Biotic is the living factors while abiotic is nonliving such as a rock
Explanation:
The position vector r:

The velocity vector v:

The acceleration vector a:



Answer:
angular velocity(ω) is the rate change of angular displacement.
ω=θ/t and it SI unit is rad/s
Explanation:
this is very similar with the definition of linear velocity (rate of change of displacement). it specifies the angular speed of an object and the axis about which the object is rotating.
Answer:
It takes total 248 years for Pluto to orbit the sun.
Ignoring air resistance . . .
-- Gravity adds 9.8 m/s to the speed of a falling object every second.
-- After falling for 3 sec, it's falling (3 x 9.8) = 29.4 m/s faster
than it was when it was dropped.
-- It started out with zero speed when it rolled off the top of the building,
so its speed is 29.4 m/s after 3 seconds.
-- Its average speed all the way down is
(1/2) (0 + 29.4) = 14.7 m/s .
-- After traveling for 3 sec at an average speed of 14.7 m/s,
it has traveled
(3 sec) x (14.7 m/s) = 44.1 meters .
