Answer:
External force on him = 257.40 N
Equation is; F = ma (where 'f' is force, 'm' is mass and 'a' is acceleration)
Explanation:
The mass of the sprinter is 58.5 kg
His acceleration is 4.40 m/s²
According to Newton's second law of motion; F = ma
External force on the sprinter = 58.5 kg × 4.40 m/s² = 257.40 N
Answer:
y=8
Explanation:
every time you multiply x by 3 you divide y by 3.
x=2, multiply it by 3: x=6
y=24, divide it by 3: y=8
Answer:
Induced
Permanent
Transient
Explanation:
Induced: occurs when a molecule that has a permanent dipole repels another one's molecule's electrons, inducing the one that has a dipole moment in that molecule.
Permanent: occurs when two atoms in a molecule possess a substantially different electronegativity. i.e one atom attracts electrons more than another atom and males it more negative, while the other atom turns more positive.
Transient dipole: induces a dipole in the neighbouring molecule, and then interacts with the original transient dipole.
