Answer:

Beats is a phenomenon which occurs when two sound waves with different frequencies overlap each other.

Explanation:

When these two sound waves overlap, a third frequency is formed. The places where the two waves reinforces each other, constructive interference takes place and a louder sound is produced whereas, at points where destructive interference takes place a softer sound is produced.

These alternative loud and soft sounds are called beats.

True/false: you should begin viewing a specimen with the 10x objective lens.

You should begin viewing a specimen with the 10X objective lens that is false.

<h3>What is a lens?</h3>

An optical device known as a lens uses refraction to focus or disperse a light beam. A compound lens is made up of multiple simple lenses (elements), typically aligned along a common axis, as opposed to a simple lens, which is one solid piece of transparent material. Glass or plastic are used to make lenses, which are then polished or molded into the required shape. In contrast to a prism, which just refracts light without focusing it, a lens can focus light to create an image. In addition to focusing visible light, lenses can also be used to disperse various types of waves and radiation, such as explosive, microwave, electron, and acoustic waves.

A spring with spring constant 31 N/m is attached to the ceiling, and a 4.5-cm-diameter, 1.5 kg metal cylinder is attached to its
aalyn [17]

Answer:

0.315758099469 m

Explanation:

m = Mass of cylinder = 1.5 kg

\rho = Density of water = 1000 kg/m³

V = Volume = Ah

A = Area = \pi r^2

k = Spring constant = 31 N/m

x = Displacement

g = Acceleration due to gravity = 9.81 m/s²

Here the forces are conserved

Weight of cylinder = Buoyant force + Spring force

mg=\rho Vg+kx\\\Rightarrow mg=\rho Ahg+kx\\\Rightarrow 1.5\times 9.81=1000\times \pi(2.25\times 10^{-2})^2x\times 9.81+31x\\\Rightarrow 1.5\times 9.81=46.60213x\\\Rightarrow x=\dfrac{1.5\times 9.81}{46.60213}\\\Rightarrow x=0.315758099469\ m

The length of the submerged cylinder is 0.315758099469 m

If you were to find 2 fossils, give the reasons for the way you might be able to tell which fossil is older?
sineoko [7]

Answer:

Relative Dating

Explanation:

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
