When the potential energy is lowest, what is true of the kinetic energy?

The kinetic energy is larger than or equal to the kinetic energy

Explanation:

The total mechanical energy in a body is made of the sum of the potential and kinetic energy of the body as such, given that the total mechanical energy of the body remains constant, as the potential energy reduces, the kinetic energy of the body increases.

For example, an object at an elevated point as a high potential energy and 0 kinetic energy as the object falls, the potential energy is converted to kinetic energy and the and the speed of the object increases. The kinetic energy is highest just before the object touches the ground, at which point the potential energy is lowest

Therefore, when the potential energy is lowest, the kinetic energy is either equal to (for objects at rest state) or larger than (for momentary dynamic systems) than the potential energy.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
