Answer:
56.2 mL
Explanation:
Given data
- Initial volume (V₁): 250 mL
- Initial pressure (P₁): 1.00 atm
- Final pressure (P₂): 4.45 atm
Assuming the gas has an ideal behavior, we can find the final volume using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁/P₂
V₂ = 1.00 atm × 250 mL/ 4.45 atm
V₂ = 56.2 mL
The reality is that the mechanical energy is supposed to dissapear in this case. The mechanical energy is replaced with the knietic energy. <span>If starting from rest, the mechanical energy of the skier is entirely in the form of potential energy. As the skier begins the descent down the hill, potential energy is lost and kinetic energy is gained.</span>
Sulphuric acid (H2SO2) is a dibasic acid. It generated H+ ions when dissolved in water. In order to neutralize an acid, a base containing hydroxy ion (OH-) will be required.
NaOH, Ca(OH)2, KOH, etc. can be used to neutralize H2SO4.
If NaOH is used as a base, following reaction is initiated.
2NaOH + H2SO4 → Na2SO4 + H2O

We have to get the stable atom formed after positron emission from Terbium-147.
The stable atom is (D) ₆₄Gd¹⁴⁷.
Positron is radioactive decay. Positron is a type of beta particle β⁺.
Positron emission decreases proton number relative to neutron number, positron decay results in nuclear transmutation, changing an atom of one chemical element with an atomic number that is less by one.
Terbium on positron emission produces Gadolinium with one atomic number less than Terbium. So, the positron emission reaction is as shown below:
Tb¹⁴⁷→ ₆₄Gd¹⁴⁷ + ₁e⁰
Answer:
Fundamental Units are the units which are independent of any other unit.
They do not depend on any other physical quantity for their measurements .
Derived Units are derived from Fundamental Units.
They are are products and/or ratios of the fundamental quantities that exist in a system of units.
