Answers

Answer:

34.611g

Explanation:

mass of metal = ?

density of metal = 1.39/cm³

volume = 24.9 cm³

density = mass/volume

mass = density × volume

= 1.39g/cm³ × 24.9 cm³

= 34.611g

how are subtances dissolved ?​

Answers

Answer: A solute dissolves because its particles interact with the particles of a solvent. Anything that allows more solvent to touch more solute will cause a solute to dissolve more quickly. Small pieces of a substance dissolve faster than large pieces.

Which statement best supports the idea that water conservation is important for human societies?

OA Once humans use water, it cannot be reused ever again,

OB. Only about 1% of the freshwater on Earth is easily accessible.

OC Water is constantly being lost from the hydrosphere

OD. Most land animals use salt water instead of freshwater.

Answers

Answer:

Only about 1% of the freshwater on Earth is easily accessible.

Explanation:

Freshwater accounts for a minimal proportion of water resources on planet earth. About 70 percent of the world surface area  is covered by water, but only  about 2.5 percent of this mass of water is fresh. The remaining are marine or salt water. Amazingly, just about 1 percent of this  freshwater is easily accessible. The other 1.5% is trapped in glaciers and snowfields.

This underscore the need for water conservation on the planet since fresh water is a scarce resource and people living in many areas have no access to fresh water.

A) The intensity of the light is simply dimmed

B)The planes of light become scattered

C)The scattered light has either the horizontal plane or the vertical plane blocked

D)The intensity of the light is brighten

Answers

Answer:

C)The scattered light has either the horizontal plane or the vertical plane blocked

Explanation:

When light becomes plane polarized, it means that light is made to vibrate in only one plane.

Light usually vibrate in vertical and horizontal directions but when light becomes polarized, either the vertical or horizontal direction is blocked and it is made to vibrate in only one direction

A sound wave has a frequency of 20 Hz and a wavelength of 100 m. What is speed of the wave

Answers

The speed of a wave can be calculated using this formula:

v = f x λ

Where:

v is the wave speed in metres per second, m/s

f is the frequency in hertz, Hz

λ (lambda) is the wavelength in metres, m

Calculation:

Given:

f = 20 Hz

λ = 100m

Using the equation:

v = f x λ

v = 20 x 100

v = 2000 m/s

Therfore, the speed of the wave is 2000 m/s

A sound wave has a wavelength of 100 m and a frequency of 20 Hz. The wave's speed is 2× 10^3 m/s.

assuming frequency = 20 Hz and wavelength = 100 m

utilized concept: v= = 20×100 = 2×10³ m/s

Why is frequency important?

The frequency in physics is the quantity of waves passing a fixed location in a unit of time. It also indicates how many cycles or vibrations a body in periodic motion experiences in a given unit of time.

How would you define sound?

A sort of energy created by vibrations is sound. The molecules of the air surrounding an item vibrate as a result.. These molecules vibrate because they collide with nearby molecules, which also vibrate as a result.

What information does not need to be included a chemical waste label? Select one: Relative amounts of chemical compounds in the container. The date the waste container was filled completely. A description of the experiment the chemicals were used for. Names of the chemical compounds present in the container.

Answers

Answer:

A description of the experiment the chemicals were used for.

Explanation:

A chemical waste label is required to provide information about any hazardous waste present in the container. Some details are mandatory to mention of the chemical waste label to prevent any accident while doing the experiment, that includes:

Chemical compound's name present in the container.Composition and physical state of the waste.Hazardous properties of the waste.The date of manufacturing.Amount of chemical compounds filled in the container.

A chemical waste label does not mention or describe the experiment for which the chemicals were used for, scientists, teacher or students should have knowledge of the chemical composition by reading their names and evaluate themselves on which chemical should be used for which experiment.

Hence, the correct answer is  "A description of the experiment the chemicals were used for."

The correct answer is A description of the experiment the chemicals were used for.

A chemical waste label must contain all the information about any hazardous waste present in the container. It should clearly indicate the composition of the waste, the date of manufacturing and the amount of chemical compounds filled in the container. A chemical waste label does not need to mention the experiment for which the chemicals were used.

Calculate the energy of a photon with a frequency of 2.36 x 10-19 Hz.

Answers

Answer:

Explanation:

energy for photon is calculated in same wasy as for electromagnetic radiation

energy for electromagnetic radiation = hf

where f is the frequency of photon

h is Planck's constant = h = 4.14 × 10−15 eV · s.

thus

energy of photon = 4.14 × 10−15 eV · s *  2.36 x 10-19 Hz

energy of photon = 9.77 * 10−(-15+ -19) eV

energy of photon = 9.77 * 10−34eV        answer

With radiocarbon dating, scientists compare an object's carbon-14 levels with _____. the carbon-14 levels of an object from the same time period carbon-14 levels in the atmosphere the carbon-14 levels in the rock surrounding the object the object's carbon-12 levels

Answers

Answer:carbon-14 levels in the atmosphere

Explanation:

When carrying out radiocarbon dating, the level of carbon-14 in a sample is compared with the level of carbon 14 in the atmosphere because, objects exchange carbon-14 with the atmosphere.

Comparison of the activities of carbon-14 in the atmosphere and in the sample gives the age of the sample since the half-life of carbon-14 is a constant.
