a person running a car parked in a driveway
Explanation:
A person running a car parked in a driveway is an example of translational kinetic energy.
Translational motion is the movement of body along a straight path.
Translational kinetic energy refers to the energy of a body moving along a straight path.
- It is function of the mass and velocity of the moving body.
- The motion of train on its track is an example of this form of energy
- A fired bullet, falling object all experience translational kinetic energy.

Answer:carbon, hydrogen and oxygen
Explanation:
Alcohol functional group is composed of carbon, hydrogen and oxygen
Answer:
A. Dipole-dipole forces; B. dipole-dipole forces;
C. ion-dipole forces; D. ion-dipole forces
Explanation:
A. HF
HF is a weak acid but a highly polar molecule. The strongest intermolecular force with water is an especially strong dipole-dipole force (hydrogen bonding) of the type
H-F· · ·H-OH and H₂O· · ·H-F
B. CH₃OH
CH₃OH has a highly polar O-H bond. The strongest intermolecular force with water is the especially strong dipole-dipole force (hydrogen bonding):
CH₃(H)O· · ·H-OH and CH₃O-H· · ·OH₂
C. CaCl₂
CaCl₂(s) ⟶Ca²⁺(aq) + 2Cl⁻(aq)
CaCl₂ separates into hydrated ions in solution. The strongest intermolecular force with water is ion-dipole attraction.
Ca²⁺· · ·OH₂ and Cl⁻· · ·H-OH
D. FeBr₃
FeBr₃(s) ⟶Fe³⁺(aq) + 3Br⁻(aq)
FeBr₃ separates into hydrated ions in solution. The strongest intermolecular force with water is ion-dipole attraction.
Fe³⁺· · ·OH₂ and Br⁻· · ·H-OH
