there is an inverse relationship between energy of light and wavelength group of answer choices true false

Answers

Answer 1

False Relationship between energy  to wavelength is also inverse as wavelength to frequency. As wavelength gets shorter ,the energy will increases and vice versa.

Energy can also be linked to light, and there is a clear relationship between energy and wavelength. The energy decreases as the wavelength lengthens and vice versa. Visible light has a lower energy than, for example, X-rays or ultraviolet light and a higher energy than infrared radiation or radio waves. The wavelength has an inverse relationship with the amount of energy because the electromagnetic frequency of the photon is directly proportional to it. The frequency of a photon determines its energy. The energy of a photon decreases proportionally to its wavelength. Longer wavelengths and lower frequencies correspond to warmer colors. Shorter wavelengths and higher frequencies correspond to cooler colors. The Greek letter lambda λ, which represents wavelength, is frequently used.

relate to current, real-world advances in windmill technology. Describe the
problems with windmill technology and how engineers have solved them.
Provide specific real-world examples of where new windmill technology is
being used.

Answers

Answer:

windmill, device for tapping the energy of the wind by means of sails mounted on a rotating shaft. The sails are mounted at an angle or are given a slight twist so that the force of wind against them is divided into two components, one of which, in the plane of the sails, imparts rotation.

Explanation:

The use of windmills was increasingly widespread in Europe from the 12th century until the early 19th century. Their slow decline, because of the development of steam power, lasted for a further 100 years. Their rapid demise began following World War I with the development of the internal-combustion engine and the spread of electric power; from that time on, however, electrical generation by wind power has served as the subject of more and more experiments

To work efficiently, the sails of a windmill must face squarely into the wind, and in the early mills the turning of the post-mill body, or the tower-mill cap, was done by hand by means of a long tailpole stretching down to the ground. In 1745 Edmund Lee in England invented the automatic fantail. This consists of a set of five to eight smaller vanes mounted on the tailpole or the ladder of a post mill at right angles to the sails and connected by gearing to wheels running on a track around the mill

The most important use of the windmill was for grinding grain. In certain areas its uses in land drainage and water pumping were equally important. The windmill has been used as a source of electrical power since P. La Cour’s mill, built in Denmark in 1890 with patent sails and twin fantails on a steel tower. Interest in the use of windmills for the generation of electric power, on both single-user and commercial scales, revived in the 1970s.

Answers

The final velocity at the end of this time will be 200 [tex]m/s^{2}[/tex]

When any object is in free fall, then

The value of acceleration = g  [tex]m/s^{2}[/tex] = 10 [tex]m/s^{2}[/tex]

The initial velocity (u) = 0 m/s

Let the final velocity (v) = v m/s

The mass of the object (m) = 10 kg

Time taken to reach the ground = 20 s

We will calculate the height (s) from which the object falls,

We employ the 2nd equation of motion since the object is under constant acceleration,

We have,

Putting the values in the equation, we get

[tex]s = 0 +\frac{1}{2} *10 *20^{2} \\\\s = 2000[/tex]

Putting all the values, we get,

[tex]v^{2} -0^{2} = 2*10*2000\\\\v^{2} = 40000\\\\v = 200[/tex]

Part C Compute the vertical height through which the pendulum rises. Express your answer in centimeters.

Answers

A) The initial kinetic energy of the bullet is 722J

B) Kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum  0.68J

C)  The vertical height through which the pendulum rises  0.69cm

The following data-

Mass of the bullet - 10.0g

speed - 380m/s

mass of the pendulum - 10.0kg

length of cord - 70.0cm

To find the initial kinetic energy of the bullet -

KE=1/2mv^2

KE = 1/2 x 0.010 x 380^2

KE= 722J

initial kinetic energy = 722 J

To find the Kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum, we need to first find the final velocity and vertical height through which pendulum rises-

we will find final velocity by applying the law of conservation of momentum

We know, Momentum of bullet is equal to the sum of the momentum of bullet and pendulum.

MbVb= (Mb+Mp)V

where,

Mb= mass of bullet

Mp = mass of pendulum

Vb = velocity of bullet

V = Final velocity

0.010 x 380 = ( 0.010 + 10)V

3.8 = 10.01V

V = 3.8/10.01

v = 0.37m/s

The final velocity = 0.37m/s

now, to find the vertical height

height = V^2/2g

= 0.37^2/2 x 9.8

= 0.136/19.6

= 0.00693m

converting to cm

0.00693 x 100 = 0.69 cm

To find the kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum -

KE = 1/2 (Mb + Mp)V^2

KE = 1/2 ( 0.010 + 10) x 0.37 ^2

when a thick lamp filament and a thin lamp filament are connected in parallel, which has the greater voltage drop?

