An object appears red when viewed with white light. What color would it appear when viewed with blue light?

i searched this in googl.e, and there was one website, so i clicked it, and umm it was very disgusting ,,,

For this assignment, you will develop several models that show how light waves and mechanical waves are reflected, absorbed, or transmitted through various materials. For each model, you will write a brief description of the interaction between the wave and the material. You will also compose two typewritten paragraphs. The first will compare and contrast light waves interacting with different materials. The second will explain why materials with certain properties are well suited for particular functions.

A wave is any disturbance that carries energy from one place to another. There are two different types of waves: mechanical and electromagnetic. A mechanical wave carries energy through matter. Energy is transferred through vibrating particles of matter. Examples of mechanical waves include ocean waves, sound waves, and seismic waves. Like a mechanical wave, an electromagnetic wave can also carry energy through matter. However, unlike a mechanical wave, an electromagnetic wave does not need particles of matter to carry energy. Examples of electromagnetic waves include microwaves, visible light, X-rays, and radiation from the Sun.

Answer:

Explanation:

First of all, I used the specific heat of water as 4182 J/(kgC) and the specific heat of ethyl alcohol (EtOH) as 2440 J/(kgC); that means that we need the masses in kg, not g.

120.g = .1200 kg of ethyl alcohol. Now for the formula:

[tex]t_f=\frac{(m_{H2O}*spheat_{H2O}*temp_{H2O})+(m_{EtOH}*spheat_{EtOH}*temp_{EtOH})}{(m_{H2O}*spheat_{H2O})+(m_{EtOH}*spheat_{EtOH})}[/tex] where spheat is specific heat.

Filling that horrifying-looking formula in with some values:

[tex]16.0=\frac{(x*4182*20.0)+(.1200*2440*10.0)}{(x*4182)+(.1200*2440)}[/tex] and

[tex]16.0=\frac{83640x+2928}{4182x+292.8}[/tex] and

16(4182x + 292.8) = 83640x + 2928 and

66912x + 4684.8 = 83640x + 2928 and

1756.8 = 16728x so

x = .105 kg and the amount of water added is 105 g

Molecules are the smallest fundamental units of a chemical compound that retain the chemical properties of that compound. They are composed of two or more atoms that are bonded together through chemical bonds.

Here,
Air is a mixture of gases, with the two most abundant elements being nitrogen (N2) and oxygen (O2), together making up about 99% of dry air.

Here are the chemical formulas of some of the other important gases in air,

Carbon dioxide (CO2)

Argon (Ar)

Neon (Ne)

Helium (He)

Methane (CH4)

Hydrogen (H2)

EMF induced in coil is directly proportional to the rate of change of magnetic flux by the flowing current with n number of turns in it.The total emf generated is 1.62 volts

Given-

Total coils in a solenoid [tex]N[/tex] is 365 coils.

The change in flux is,

[tex]d\phi=9.44\times10^{-5} -2.57\times 10^{-5}[/tex]

[tex]d\phi=6.87\times10^{-5}[/tex]

The change in time [tex]dt[/tex] is 0.0154 sec.

According to Faraday's law the EMF induced in coil is directly proportional to the rate of change of magnetic flux produced in the coil by the current i flowing in it with conductor having a finite number of turns in it.This can be given as,

[tex]emf=-N\dfrac{d\phi }{dt}[/tex]

[tex]emf=-364\times \dfrac{6.87\times 10^{-5}}{0.0154}[/tex]

[tex]emf= -1.62[/tex]

Explanation:

If the lens of our eyes were concave, we would not be able to see. We would be blind. This is because our eyes form a visual image on the same side of the lens at the object being viewed. Thus, a concave lens would result in the visual image focusing in front of the eye, not the retina inside the eye. This would mean that no signals would be sent to the brain, and vision would not be possible.

Answer:

6 kilograms

Explanation:

force (N) = mass (kg) × acceleration (m/s²).  an object of constant mass accelerates in proportion to the force applied. If the same force is applied to two objects of different mass, the heavier object has less acceleration than the lighter object. Divide the newtons by the rate of acceleration, which will give you the mass of the object. The mass will be in kilograms, because a single newton represents the amount of force needed to move one kilogram one meter.

The horizontal component of velocity is

(22 m/s) • cosine(62°).

