What is the standard unit of frequency
Amplitude
Hertz
Period
Second

Answers

Answer 1
Answer: Hertz. And since I need 20 characters I’ll give fascinating facts. To find the velocity of a wave you multiply lambda by frequency. Frequency can be found by dividing energy by planks constant ( 6.626x10e-34) or speed divided by wavelength.

If the density of mercury is 13.5 g/cm³ in the gram per centimeter cube unit, then the density of the mercury would be 1.35×10⁴ in the kilograms per cubic meter

What is density?

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

By using the above formula for density

ρ = mass / volume

As given in the problem If the density of mercury is 13.5 g/cm³ in the gram per centimeter cube unit then we have to convert its value into kilograms per cubic meter.

1000 grams  = 1 kilogram

1 gram = 1/1000 kilograms

           =1×10⁻³ kilograms

10⁶ cubic centimeter = 1 cubic meter

1  cubic centimeter = 1/10⁶  cubic meter

                                = 1× 10⁻⁶ cubic meter

Given the density of the mercury  13.5 g/cm³

13.5 g/cm³ =  13.5 ×10⁻³ kilograms / 1× 10⁻⁶ cubic meter

                   = 1.35×10⁴ kilograms / cubic meter

Thus, we converted the density of mercury is 13.5 g/cm³ into 1.35×10⁴ kilograms / cubic meter

Explanation:

Is it possible to estimate densities of liquids in a container by holding them in your hand? Explain.

Answers

No, Because if u do that it wouldn't be the right amount of density. So therefore your density will be wrong.

An organism's scientific name consists of...

Answers

Answer:

binomial nomenclature.

Explanation:

This means that an organism's scientific name is a combination of two terms.

The first is the name of the organism's genus, and the second is the name of the organism's species

together the genus and the species create the name of a single organism.

What is the direction of transfer of energy in the waves produced?

Answers

Transverse waves occur when a disturbance causes oscillationsperpendicular (at right angles) to the propagation (the direction of energy transfer). Longitudinal waves occur when the oscillations are parallel to the direction of propagation.
