Answer:
0.2 m
Explanation:
magnetic force = centripetal force
qvB = mv² / r
cancel v on both side and make r subject of the formula
r₁ = mv / qB where m = mass of ion, v = velocity of the ion
r₁ = ( 235 × 1.67 × 10⁻²⁶ × 2.81 × 10⁵) / ( 1.6 × 10⁻¹⁹ × 0.605 T) = 1139.24 × 10⁻² = 11.4 m
r₂ = ( 238 × 1.67 × 10⁻²⁶ × 2.81 × 10⁵) / ( 1.6 × 10⁻¹⁹ × 0.605 T) = 1153.78 × 10⁻² = 11.5 m
D, distance between the impact points formed = d₂ - d₁ where d₂ and d₁ represent the diameters of the charged ions
D = (2 × 11.5 m) - ( 2 × 11.4) = 2 ( 11.5 - 11.4) = 0.2 m
Answer:
A
Explanation:
i feel it is correct
in the sense that it dwpends on the presence of 4different antigens
Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction. So look for a scenario in which something had force applied upon it and the reaction is a force in the opposite direction of the same size.
Answer:
Explanation:
a) because it's immoral as you're trying to convince people of your views when you should be giving both sides of the story so people are able to come up with their own opinions on what you're talking about
