Testing shows that a sample of wood from an artifact contains 12.5% of the original amount of carbon-14. Given that the half-life of carbon-14 is 5730 years, how old is the artifact?
A. 22,920 years
B. 17,190 years
C. 11,460 years
D. 5730 years
Answer:
B. 17,190
Explanation:
got it right, trust
The age of the artifact is 17190 years. So, the correct option is B.
What is meant by half life ?The amount of time needed for half of a radioactive sample's atomic nuclei to spontaneously decay (transform into another nuclear species by producing particles and energy) is known as the half-life.
Here,
Amount of Carbon-14 present in the given sample = 12.5 %
Given that the half-life of Carbon-14 is 5730 years. That means after a period of 5730 years, the percentage of Carbon-14 present in the sample will be 50% of the original amount.
So, age of the artifact when 50% is present is 5730 years.
Thus, after a period of 2 half-lives, the amount of carbon-14 present will be, 25%.
So, age of the artifact when 25% is present,
t = 2 x 5730 = 11460 years
Therefore, we can say that,
The age of the artifact when 12.5% is present,
t' = 3 x 5730 = 17190 years
Hence,
The age of the artifact is 17190 years. So, the correct option is B.

Minute after minute, hour after hour, day after day, ocean waves continue to splash onto the shore. Explain why the beach is not completely submerged and why the middle of the ocean has not yet been depleted of its water supply. A) Ocean waves can only bring water to the shore but cannot take it back. The momentum of the water particles switches direction when the wave hits the shore and this momentum takes all the water back into the ocean. B) Ocean waves bring the water and also take it all the way back into the ocean. As such, water does not pile up on the beach. C) Ocean waves can only bring energy to the shore; the particles of the medium (water) simply oscillate about their fixed position. D) None of the choices are correct.
Answer: C. Ocean waves can only bring energy to the shore; the particles of the medium (water) simply oscillate about their fixed position.
Explanation:
The reason why the beach is not completely submerged and the reason why the middle of the ocean has not been depleted of its water supply is due to the fact that water isn't transported by ocean waves.
It should be noted that even a single drop of water cannot be brought by the ocean wave to the shore from the middle of the ocean.
The only thing that the ocean waves can bring to the shore is energy. Hemce, the water particles oscillate in their fixed position which is vital in making sure that the beach isn't piled up with water.

a uniform metre scale rests horizontally on a knife edge at the 60cm mark when a mass of 10 gram is suspended from one end . at which end this mass be suspended . what is the mass of meter scale?
Answer:
40 gram or 0.04 kilogram
Explanation:
From the diagram attached,
The mass must be suspended at end B.
Applying the principle of moment,
Sum of clockwise moment = sum of anti-clockwise moment.
From the diagram,
Taking the moment about the pivot,
X(60-50) = 0.1(100-60)
Where X = weigth of the meter rule
10X = 4
X = 4/10
X = 0.4 N
X = 0.4/10
X = 0.04 kg
X = 40 g
Hence the mass of the meter rule = 0.04 kg or 40 gram

An ecosystem is a group of organisms and the habitat in which they live together. All organisms in an ecosystem interact with each other and their environment.
Some organisms interact as part of a food chain or food web. A food web is a complicated set of interrelated food chains all found in one ecosystem. Matter and energy are transferred from one organism to another at each step. They go through the producers like plants, which make their own food, consumers like animals, which eat other living things, and decomposers like bacteria, which break down dead organisms and help cycle energy and nutrients back into the environment.
For example, in the hot African Savannah, a herd of antelope gets energy from the grass they eat. A pride of lions chases down and consumes an antelope, gaining energy from the flesh of their prey. One of the lions is very old, and soon dies. Scavengers gain energy as they pick over his dead body. This is just one example of a string of events that is the food chain.
In the food chain described above, what are the producers?
a. the antelope that eat the grass
b. the scavengers that eat the dead lion
c. the grasses the antelope eat
d. the lions that eat the antelope
Answer:
C
Explanation:
producers must be a green plant
Answer: C
Explanation:
Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.
A car has wheels of radius of 0.380 m and they rotate once every 0.100 s. What is the linear velocity of the wheels? (Units = m/s)
Answer:
v = 23.87 m/s
Explanation:
Given that,
The radius of wheels, r = 0.380 m
The wheels rotate once every 0.1 s
We need to find the linear velocity of the wheels. The linear velocity of a wheel is given by :
[tex]v=\dfrac{2\pi r}{t}\\\\=\dfrac{2\pi \times 0.38}{0.1}\\\\=23.87\ m/s[/tex]
So, the required linear velocity of the wheel is equal to 23.87 m/s.

A proton is 0.9 meters away from a 1.4 C charge. What is the magnitude of the electric force between the proton and the charge
Answer:
F = 2.49 x 10⁻⁹ N
Explanation:
The electrostatic force between two charged bodies is given by Colomb's Law:
[tex]F = \frac{kq_1q_2}{r^2}\\[/tex]
where,
F = Electrostatic Force = ?
k = colomb's constant = 9 x 10⁹ N.m²/C²
q₁ = charge on proton = 1.6 x 10⁻¹⁹ C
q₂ = second charge = 1.4 C
r = distace between charges = 0.9 m
Therefore,
[tex]F = \frac{(9\ x\ 10^9\ N.m^2/C^2)(1.6\ x\ 10^{-19}\ C)(1.4\ C)}{(0.9\ m)^2}[/tex]
F = 2.49 x 10⁻⁹ N

What is the temperature increase of 4.0 kg of water when it is heated by an 8.0 ^102 W immersion heater for exactly 10.0 min? (cp = 4186 J/kg·°C)
Answer:
ΔT = 28.667°C is the answer.
Explanation:
Given,
Mass of water = 4.0 kg
Water is heated by = 8 × 10² W = 800 W
Time = 10 min = 10 × 60 = 600 s
Now,
using the equation of specific heat,
Q = mcΔT
where c is the specific heat capacity of water = 4186 J/kg°C
Q = Pt
Substituting,
Pt = mcΔT
800 × 600 = 4 × 4186 × ΔT
480000 = 16744 × ΔT
ΔT = 28.667
∴Temperature increased, ΔT = 28.667°C

John often sees squiggly lines when he looks at a bright sky or white paper. His doctor says that they are called eye floaters, which are small bits of protein in the fluid that fills the eyeball.
In what part of the eye are eye floaters found?
a) cornea
b) vitreous humor
c) retina
d) convex lens
Answer- It's B, i double checked it on a few websites
The vitreous humor is the eye is eye floaters.
What is vitreous humor?The vitreous body (vitreous meaning "glass-like"; from Latin vitreus 'glassy', from vitrum 'glass', and -eus) is the clear gel that fills the space between the lens and the retina of the eyeball (the vitreous chamber) in humans and other vertebrates. It is often referred to as the vitreous humor (also spelled humour, from Latin meaning liquid) or simply "the vitreous". Vitreous fluid or "liquid vitreous" is the liquid component of the vitreous gel, found after a vitreous detachment. It is not to be confused with the aqueous humor, the other fluid in the eye that is found between the cornea and lens.
StructureThe vitreous humor is a transparent, colorless, gelatinous mass that fills the space in the eye between the lens and the retina. It is surrounded by a layer of collagen called the vitreous membrane (or hyaloid membrane or vitreous cortex) separating it from the rest of the eye. It makes up four-fifths of the volume of the eyeball.The vitreous humour is fluid-like near the centre, and gel-like near the edges.
