A liquid has a volume of 225 mL and a mass of 150 g. What is its density? Round your answer to 2 decimal places.

Answers

Answer:

The answer is 0.67 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question we have

[tex]density = \frac{150}{225} = \frac{2}{3} \\ = 0.66666666...[/tex]

We have the final answer as

0.67 g/mL to two decimal places

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.

a piece of metal has a mass of 1.3 g/cm and a has a volume of 24.9 cm3 what is its mass

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

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

Which of the following properly explains what takes place when light hits polarized film?

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

Answer:

Some of the physical and chemical properties of magnesium are:

-The term ‘magnesium’ is derived from the Greek word magnesia, which refers to the name of the place from where it was extracted.

-Magnesium is closely related to manganese and magnetite.

-About 2.1% of the Earth’s crust contains magnesium. This makes magnesium the 6th most found element.

-The biggest deposits of magnesium is found in the seawater. It has been calculated by scientists that a cubic mile of seawater contains about 6 million tons of this element

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.
