The best method to use in prevention of self-demagnetization of a permanent magnet is by use of a keeper. Keepers were also commonly known as amateurs. They help in storing magnets safely, especially those that have low coercivity ( magnets that are extremely susceptible to stray fields).

His knees are flat in front of him or 180 degrees, i hope that answered your question
According to the trichromatic theory of color vision, also known as the Young-Helmholtz theory of color vision, there are three receptors in the retina that are responsible for the perception of color. One receptor is sensitive to the color green, another to the color blue and a third to the color red.
Hope this helps.
False, Carbon usually forms four covalent bonds.
Answer:
Using the RC discharge and recharge table it means that after 5 time constant s there is a maximum current of 99.3% and a maximum voltage of 0.7% while form the charge table there will be a maximum voltage of 99.3% and maximum voltage of 0.7% in the RC CIRCUIT USIng
Vc/Vs= e^ -t/z for discharge and
Vc/Vs = e^(1-t/z) for charging
