#b. 0.0977 g

#a.

Titanium-51 is the radioisotope that undergoes Beta emission to emit a daughter isotope Vanadium-51 (Mass number-51 and atomic number -23).

Titanium-51 has a mass number of 51 and atomic number of 22.

A beta particle is equivalent to ⁻¹₀e

Beta emission does not affect the mass number of an isotope but increases the atomic number by 1.

Therefore;

The reaction will be;

⁵¹₂₂Ti +  ⁻¹₀e → ⁵²₂₂V

#b.

The half life of Ti-51 is 6 minutes

We can calculate the mass remaining after 1 hour (60 min)

Original mass of the sample = 10.0 g

But; using the formula;

Remaining mass = Original mass × (1/2)^n , where n is the number of half lives.

in this case, n = time/half life

= 60 min ÷ 6 min

= 10

Therefore;

Remaining mass = 100 g × (1/2)^10

The typical hydrogen content (by mass) of stars that are forming right now in the vicinity of the sun is 75% hydrogen.

What is hydrogen?
The chemical element hydrogen is represented by the letter H as well as atomic number 1. The lightest element is hydrogen. Under normal circumstances, hydrogen is a gas made up of diatomic molecules with the formula H2. It is non-toxic, tasteless, colourless, odourless, and highly combustible. In the universe, hydrogen is by far the most prevalent chemical, making up about 75% of all ordinary matter. Plasma hydrogen makes up the majority of stars like the Sun. On Earth, hydrogen mostly takes the form of molecules like water and biological compounds. Each atom of hydrogen's most prevalent isotope, 1H, contains a single proton, one electron, and also no neutrons.

This is because the interstellar medium contains mostly hydrogen, which is the most abundant element in the universe. When these clouds of gas and dust collapse, they become denser and hotter, and the hydrogen atoms begin to fuse together, creating helium and other elements in the process.

What is internal energy?
Rising temperature and changes in state as well as phase from solid to liquid as well as liquid to gas cause an increase in internal energy. Planetary bodies can be viewed as a fusion of heat engines and heat reservoirs. Internal energy E is stored in the heat reservoirs, and some of it is converted into different kinds of mechanical, electrical, and chemical energies by the heat engines. The sum of the kinetic energy brought on by the motion of molecules as well as the potential energy brought on by the vibrational motion as well as electric energy of atoms inside of molecules makes up the internal energy U of the a system or a body with clearly defined boundaries. The energy contained in every chemical bond is also referred to as internal energy.

The change in the internal energy of the engine can be calculated using the First Law of Thermodynamics, which states that the increase in the internal energy of a system equals the work done by the system plus the heat added to the system. In this case, the work done by the engine is 508 joules and the heat generated by the engine is 2277 joules. Therefore, the change in the internal energy of the engine is 508 + 2277 = 2785 joules.

What is energy of electrons in a shell?

The energy level of each electron shell varies, with the electron shells nearest to the nucleus having a lower energy level than those farthest from the nucleus. If the electron jumps from the second energy level down to the first energy level, it must give off some energy by emitting light.

What is wavelength and how to calculate it?

Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.

Rydberg's Formula for calculating the wavelength:

1 / λ = R(Z - [tex]1^2[/tex]) [tex][\frac{1}{1} - \frac{1}{n^2} ][/tex]

Energy associated with the electron in the K-shell is approximately

[tex]E_k = -(74-1)^2(13.6eV) = -72474eV[/tex]

The number of electrons in the n = 1 and n = 2 states, which act as a shield between the M electrons and the nucleus. M electrons are protected from the nucleus by about nine electrons because there are currently eight electrons in the n = 2 state and one electron in the n = 1 state.

[tex]Z_eff = z - 9[/tex]

Consequently, the energy of an electron in the M shell is

[tex]E_m = \frac{-13.6 z_eff^2}{3^2}[/tex]eV = [tex]E_m = \frac{13.6 (z-9)^2}{3^2}[/tex]

[tex]E_M =[/tex] -6384eV

Therefore, emitted X-ray has an energy equal to

[tex]E_m - E_k = {-6384-(-72474)}eV[/tex]

               = 66090eV = 66KeV

To calculate wavelength,

For an electron in the Kshell, σ=1.

Thus, Zeff = Z−σ = Z−1

Here, as electron drops from Mshell(n=3) → Kshell(n=1), we call the radiated emission Kβ X-ray and from is given as

The mass of the sloth is m= 4 kg and it climbs a height of h = 6 m in Δt=20 min 120 s.

Let its initial height be the zero gravitational potential energy level y=0; So its final height is yf = h

So, from equation (2), the change in the sloth's gravitational potential energy is:
