First, find length of AB, using coordinates of the points A and B.
A(1,4) and B(4,8)
|AB|=√((y2-y1)² +(x2-x1)²) =√((8-4)²+(4-1)²)=√(16+9)=√25=5

When dilating with scale factor 4,
the length of |A'B'|=4*|AB|=4*5=20

Brut [27]

Answer:

H2SO4

Explanation:

H2SO4 is actually one of the strongest acids, coming to a pH value very close to 1. Acids transfer their hydrogen ions to other substances, such as water, and usually have hydrogen in their formula. In this case, H2SO4 has hydrogen in its formula and is the acid in this case.

An electron has an uncertainty in its position of 471 pm .
olya-2409 [2.1K]

<u>Answer:</u>

$\Delta x . \Delta p \geq \frac{h}{4 \pi}$

∆x is the Uncertainty in the position of the particle

∆p is the Uncertainty in the momentum of the particle

$\Delta p=\frac{h}{4 \pi \times m \times \Delta x}$

$=\frac{6.626 \times 10^{-34} \mathrm{kgm}^{2} s^{-1}}{4 \times 3.14 \times 9.109 \times 10^{-31} \mathrm{kg} \times 471 \times 10^{-12} \mathrm{m}}$

$=\frac{6.626 \times 10^{-34} \mathrm{ms}^{-1}}{53887 \times 10^{-43}}$

=1.23\times10^5 ms^{-1} is the answer
