Answer:

The B Major chord, which forms the root of the B scale, is made up of the notes B, D#, and F#— the first, third, and fifth notes of the key of B. On the guitar, using the basic B chord position shown in the picture, these notes arrive in this order: Mute, B, F#, B, D#, and F#

if you dropped a ball while standing on the surface of mars at what rate would it accelerate toward the ground

Inessa05 [86]

First of all you need to have in mind the following data:
Mass of Mars: 6.43 x 10^23 kg
Radius of Mars: 3.40 x 10^6 m
Formulas: F = G(m1)(m2)/(r^2), m1 = F(r^2)/G(m2), m2 = F(r^2)/G(m1), F = ma G = 6.67 x 10^-11
 We can say that the first and second objects with mass can be called as following:
m1= centre of Mars
m2 = will be the ball.
The distance between them = the radious of mars.

Water has a mass per mole of 18.0 g/mol, and each water mo- lecule (H2O) has 10 electrons. (a) How many electrons are there in o

Dovator [93]

Answer:

a) There are $3,35*10^{26}$ electrons in a liter of water.

b) The net charge is -53601707,1 C

Explanation:

a) To find out how many electrons are in a liter of water (equivalent to 1000 grams of water), we have to find out how many molecules of water there are and then multiply it by 10 (e- per molecule).

We can find out how many molecules are by finding the number of moles and then multiplying it by Avogadro's number (number of elements per mol):

$e^{-}= \frac{m_{water} }{M_{water} } * Avogadro* \frac{e^{-} }{molecule}= \frac{1000g }{18g/mol} * 6,022*10^{23} * \frac{10e^{-} }{molecule}=3,35*10^{26} e^{-}$

b) As all electrons have the same charge, in order to find the net charge of those electrons we have to multiply the charge of a single electron by the number of electrons:

$Net charge= -1,602*10^{-19} \frac{C}{e^{-} } *3,35*10^{26} e^{-}=-53601707,1 C$

An important clarification is that while the net charge may seem huge, water as a whole is a neutral medium, because there are as many protons as there are electrons, and as they have the same charge, the net charge of water is 0.
