Answer:
The collection of all the genes and the various alternate or allelic forms of those genes within a population is called its gene pool.
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.
Answer:
86.4 N downward
Explanation:
Force: This can be defined as the product of mass and acceleration of a body.
The S.I unit of Force is Newton(N).
The Expression of force is given as,
F = ma ................ Equation 1
Where F = force of the parachute harness, m = mass of the skydiver, a = acceleration of the skydiver.
Given: m = 72 kg, a = 1.2 m/s²
Substitute into equation 1
F = 72(1.2)
F = 86.4 N down ward.
Hence the force on the parachute harness = 86.4 N downward
