m = mass of the particle = 2 x 10⁻³⁰ kg
Δv = uncertainty in velocity of the particle = 10² m/s
Δx = uncertainty in position of the particle = ?
h = plank's constant = 6.63 x 10⁻³⁴ J-s
uncertainty principle is given as
m Δx Δv ≥ h/(4π)
inserting the values
(2 x 10⁻³⁰) Δx (10²) ≥ (6.63 x 10⁻³⁴)/(4(3.14))
Δx ≥ 2.64 x 10⁻⁷ m
so minimum possible uncertainty is 2.64 x 10⁻⁷ m
You have to read the passage and compare and contrast the story
It is true that the iron recommendation for girls exceeds that of boys during adolescence.
During an adolescence, girls and boys require iron for a large growth spurt and the gain of adult phenotypes and biologic rhythms.
In this period of the life, iron recommendation increase in both girls and boys, because of the increase in lean body mass, the expansion of the total blood volume, the increase and start of menstruation at girls.
Iron is essential for oxygen transport, red blood cell creation, cognitive performance and immunological function.
The overall iron requirements for girls are up to twice as boys.

i think the greater the electric charge the atom decreases in size
Answer:
<u>C) 4</u>
Explanation:
<u>The reaction</u> :
- C (s) + 2H₂ (g) ⇒ CH₄ (g)
12g 4g 16g
Hence, based on this we can say that : <u>2 moles of hydrogen gas are needed to produce 16g of methane.</u>
<u />
<u>For 32g of methane</u>
- Number of moles of H₂ = 32/16 × 2
- Number of moles of H₂ = <u>4</u>
