1. Two charges Q1( + 2.00 μC) and Q2( + 2.00 μC) are placed along the x-axis at x = 3.00 cm and x=-3 cm. Consider a charge Q3 of
Masja [62]

Answer:

speed when it reaches y = 4.00cm is

v = 14.9 g.m/s

Explanation:

given

q₁=q₂ =2.00 ×10⁻⁶

distance along x = 3.00cm= 3×10⁻²

q₃= 4×10⁻⁶C

mass= 10×10 ⁻³g

distance along y = 4×10⁻²m

r₁ = \sqrt{3^{2} +2^{2}  } = \sqrt{13} = 3.61cm = 0.036m

r₂ = \sqrt{4^{2} + 3^{2}  } = \sqrt{25} = 5cm = 0.05m

electric potential V = \frac{kq}{r}

change in potential ΔV = V_{1} - V_{2}

ΔV = \frac{2kq_{1} }{r_{1}} - \frac{2kq_{2} }{r_{2} } , where q_{1} = q_{2}=2.00μC

ΔV = 2kq(\frac{1}{r_{1}} - \frac{1}{r_{2} })

ΔV = 2 × 9×10⁹ × 2×10⁻⁶ × (\frac{1}{0.036} - \frac{1}{0.05} )

ΔV= 2.789×10⁵

\frac{1}{2}mv^{2} = ΔV × q₃

\frac{1}{2} ˣ 10×10⁻³ ×v² = 2.789×10⁵× 4 ×10⁻⁶

v² = 223.12 g.m/s

v = 14.9 g.m/s

The group number of on the periodic table corresponds to which characteristics of the elements of that group ?
vovangra [49]

Answer:

Explanation:

In 1789, Antoine Lavoisier published a list of 33 chemical elements. Although Lavoisier grouped the elements into gases, metals, non-metals, and earths, chemists spent the following century searching for a more precise classification scheme. In 1829, Johann Wolfgang Döbereiner observed that many of the elements could be grouped into triads (groups of three) based on their chemical properties. Lithium, sodium, and potassium, for example, were grouped together as being soft, reactive metals. Döbereiner also observed that, when arranged by atomic weight, the second member of each triad was roughly the average of the first and the third.[19] This became known as the Law of Triads.[20] German chemist Leopold Gmelin worked with this system, and by 1843 he had identified ten triads, three groups of four, and one group of five. Jean Baptiste Dumas published work in 1857 describing relationships between various groups of metals. Although various chemists were able to identify relationships between small groups of elements, they had yet to build one scheme that encompassed them all.[19]
