Explanation:

Answer:

Exactly 0.03042 carbon-14 is remaining.

Roughly 0.03 Carbon-14 is remaining. (When/If Multiple Choice)

Explanation:

Not a physics question, this is chemistry, but I'll answer.

First, divide 17,000/5700 to find the t, or time.

t = 2.98245614 or 2.98.

If it originally contained .24 grams, and a half life means x/2,

you would use the formula x/2^p, with p being the number of half lives

(these variables are made up, you can use any you would like)

In 17,000 years, the palm fossil experienced 2.98 half lives.

Thus meaning, using our equation, we would find (.24)/2^2.98

This equals 0.030418784 carbon-14 remaining to be exact.

(For Multiple Choice, it may be required to round to For Multiple Choice, it may be required to round to 3, so .24/2/2/2 or .24/2=.12 then .06 then it equals :  .03 Carbon-14)

Carbon -14 is used to date a palm fossil that originally contained 0.24 grams of carbon -14. The half life is 5700 years. If the fossil is found to be 17,100 years old then 0.0303 g of carbon -14 does it contain now.

The process by which an unstable atomic nucleus loses energy through radiation is known as radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration). A radioactive substance is one that contains unstable nuclei. Alpha decay, beta decay (-decay), and gamma decay (-decay) are three of the most prevalent forms of decay, all of which entail the emission of one or more particles. The mechanism responsible for beta decay is the weak force, while the other two are regulated by electromagnetism and nuclear force. Electron capture is a fourth form of common decay in which an unstable nucleus grabs an inner electron from one of the electron shells.

According to decay formula,

N(t) = N₀ e^(-λt)

Given,

N₀ = 0.24g

t = 17100 years

λ = 0.693/T

Where T is half life.

λ = 0.693/5700 = 1.21 × 10⁻⁴

Putting all the values in the equation,

N(t) = 0.24g e^(-1.21 × 10⁻⁴ ×17,100)

N(t) = 0.0303 g

The magnitude of the force applied by the wall on the ball while smashed is 38.462 newtons.

After a quick reading of the statement we conclude that the impact theorem shall be useful to determine the dynamic force required to stop the ball when smashed. The impulse theorem results from the combination of the Newton's laws of motion, principle of energy conservation and work-energy theorem:

Where:

If we know that m = 1 kg, [tex]v_{o} = 5\,\frac{m}{s}[/tex] and Δt = 0.13 s, then the impact force is:

Natural selection could act on a population of proto-cells on early Earth, selecting for those that were stable and had self-replicating, catalytic RNA that allowed them to grow and divide to produce similar daughter proto-cells. The correct option is option (B).

Natural selection could act on a population of proto-cells on early Earth. Proto-cells were early, simpler forms of cells that lacked DNA but had self-replicating, catalytic RNA. Through natural selection, those proto-cells that were more stable and had RNA molecules capable of self-replication and catalytic functions would have had a reproductive advantage.

These traits would allow them to grow, divide, and produce similar daughter proto-cells. Over time, this selection process could have led to the development of more complex and stable cellular structures, eventually leading to the emergence of cells that utilize DNA as their genetic material.

The Speed of the throw that is required to create enough impulse, to change the direction of the momentum is: -1.81m/s

Explanation:

m1=95kg

m2=21kg

V1=.4m/s

V2=?

V'=<0 or -.01 at lowest.

for the Impulse formula, I found: m1 x V1 + m2 x V2 = <0

so,

(95) x (.4) + (21) x (V2)=<0

38kgm/s+(21kg x V2)=<0 or -0.01m/s

I found that V2 was equivalent to -1.81, and when you plugin the value, you get the equation

(95) x (.4) + (21) x (-1.81) = -0.01m/s
