Which of the questions would involve the investigation of kinetic energy? A. What material makes the strongest boat?

B. How does the color of a boat affect heat absorption?

C. Do boats float higher in salt or fresh water?

D. What is the effect of a boat’s shape on its speed?

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.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
