By Angle Addition Postulate,

\(JL=JK+KL\)

Substitute given expressions:

\(2x+8=(2x−2)+(x−9)\)

Solve for x:

\(2x+8=3x−11\)

\(−x+8=−11\)

\(−x=−19\)

\(x=19\)

Hence,

\(KL=19−9\)

\(KL=10\)

Two stationary point charges +3 nC and + 2nC are separated bya distance of 50cm. An electron is released from rest at a pointmidway between the two charges and moves along the line connectingthe two charges. What is the speed of the electron when it is 10cmfrom +3nC charge?

Besides the hints I'd like to ask you to give me numericalsolution so I can verify my answer later on. It would be nice ifyou could write it out, but a numerical anser would be fine alongwith the hint how to get there.

For digits before decimals point, multiply each digit with the positive powers of ten where power is equal to the position of digit counted from left to right starting from 0.

For digits after decimals point, multiply each digit with the negative powers of ten where power is equal to the position of digit counted from right to left starting from 1.

1) \(10^{0}=1\)

2) \(10^{1}=10\)

3) \(10^{2}=100\)

4) \(10^{3}=1000\)

5) \(10^{4}=10000\)

And so on...

6) \(10^{-1}=0.1\)

7) \(10^{-2}=0.01\)

8) \(10^{-3}=0.001\)

As depicted in the applet, Albertine finds herself in a very odd contraption. She sits in a reclining chair, in front of a large, compressed spring. The spring is compressed 5.00 m from its equilibrium position, and a glass sits 19.8m from her outstretched foot.

a)Assuming that Albertine's mass is 60.0kg , what is \(\displaystyle\mu_{{k}}\), the coefficient of kinetic friction between the chair and the waxed floor? Use \(\displaystyle{g}={9.80}\frac{{m}}{{s}^{{2}}}\) for the magnitude of the acceleration due to gravity. Assume that the value of k found in Part A has three significant figures. Note that if you did not assume that k has three significant figures, it would be impossible to get three significant figures for \(\displaystyle\mu_{{k}}\), since the length scale along the bottom of the applet does not allow you to measure distances to that accuracy with different values of k.