Answers

A thick filament will draw more current than a tiny wire linked across the same potential difference because it has lower resistance.

The voltage drop across each bulb is 6.0 V when the light bulbs are linked in parallel, and they all glow as the current passing through them combines to generate the current flowing through the battery. It is accurate to say that a battery experiences more electrical resistance than the resistance when two bulbs are linked in series.

A filament lamp's resistance rises as the potential difference widens because the filament gets hotter. The current is produced by the flow of electrons, which also causes the atoms inside the filament to vibrate more rapidly, which causes the filament to heat up.

Answers

Answer: 35 m/s

Explanation: Gravitational acceleration only affects the vertical component of motion meaning the horizontal component never changes. This means 35 m/s is the correct answer.

A projectile is fired horizontally at an initial horizontal speed of 35 meters per second from a height of 65 meters, after falling 25 meters, the projectile's horizontal speed is 35 m/s.

What is speed?

 

The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar number.

Speed is calculated using the formula s=d/t, where s is the speed in m.s⁻¹, d is the distance in m, and t is the time in s.

Variable speed is when an object travels a different distance at the same time intervals, whereas uniform speed is when an item travels the same distance at the same time intervals.

Time period : The satellite period is the time it takes for a satellite to make one orbit around the Earth, denoted by T. Therefore, T = distance traveled in 1 revolution/orbital velocity = 2πr/V.

We have the following information,

the Satellite revolves the earth twice in a day .

As we know,

mass of the earth(M) is 5.97 × 1024 kg

Gravitational constant (G)= 6.67 × 10-11 Nm²/kg²

The time taken to complete two rounds is a day. Time taken by the satellite in one alone will be cost to one by the day i.e., T = 24 hours

The time period of the satellite must be equal to

2T = 2×24×60×60 sec = 172800 sec.

According to Kepler's 3Rd law ,

T² = ( 4π²/GM )r³---(1)

where, T ---> time period

M --> mass of earth

G--> gravtional constant

r --> radius of orbit

putting all the values in above formula

(172800)² = ( 4×(3.14)²/(6.67 × 10-11 Nm²/kg²× 5.97 × 1024 kg))r³

The angle at which a ray of light strikes a pane of window glass is smaller than the angle at which it passes out the other side.

When light go through window glass it will experience refraction due to change of light speed. The relation between angle of incidence and angle of refraction is given by the Snell's law:

n₁ sin∅₁ =  n₂ sin∅₂

Where:

n₁ = incident index (refractive index of medium 1)

n₂ = refraction index ((refractive index of medium 2)

∅₁ = incident angle

∅₂ = refraction angle

Typical refractive index for glass is around 1.5 while refractive index for air is 1.000273.

an object is placed in a fluid and then released. assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom. (note that for parts a through d, you should assume that the object has settled in equilibrium.)

Answers

The correct Option is Always true.

According to Archimedes' principle when an object is immersed in a liquid, and it is either partially or wholly submerged, the upward force that acts on the object, is known as buoyancy force and it is equal to the weight of the liquid displaced by the object.

So, the buoyancy force is always present whenever an object is placed in a liquid. Archimedes' principle proves that The magnitude of buoyancy force is always equal to the weight of the fluid  displaced by the object

Hence the correct option is Always.

Answers

The cube will float.

What is Archimedes' principle?

The upward buoyant force that is applied to a body submerged in a fluid, whether wholly or partially, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid, according to Archimedes' principle.

Given parameters:

The average density of an object is 0.46 kg/m³.

The density of olive is oil 0.92 kg/m³.

As The average density of an object  < density of olive oil; the liquid displaced by the object has more weight than the weight of the object.

Dollar amounts are displayed as integers with comma separators. Ex: System.out.printf("Cost: $%,d\n", cost); Note: this program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. Step 1. Within main() input wages, taxable interest, unemployment compensation, status (0=dependent, 1=single, and 2=married), and taxes withheld as integers. Step 2 (2 pts). Complete the calcAGI() method. Calculate the adjusted gross income (AGI) that is the sum of wages, interest, and unemployment. Convert any negative values to positive before summing to correct potential input errors. Return the AGI. Note the provided code in main() calls calcAGI() and outputs the returned value. Submit for grading to confirm two tests pass. Ex: If the input is:20000 23 500 1 400The output is:AGI: $20,523Step 3 (2 pts). Complete the getDeduction() method. Return the deduction amount based on status: (0) dependent = 6000, (1) single = 12000, or (2) married=24000. Return 6000 if the status is anything but 0, 1, or 2. Within main() call getDeduction() and output the returned value. Submit for grading to confirm four tests pass.
