Velocity is about direction traveled in comparison to speed which is just distance with out direction
To solve this problem we will apply the concept related to the kinetic energy theorem. Said theorem states that the work done by the net force (sum of all forces) applied to a particle is equal to the change experienced by the kinetic energy of that particle. This is:


Here,
m = mass
v = Velocity
Our values are given as,


Replacing,


Therefore the mechanical energy lost due to friction acting on the runner is 907J
Answer:
I think its C, even with the typo.
Magnesium is in group 2 while sulfur is in group 6.
the group number determines the number of valence electrons.
Metals gives lose electrons (mg)
Non Metals gain electrons (s)
answer: Magnesium gives 2 electrons to sulfur.
Mg is now 2.8
Sulfur is 2.8.8
cuz ionic bonding
