Temperature is a measurement of the average kinetic energy of an object’s molecules
Answer:
D. 12.5 min
Explanation:
Speed = distance ÷ time.
time = distance ÷ speed.
18km × 1000m = 18000m (as speed is in m/s).
time = 18000m ÷ 24.0m/s
t = 750s.
750s ÷ 60
= 12.5mins is your answer.
hope this helps. :)
Centripital force is a force that draws an object toward a center point. Think of gravity acting on a celestial object as it revolves around the sun, or the force that a string exerts on a ball tied at the end of it to keep it from flying away.
Inertia is the forward momentum of an object, the tendency of an object to continue moving in the direction it is already moving in.
Intertia and centripital motion combine to create circular motion, as an object that is moving in some direction away from a center object, but still drawn to that object by a centripital force, will continue to move, at the same distance away from the object, in a circle around it.
Organisms overproduce offspring, so only some survive and pass on their traits.
Natural selection is the fitting of a population to its environment.
Explanation:
Most organisms produce more than two or more offspring in their lifetime. Therefore the subsequent generations ideally have more individuals than the previous. However, naturally, the population size does not grow indefinitely. This is because some individuals do not survive to pass their genes to the next generation. Natural selection chooses the best fit individuals to habitat, and these live long enough to pass their traits to the next generation. Natural selection powers the evolution of a population even as environment changes
