Answer:
x_{cm} = 4.644 10⁶ m
Explanation:
The center of mass is given by the equation
= 1 / 
∑ 
Where M_{total} is the total masses of the system, 
is the distance between the particles and 
is the masses of each body
Let's apply this equation to our problem
M = Me + m
M = 5.98 10²⁴ + 7.36 10²²
M = 605.36 10²² kg
Let's locate a reference system located in the center of the Earth
Let's calculate
x_{cm} = 1 / 605.36 10²² [Me 0 + 7.36 10²² 3.82 10⁸]
x_{cm} = 4.644 10⁶ m
To solve for distance use the formula for distance d = st, or distance equals speed times time.
distance = speed x timeSpeed
so the answer is 240 miles per hour.
Explanation:
<h3>Electricity is defined as the rate of flow of charges in a conductor.</h3>
<h2>hope it helps.</h2><h2>stay safe healthy and happy...</h2>
Distance= speed * time
So multiply speed and time to get the value of distance
20*9.8 =196 meters
The charge of an atom before any electrons are transferred is zero.An atom as a whole is electrically neutral.
An atoms contains same number of electrons and protons. The charge of an electron and a proton is equal in magnitude but opposite in sign. The charge of a proton is 1.6 x 10⁻¹⁹C and the charge of an electron is -1.6 x 10⁻¹⁹C .Thus the charge of all the protons in an atoms is neutralized by the total charge of all the electrons.Thus an atom is electrically neutral.
when an atom loses electrons , it acquires a positive charge and when it gains electrons, it acquires a net charge.