The vertical component of velocity is

(22 m/s) • sine(62°).

These are the original components, right after the kick. As time goes on, the horizontal one doesn't change. But the vertical one gets bigger and bigger, because gravity is accelerating the ball downward.

That's the complete story of projectile motion.

Answer: Its B. There will be 0.031 kg left after 151 years,

Explanation: Im doing my assessment right now.

The half-life of Cs-137 is 30.2 years. If the initial mass of the sample is 1.00 kg, the mass remain after 151 years is 0.031 Kg.

Caesium-137, or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes.

Cs-137 is used in medical radiation therapy devices for treating cancer.

The half-life is the amount of time it takes for a given sample to lose half of the original amount or the time for radioactive substance to decay. The half-life of Cs-137 is 30.2 years.

Decay constant of radioactive substance is its probability of decay per unit time.

In this case,

Mass of sample is 1 Kg

Half-life of Cs-137 is 30.2 years

The elapsed time is 30.2 years.

This means, one half-life is elapsed, the half of sample will decay in 30.2 years. Therefore, the half of the original substance will remain in 30.2 years which is 0.500 Kg. After another 30.2 years, it will be 0.250 Kg. And after 151 years, it will be 0.031 Kg.

Las células del interior son negativas, mientras que en el exterior son positivas.

Explanation:

Que tenga un buen día :)

The time taken is 10 years.

The term simple interest is an interest that is charged only on the principal and not on the interest.

We have the following;

Principal =  500 birr

amount = 900 birr

rate = 8%

Interest = 900 birr - 500 birr = 400 birr

400 = 500 × 8 × T/100

400 × 100 = 500 × 8 × T

T = 400 × 100/500 × 8

T = 10 years

Answer:

10 years

Explanation:

To solve this first we have to find the simple interest.

Let us find it now.

Interest = birr 900 - birr 500

             = birr 400

Now we are having,

Amount = birr 900

Principal = birr 500

Interest = birr 400

rate = 8%

Period of time = ?

Let us use the formula to find the period of time.

Simple interest = Principal × Rate × Time ÷ 100

birr 400  = birr 500 × 8 × t ÷ 100

birr 400 × 100 = 4000t

40000 = 4000t

Divide both sides by 4000.

10 = t

Therefore, the time is 10 years.

Volume displaced by ducky = 75 mL = 7.5 x 10⁻⁵ m³

Mass displaced by the ducky = 7.5 x 10⁻² kg = 75 grams

Explanation:

The ducky will displace the volume of the water equal to its own volume.

Volume displaced by ducky = 75 mL = 7.5 x 10⁻⁵ m³

And the mass displaced by ducky will be equal to:

Mass displaced by the ducky = (Density of Water)(Volume displaced by ducky)

Mass displaced by the ducky = (1000 kg/m³)(7.5 x 10⁻⁵ m³)

Mass displaced by the ducky = 7.5 x 10⁻² kg = 75 grams

Answer:

The bullet that is fired will spend longer  in the air, hitting the ground after the  dropped bullet.

Explanation:

Using the equation: x =  x 0  +   v t

If we neglect the effects of air resistance, the horizontal motion is a constant velocity.

The horizontal displacement = (velocity X cosθ)

So, the fired bullet has to travel horizontally before falling which takes a  longer time compared to a bullet dropped where it is, height = 1/2 gt^2

gravity, g = 9.8 m/s2.

The time spent in air for the bullet projected at angle depends on the initial velocity of the bullet and angle of projection while bullet dropped from the same height depends on the final velocity of the bullet which depends on the height from the which the bullet was

The given parameters;

The time taken for the bullet fired at angle to return to the ground level is calculated as;

[tex]T = \frac{2 \times usin(30)}{g} \\\\T = \frac{u}{g}[/tex]

where;

The time taken for bullet dropped from the same height to reach the ground is calculated as;

[tex]v_f = v_0 + gt\\\\t = \frac{v_f - v_0}{g} \\\\t = \frac{v_f}{g}[/tex]

where

Thus, we can conclude that the time spent in air for the bullet projected at angle depends on the initial velocity of the bullet and angle of projection while bullet dropped from the same height depends on the final velocity of the bullet which depends on the height from the which the bullet was dropped.
