a cylindrical container with a cross-sectional area of 64.2 cm2 holds a fluid of density 776 kg/m3. at the bottom of the container the pressure is 121 kpa. assume Pat = 101 kPa. What is the depth of the fluid, in meters?

Answers

Answer 1

If a cylindrical container with a cross-sectional area of 64.2 cm2 holds a fluid of density 776 kg/m3 The depth of the fluid in the cylindrical container is 2.56 meters.

We can use the hydrostatic equation to find the depth of the fluid in the cylindrical container:

ΔP = ρgh

where:

ΔP = difference in pressure (Pa)

ρ = density of fluid (kg/m3)

g = acceleration due to gravity (9.81 m/s2)

h = height or depth of fluid (m)

First, let's convert the cross-sectional area from cm2 to m2:

64.2 cm2 = 0.00642 m2

Next, let's find the difference in pressure:

ΔP = 121 kPa - 101 kPa = 20 kPa = 20,000 Pa

Now, let's plug in the values we have into the hydrostatic equation and solve for h:

ΔP = ρgh

20,000 Pa = (776 kg/m3)(9.81 m/s2)h

h = 2.56 meters

Therefore, the depth of the fluid in the cylindrical container is 2.56 meters.

A military surveillance satellite is in circular orbit around the Earth at an altitude of 1,000 km above the surface. If the Earth's mass is 5.97 x 1024 kg and its radius is 6,370 km, what is the satellite's orbital speed in m/s

Answers

The orbital speed of the satellite is 7.35*10^3 m/s.

What is orbital speed?

The speed of the satellite in its orbit is termed the orbital speed.

The orbital speed is given by the formula,

[tex]v=\sqrt{\frac{GM}{r}}[/tex]

where G is the universal gravitational constant, M is the mass of the planet and r is the distance of the satellite from the center of the planet.

Here the distance of the satellite from the center of the planet is the sum of the planet's radius and the height attained by the satellite above the ground. So

r=6370 + 1000

r=7370 km

Given the mass of the planet is 5.97*10^24 kg and the value of the gravitational constant is 6.67*10^(-11) N m^2 kg^(-2), substitute these values in the formula of the orbital speed.

Note: 1 km=1000 m

[tex]v=\sqrt{\frac{6.67\times10^{-11}\text{ N m}^2\text{kg}^{-2}\times5.97\times10^{24} \text{ kg}}{7370 \text{ km}}} \\ v=\sqrt{\frac{6.67\times10^{-11}\text{ N m}^2\text{kg}^{-2}\times5.97\times10^{24} \text{ kg}}{7370\times 1000 \text{ m}}} \\ v= 7.35\times 10^3 \text{ m/s}[/tex]

. A coil is wrapped with 400 turns of wire on the perimeter of a circular frame of radius 8.5cm. Each turn has the same area, equal to that of the frame. A uniform magnetic field is turned on perpendicular to the plane of the coil. This field changes at a constant rate from 10.0 to 80.0mT in a time of 20.0ms. What is the magnitude of the induced emf in the coil at the instant the magnetic field has a magnitude of 50.0mT

Answers

The emf in the coil when the magnetic field is 50.0 mT is 31.78 V.

What is emf?

According to Faraday's law of electromagnetism, the emf of a coil  

is the negative of the rate of change of magnetic flux with respect to time.

The emf of a coil is given by the formula,

[tex]E=-\frac{d\phi}{dt}[/tex]

where E is the emf, dΦ is the change in flux and dt is the change in time.

Magnetic flux: The scalar product of the magnetic field B and the total area vector A perpendicular to it is called the magnetic flux. The magnetic flux for a circular coil with n number of turns is given by,

[tex]\phi=n\pi r^2B[/tex]

where r is the radius of the coil.

Substitute [tex]\phi=n\pi r^2B[/tex] in the above equation and solve it.

[tex]E=-\frac{d(n\pi r^2 B)}{dt}\\E=-n\pi r^2 \frac{dB}{dt}[/tex]

Where dB/dt is the rate of change in the magnetic field with respect to time.

