction instead a scalar magnitude has only magnitude

vector quantities: the speed of a car number is the magnitude and direction is where it goes

Force, the number is the magnitude and above that applies gives direction

Scalar magnitude: how quickly the number of the speedometer of the car

Temperature, work

B) I = 15 m height to the soil and get to calculate time = 0

        y = y₀ + v₀ t - ½ g t²

as the ball is loose its initial velocity is zero

       0 = 0 +0  - ½ g t²

       t = \sqrt{2y_o/g}

       t = \sqrt{2 \ 15/ 9.8}

       t = 1.75 s

C) the velocity to the reach the floor

      v = vo - g t

      v = 0 - g t

      v = - 9.8 1.74

       v = - 17 2 m / s

The negative signt iindicates that the speed goes down

The tendency of all objects to continue with your previous motion when the net force acting on the object is zero is known as?
Bingel [31]

Answer:

Inertia

Explanation:

The state of motion of an object is defined by its velocity the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity - and ( in the absence of an unbalanced force ) will remain with a zero velocity.
