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.
At the equator it will be the fastest while at the pole it will be slowest
Explanation..
Because at the equator their is a long distance to be covered from the pole☝️
Answer:Temperature is directly proportional with gas , liquid and solid in its decreasing form
Explanation:So when temperature rises the the solubility of a substance also increases with it where as when it decreases it also decreases with temperature
Answer:
If you heat a gas you give the molecules more energy so they move faster.
Explanation:
I didn't understand your question at first, I believe an acceptable answer would be As and Ar.
As (arsenic) is a metalloid and Ar (argon) is a noble gas.
Hopefully I was able to help you! :)