Note: 1mT/ms= 1 T/s, 1 cm= 0.01 m and 1mT=0.001 T

Given the magnetic field changes from 10.0mT to 80.0mT, the change in magnetic field dB = 80-10=70mT. The time interval dt= 20.0ms. Therefore,

dB/dt = 70/ 20 =3.5mT/(ms)

dB/dt = 3.5 T/s

Substitute dB/dt= 3.5T/s,  n=400, r=8.5 cm or r=0.085 m in the formula of E and solve it. Since the value of magnitude is positive, ignore the negative sign.

E=400*π*(0.085)^2*(3.5)

E=31.78 V

Since the rate of change of magnetic field is constant, so the magnitude of the emf of the coil will remain the same at all instants. Hence E=31.75 V when the magnitude of the magnetic field is 50.0 T

In a given neuron, the current membrane potential is 60 mv. what does this tell you about the current potential compared to the resting membrane potential of 70 mv?

Answers

The membrane is depolarized compared to the resting membrane potential.

Through conformational changes from closed, nonconducting states to an open, current-conducting state, membrane depolarization activates sodium channels. Na+ channels open slowly and change from an open state to a nonconducting, rapidly inactivated state as a result of delayed openings, which contribute to the declining fraction of INa induced by prolonged depolarization. Additionally, sodium channels can move swiftly from the closed state to the fast-inactivated state. When the membrane is depolarized, inactivated channels are prevented from opening.

The distribution of channels between the closed and slow-inactivated states, however, limits the number of excitable sodium channels as a function of the membrane potential since slow inactivation acts at greater negative potentials than fast inactivation.

A 1500 pound car is stopped in traffic on a hill that is at an incline of 10. Determine the force that is required to keep the car from rolling down the hill.

Answers

A 1500 pound car is stopped in traffic on a hill that is at an incline of 10. The force that is required to keep the car from rolling down the hill will be 1133.53 N.

When all the forces that act upon an object are balanced, then the object is said to be in equilibrium motion. The forces are considered to be balanced if the rightward forces are balanced by the leftward forces and the upward forces are balanced by the downward forces.

It can be observed from the diagram that in order resist the car to rolling down the hill we need to apply an equal and opposite force against the inclined force( that is mgsin(x)) to form an equilibrium position because rolling is associated with horizontal forces hence we need to apply force against the force which can drive down the car .

mass = 1500 pound = 680.39 kg

sin(10) = 0.17

F (counter force ) = m*g*sin(x)

                             = 680.39  * 9.8 * 0.17

A. What can happen to energy in a system is that it can be converted.

What is the principle of conservation of energy?

The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.

The energy of a system can be converted from one form to another.

Thus, what can happen to energy in a system is that it can be converted.

If a car increases its velocity from +6 m/s to +30 m/s in 6 seconds, its acceleration in m/s2 is__________.

Answers

Answer:

4m/s^2

Explanation:

v = 30m/s, u = 6m/s, t = 6s

Change in velocity = v(final velocity) - u (initial velocity)

v-u = 30-6 = 24m/s

acceleration = (v-u)/t

(24m/s)/6s = 4m/s^2

A 540 gram object is attached to a vertical spring, causing the spring’s length to change from 70 cm to 110 cm.

What is the change in the object’s gravitational potential energy?

Group of answer choices

-2.1 J

-0.84 J

2.1 J

0.84 J

Answers

The change in the object’s gravitational potential energy is 2.11 J.

Change in the object's gravitational potential

ΔP.E = mg(hf - hi)

where;

m is mass of the objecthf is final height hi is initial height

ΔP.E = 0.54 x 9.8(1.1 - 0.7)

ΔP.E = 2.11 J

Thus, the change in the object’s gravitational potential energy is 2.11 J.

____________ is the unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.

Answers

Volt is the unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.

When there is a circuit having a cell / battery , that cell/battery forms an electric field due to difference in voltages , and set a voltage of value equals to the difference in the voltage of two end of that cell/ battery . Because of which a electric field got set up in the conductor , which pushes electron to move inside the conductor . Unit of voltage is volt .

VOLT - A unit of electrical pressure (or electromotive force) which causes current to flow in a circuit. One volt is the amount of pressure required to cause one ampere of current to flow against one ohm of resistance. VOLTAGE - That force which is generated to cause current to flow in an electrical circuit.

Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).
