Answer:
D. What is the effect of a boat’s shape on its speed?
Explanation:
Kinetic energy can be defined as the energy possessed by an object or body due to its motion. It is the amount of work required to accelerate an object or body with a specific mass from its point of initial rest to a final velocity.
Mathematically, kinetic energy (K.E) is equal to 1/2(mv²).
Hence, the question which would involve the investigation of kinetic energy is "what is the effect of a boat’s shape on its speed?" because speed is directly related to the motion of the boat. Generally, the shape of the hull of a boat has an effect on the speed of the boat.

Answer: The Answer is minus 221kj.
Explanation: Solved in the attached picture.
Covalent bonds are formed when 2 neutral atoms come together to share a pair of electrons, where each atom contributes one electron each to be shared.
The covalent bond is kept together by the electrostatic attraction between the nuclei of the atoms and the shared pair of electrons.
Covalent bonds are usually formed between non metals with a small difference in their electro negativity.
the correct answer is
A. Neutral atoms coming together to share electrons
The answer is b: in the oscillating electric and magnetic fields
