Answer:

B.nucleon

Explanation:

Nucleons are called neutrons and protons. Nucleons constitute the nucleus of the atom. They were considered as elementary particles, however, they could be made up of quarks. Today it is known that they are particles formed by three quarks that are joined by a force by gluons. Its mass is as much the mass of quarks as gluons.

Answer: The final volume V_2 is 263.09 ml

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=156ml\\T_1=215^oC=(215+273)K=488K\\V_2=?\\T_2=550^0C=(550+273)K=823K

Putting values in above equation, we get:

\frac{156}{488}=\frac{V_2}{823}\\\\V_2=263.09ml

Thus final volume V_2 is 263.09 ml

Chromium-51 is a radioisotope that is used to assess the lifetime of red blood cells The half-life of chromium-51 is 27.7 days.
8090 [49]

Answer:

11.9g remains after 48.2 days

Explanation:

All isotope decay follows the equation:

ln [A] = -kt + ln [A]₀

<em>Where [A] is actual amount of the isotope after time t, k is decay constant and [A]₀ the initial amount of the isotope</em>

We can find k from half-life as follows:

k = ln 2 / Half-Life

k = ln2 / 27.7 days

k = 0.025 days⁻¹

t = 48.2 days

[A]  = ?

[A]₀ = 39.7mg

ln [A] = -0.025 days⁻¹*48.2 days + ln [39.7mg]

ln[A] = 2.476

[A] = 11.9g remains after 48.2 days

Ventilation is governed by Boyle's Law, which states that at a constant temperature Multiple choice question. the solubility of
VikaD [51]

Answer:

the pressure of a gas is directly proportional to its volume.

Explanation:

Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Where;

P1 is the original pressure.

P2 is the final pressure.

V1 is the original volume.

V2 is the final volume.

This ultimately implies that, ventilation which is typically governed by Boyle's Law, which states that at a constant temperature the pressure of a gas is directly proportional to its volume.
