From the following options, the reasonable numerical ages for a mammoth bone is: D. 17,000 y.b.p.

Radiocarbon dating (¹⁴C) is one of the most reliable dating methods for organic materials such as fossil bones, shells, plant remains, charcoal, etc. This method uses ¹⁴C isotopes to measure the half-life of fossils. This way, we can calculate a reliable numerical age for those fossils.

Mammoth is an already extinct prehistoric mammal, which was an ancestor of the elephant. By the radiocarbon dating measurement, experts conclude that they were live on the cold tundra of North America, Europe, and Asia from around 42,000-10,000 y.b.p. Hence, the most reasonable numerical age for a mammoth is 17,000 y.b.p.

Complete Question

Planet D has a semi-major axis = 60 AU and an orbital period of 18.164 days. A piece of rocky debris in space has a semi major axis of 45.0 AU.  What is its orbital period?

Answer:

The value  is  \(T_R = 11.8 \ days\)  

Explanation:

From the question we are told that

   The semi - major axis of the rocky debris  \(a_R = 45.0\ AU\)

   The semi - major axis of  Planet D is  \(a_D = 60 \ AU\)

    The orbital  period of planet D is  \(T_D = 18.164 \ days\)

Generally from Kepler third law

          \(T \ \ \alpha \ \ a^{\frac{3}{2} }\)

Here T is the  orbital period  while a is the semi major axis

So  

        \(\frac{T_D}{T_R} = \frac{a^{\frac{3}{2} }}{a_R^{\frac{3}{2} }}\)

=>     \(T_R = T_D * [\frac{a_R}{a_D} ]^{\frac{3}{2} }\)  

=>     \(T_R = 18.164 * [\frac{ 45}{60} ]^{\frac{3}{2} }\)

=>      \(T_R = 11.8 \ days\)  

The orbital period of the rocky debris in space is 12 days.

From Kepler's law, we know that the square of the period of a planet in years is equal to the cube of its mean distance from the sun in astronomical units (AU).

Mathematically;

\(T^2 = r^3\)

Now, we have the mean distance as 45.0 AU, we need to obtain its period.

semi major axis of debris rR= 45.0 AU

semi major axis of planet D rD = 60 AU

Period of planet D  TD  = 18.164 days

Period of debris TR = ?

\(\frac{TR^2}{TD^2} = \frac{rR^3}{rD^3}\)

\(\frac{rR^3}{rD^3} * TD^2\)

\(TR^2 = 45^3/60^3 * 18.164^2\)

TR = 12 days

Missing parts:

Planet D has a semi-major axis = 60 AU and an orbital period of 18.164 days. A piece of rocky debris in space has a semi major axis of 45.0 AU.  What is its orbital period?

The minimum index of refraction of the prism is 1.414.

What does light ray is incident mean?

Light ray incident is a term used to describe when a light ray strikes a surface. This can refer to light from any source, such as the sun, a light bulb, or a laser. When light rays are incident on a surface, they may be reflected, absorbed, or transmitted. The behavior of the light depends on the properties of the surface, such as its color, texture, and composition.

This double internal reflection requires that the angle of incidence (45º) at the 1st prism side is at least = critical angle. This reflected ray then meets the other prism side at the same angle of incidence (45º). so we only need to consider the first internal reflection.

Applying [ n sin i = constant ] to the prism-air boundary.

(np= ref.index for prism material, nₒ = ref.index for air =1.0 )

At a critical angle of incidence 45º, external angle = 90º

np sin 45 = nₒ sin90

np = nₒ sin90 / sin45=1 x 1 / 0.7071

np(min) = 1.414

Therefore, 1.414 is the minimum index of refraction of the prism.

(a) Yes, our velocity changes because the direction is changing. (b) No, we do not accelerate.

(a) Velocity is a vector quantity that includes both magnitude (speed) and direction. When we round a curve and drive east, the direction of our motion changes.

Therefore, even if our speed remains constant, the velocity vector changes because it now points in the eastward direction instead of the previous direction.

(b) When the magnitude of the direction of the velocity is changed, we say that acceleration has occurred. In this scenario, although the direction of your velocity changes, your speed remains constant.

Since the rate at which velocity changes determines acceleration, there cannot be acceleration without a change in velocity.

If the starship drops the engine force output to 3000 N of force he ship's acceleration going to be at acceleration, a = 4.28 m/s².

