One light beam has wavelength, λ1, and frequency, f1. Another light beam has wavelength, λ2, andfrequency, f2. Write a proportion that shows how the ratio of the wavelengths of these two light beams is
related to the ratio of their frequencies.

Answers

Answer 1

Answer:

One light beam has wavelength, λ1, and frequency, f1. Another light beam has wavelength, λ2, and frequency, f2. Write a proportion that shows how the ratio of the wavelengths of these two light beams is related to the ratio of their frequencies as λ1/ λ2 = f1/ f2.

What is frequency?

The number of vibrations counted per second is called frequency. A wave is a group of vibrations that are referred to as energy. The bottom node is known as the crest, and the top node is known as the trough.

A proportion that shows how the ratio of the wavelengths of these two light beams is related to the ratio of their frequencies as λ1/ λ2 = f1/ f2.

Animation skills include all of the following, except which?a. layering
c. drawing
b. sketching
d. acting

Answers

Animation skills include all of the following except D. acting. Acting has nothing to do with your skills as an animator, whereas you do have to know how to do layering, drawing, and sketching, because those skills are important when it comes to animation. Acting, and whether you can do it or not, doesn't really influence your skills as an animator.

At a temperature of 280k, the gas in a cylinder has a volume of 20.0 liters.If the volume of the gas is decreased to 10.0 liters, what must the temperature be for the gas to remain at a constant pressure?

Answers

Answer:

T = 140 K

Explanation:

As we know by ideal gas law

$PV = nRT$

now if pressure of the gas is constant

then we will have

$V = (nR)/(P) T$

now we have

$V_1 = 20.0 litre$

$T_1 = 280 K$

$V_2 = 10.0 litre$

now from above equation

$(20.0)/(10.0) = (280)/(T)$

$T = 140 K$

Temperature should be 140k to maintain constant pressure

Answers

Permeability is the condition of being capable of having materials flow into and out of a membrane. The permeability of a cell membrane is determined by how easily a molecule can diffuse across the membrane. Usually, only molecules that are fat-soluble can permeate across a cell membrane. This is because the layer that is exposed on the linings of the cell membrane is nonpolar and can therefore allow the fat-soluble molecule to pass through.

Answer:Cell membranes are composed of a lipid bilayer.

Lithification is the process that produces _______ rocks

Answers

Lithification is the process that produces sedimentary rocks which show the Earth's natural past by bringing together sediments into layers of solid rock.

Lithification forms sedimentary rocks. Earth's three main rock kinds are sedimentary, igneous, and metamorphic. Sediments, microscopic particles from pre-existing rocks, minerals, organic materials, or chemical precipitates, accumulate, transport, and deposit at or near the Earth's surface.

Lithification is a multistep process. Sediments are initially deposited in riverbeds, lakes, oceans, deserts, and glaciers. As new sediments are deposited on top, these loose particles are pressured by the weight of higher layers. This pressure compacts sediments, narrowing pore gaps between particles and sticking them together.

During lithification, minerals dissolved in groundwater can precipitate and cement the sediments. Calcite, silica, and iron oxides are sedimentary rocks' main cementing minerals. Sediments become solid rock by cementation.

As pressure rises, dewatering forces water out of sediment pore spaces during lithification. This helps sediment layers compact and solidify.

Lithification creates a cohesive and cemented sedimentary rock that records historical environmental conditions, climate changes, and life on Earth. Sandstone, limestone, conglomerate, shale, and mudstone are sedimentary rocks.

Lithification is essential to the production of sedimentary rocks, changing the Earth's surface and revealing its geological past.

The source of the centripetal force required for a car to round a curve is _____.tension
gravity
friction
weight

Answers

The source of the centripetal force required for a car to round a curve is friction, I believe. This would be because the cars wheels are grinding across the ground while rounding a curve. It's not Tension, because the stretching of the wheels don't really help and although gravity/weight make the car stay on the ground, it's the fricition that makes it round a curve.

The Correct Answer Is Friction.
