Explanation:

Hello ! Let's solve this!

1-atomic number: the atomic number is the number of protons that the atom has

2-mass number: is the amount of protons plus the amount of neutrons in the atom

3-atomic weight: average of the masses of an atom per 1/12 of the mass of carbon

4-isotope: it is the same element that has the same number of protons but a different number of neutrons

5-natural abundance: measures the amount of isotopes of an element in nature

6-unit of atomic mass: (uma) is a unit that is equivalent to 1/12 of the carbon atom

Help with either I don’t understand this I know W=f*d but don’t get how it applies here
rosijanka [135]

Answer:

5) Displacement = +3.125 m

Displacement is in the same direction as the force vector.

6) Force = -53.89 N

Force is in an opposite direction relative to the displacement.

Explanation:

5) We are given;

Force; F = 160 N.

Workdone; W = +500 J

Now, formula for workdone is;

W = Force × displacement

Thus, displacement = Work/force

Displacement = 500/160

Displacement = +3.125 m

Thus, displacement is in the same direction as the force vector.

6) We are given;

Displacement; d = 18 m.

Workdone; W = -970 J

Like in the first answer above,

Workdone = Force × Displacement

Thus;

Force = Workdone/Displacement

Force = -970/18

Force = -53.89 N

Since force is negative and displacement is positive, it means force is in an opposite direction relative to the displacement.