In the given equation we can see the different force working on engine so,

To find the acceleration first we need the mass of engine

Using formula,

F = m x v

10,000 - 3000 N = m x 10 m/s

7000N = m x 10 m/s

m = 700 kg

Now as we have mass of the engine,

By the formula,

a = F / m

F = 3000 N

m = 700 kg

So, putting values we have :

a = 3000 / 700

Answer:

its when a liquid, prolly water, turns into a vapor !!

Explanation:

and nice pic uwu

A liquid turning into a gas is evaporation. It is how water gets from the surface of the Earth to the atmosphere.

Latent heat is a form of energy held in the evaporated water when it evaporates and cools.

Evaporation plays a significant role in the energy exchange that results in atmospheric motion, affecting weather and climate in the Earth-atmosphere system.

The particles with the highest kinetic energy are the first to evaporate from a liquid.

Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

We can find the current I(3torque) at a time after t=0 equal to three times the time constant using the formula for the current in a charging RC circuit:

I(t) = I0 * e⁻ᵗ/RC)

where I0 is the initial current, t is the time, R is the resistance, and C is the capacitance.

Since we are given that I(3torque) = 3 * RC, we can set up the equation:

3 * RC = I0 * e⁻³ᵗ/ RC)

We can solve for I0 by dividing both sides by ee⁻³ᵗ/RC):

I0 = 3 * RC / e⁻³ᵗ/RC)

We can simplify this expression by multiplying the numerator and denominator by e³ᵗ/RC):

I0 = 3 * RC *e⁻³ᵗ/RC) / e

I0 = 3 * RC * e ³ᵗ/RC)

Therefore, the current I(3torque) at a time after t=0 equal to three times the time constant is:

I(3torque) = I0 * e⁻³/RC)

I(3torque) = 3 * RC * e3/RC) * e³/RC

I(3torque) = 3 * RC * e⁰

I(3torque) = 3 * RC

Therefore, the current I(3torque) at a time after t=0 equal to three times the time constant is simply 3 times the time constant, without any dependence on the value of t.

To calculate the observer's frequency (Fo), you need to know the source frequency (Fs), the velocity of sound (V), and the relative velocity between the source and observer (Vr). The formula for Fo is Fo = Fs x ((V + Vr)/V).

The observer's frequency (Fo) is calculated based on the Doppler effect, which is the shift in frequency that occurs when the source and observer are in relative motion. The source frequency (Fs) is the original frequency of the sound wave emitted by the source. The velocity of sound (V) is the speed at which sound travels in a given medium, such as air. The relative velocity between the source and observer (Vr) is the speed at which the observer is moving towards or away from the source. The formula for Fo takes into account all of these factors to determine the frequency that the observer will hear.

The Doppler effect is a phenomenon that occurs when the frequency of a sound wave changes due to the relative motion of the source and the observer. In this formula, positive values for vo indicate that the observer is moving towards the source, while negative values indicate that the observer is moving away from the source. Similarly, positive values for vs indicate that the source is moving away from the observer, while negative values indicate that the source is moving towards the observer.

Answer:

The frequency will still remain F

Explanation:

Firstly, we should remember that the frequency of a simple harmonic oscillator doesn't depend on the amplitude. Rather, it depends on the spring constant, k, and the mass of the attached weight, m. This means that the change in amplitude will not lead to a corresponding change in frequency.

the frequency is represented by the formula

f = 1/2π * √(k/m),

where

f = frequency of the oscillator

k = spring constant and

m = mass attached to the spring

From the formula above, we can state that the frequency doesn't depend on the amplitude at all, and as such, the amplitude changing from A to 2A, will effect no change in the frequency F.

Explanation:

Answer:

The answer to your question is: When you touch the vibrating metal, the flesh of your finger absorbs the energy quickly, so the sound dies away quickly, pretty much instantly in fact.

Explanation:

When you set a bell ringing, the metal body itself vibrates. It launches those vibrations into the air to create the sound you hear. Because the air is comparatively thin, it loses energy only slowly, so the sound dies away slowly.

Radioactive element  which keeps on decaying over the time. Decay of radioactive element always comes under first order kinetics. Therefore the half life time of  radioactive substance is 2seconds.

Half life tells about the time at which the radioactive material decays to half of its initial concentration.

Mathematically,

half life time=0.693/  rate constant of the decay

The half life of a radioactive substance is the time taken for the activity to halve. Using the graph to calculate the half life of the radioactive isotope, we find that activity that is 3500 so, half of this activity is 17500 which is corresponding to time 2 seconds.
