Answer:

The answer to your question is: a. pentose

Explanation:

a) a pentose is a monosaccharide that has 5 carbons in its structure, if we look at the question the chemical formula only has 5 carbons, then this is the right answer.

b) an oligosaccharide is a group of 2 or more monosaccharides (till 5 or 6) then, it will have 10 or more carbons, this is not the right answer

c) a triose is a monosaccharide that has only three carbons, this is not the right answer.

d) a hexose is a monosaccharide that has 6 carbons, of course this answer is wrong.

e) a polysaccharide is a group of 6 or more monosaccharides, it will have 20 or more carbons, this answer is wrong.

Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pr

Delvig [45]

<h2>Hello!</h2>

The answer is: Charle's Law.

The law that states that the volume and absolute temperature of a fixed quantity of gas (ideal gas) are proportional under constant pressure is the Charle's Law, also known as the law of volumes.

The law describes how a gas kept under constant pressure tends to expand when the temperature increases and it's described by the following equation:

$\frac{V}{T}=k$

Where,

$V=Volume\\T=Temperature\\k=constant$

Also, to describe the relationship between two differents volumes at different temperatures, we have:

$\frac{V_{i}}{T_{i}}=\frac{V_{f}}{T_{f}}$

Where,

$V_{i}=InitialVolume\\T_{i}=InitialTemperature\\V_{f}=FinalVolume\\T_{f}=FinalTemperature$

Have a nice day!

Jack is playing with a Newton's cradle. As he lifts one ball to position A and drops it, it impacts the other balls at position

svetlana [45]

Answer:

Newton's Cradle is a neat way to demonstrate the principle of the CONSERVATION OF MOMENTUM.

What happens here is when the ball on one end of the cradle is swung and it hits the other balls that are motionless, or stationary, the momentum of the swinging ball is transferred to the next ball upon impact.

Momentum is not lost in this action, what happens when it hits the next ball, the momentum is transferred to the next one, and then the next, and the the next, till it reaches the last ball on the other end. Since nothing is next to the last ball, it pushes the ball upwards, which will swing down and repeat the process going the other way.

This also demonstrates the CONSERVATION OF ENERGY. As you will see, the energy continues to move through the other balls, passing it from one ball to the other, which keeps this constantly moving.

The half life for the decay of carbon-14 is 5.73 x 10 years. Suppose the activity due to the radioactive decay of the carbon-14

Elena-2011 [213]

Answer:

Age of the atifact is $4.2\times 10^{2}$ years

Explanation:

For first -order radioactive decay- $A_{t}=A_{0}(\frac{1}{2})^{\frac{t}{t_{\frac{1}{2}}}}$
$A_{t}$ represents activity of radioactive nuclide after t time, $A_{0}$ represents initial activity of radioactive nuclide and $t_{\frac{1}{2}}$ represents half-life
Here, $A_{t}=19Bq$ , $A_{0}=20Bq$ and $t_{\frac{1}{2}}=5.73\times 10^{3}years$
