There are two qualities that can describe most variables - direction and magnitude. A vector possesses both a direction and magnitude, while a scalar possesses only a magnitude.
Hope this helps!
You can accelerate by changing direction, even though you don't speed up/down. Remember that acceleration is a vector so, it has a direction and a magnitude. That's why this works! Hope it helps.
Answer:100 meters per min
Explanation:
Answer:
Explanation:
Each time the work done to raise a given mass is
here we know that
now we have
since it is just 25% of actual energy consumed as we know its efficiency is 25%
so we have total energy consumed in this way
now if it took N number of times so burn the fat of a pizza then
The electron cloud is split up in 3 areas.
1) Inner Electron Cloud
2) Outer Electron Cloud
3) Valence Electrons
Your inner cloud is the electrons CLOSEST to the nucleus.
Your outer cloud is the electrons in the MIDDLE of the Inner and Valence.
Your valence electrons are the OUTER LAYER of electrons. These electrons are important to bonding, and also are what decide where on the periodic table of elements. For example:
197
Au
79
This element is GOLD. It has 1 valence, therefor it is where it is in the period. Ionization could change this number however.
