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

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.
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
Explain why warm air temperature has lower air pressure than cold air?
Answers
Answer:
Differences in temperature cause differences in air density. Warmer air is less dense than cold, which is why warm air tends to rise and cold air sinks.
temparature affects particles. warm particles are more spread out.
Explanation:
. Being acted on by gravity, colder, denser air weighs more and exerts greater pressure per unit area.

Physical and Chemical Properties of Magnesium
Here is an EXAMPLE of how it has to be like. Instead of Mercury, you HAVE to do Magnesium
Physical Properties of Mercury: ”I’m a highly stable element, so you can count on me”
Chemical Properties of Mercury: ”I love to travel but I do corrode aluminum so we won’t be flying off on adventures in airplanes planes anytime soon”
Answers
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

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/mLExplanation:
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 placesHope this helps you

Using the formula M=dx v, Calculate the mass of a liquid with a density of
17.5 g/mL and a volume of 7mL.
Answers
Answer:
The answer is 122.5 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume = 7 mL
density = 17.5 g/mL
We have
mass = 17.5 × 7
We have the final answer as
122.5 gHope this helps you

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

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.

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.
