If the runner ends where she started, then her total displacement is 
, which means her average velocity will be
The total distance she traversed, however, was 
, which gives her an average speed of
Answer:
B because 17100 is the half of the carbon
Answer:
Electronegative atom will create a stronger negative charge is true.
Explanation:
Given that,
Electronegativity affects the strength of intermolecular forces.
We know that,
Electronegativity :
Electronegativity is a ability of an atom, shared electron to itself.
In periodic table,
When we move left to right in period then the electronegativity increases.
When we move up to down in a group then the electronegativity decreases.
We know that,
The intermolecular forces are dipole-dipole interactions which is the strongest intermolecular force of attraction.
If the electronegativity of atom is more, then the atom gain negative charge.
When the attraction force is more in atoms then the electronegative will be more.
Hence, Electronegative atom will create a stronger negative charge is true.
Answer:
D.
Explanation: Both have shapes determined by gravitational forces.
Water freezes at zero degrees Celsius (32 degrees Fahrenheit). The solid ice particles absorb heat energy from the warmer air, giving the particles energy and enabling them to move away from one another. ... This is what happens when the ice cube (a solid) turns into water (a liquid)
