Answer:
Newton's third law explains the generation of thrust by a rocket engine. In a rocket engine, hot exhaust gas is produced through the combustion of a fuel with an oxidizer. The hot exhaust gas flows through the rocket nozzle and is accelerated to the rear of the rocket. In re-action, a thrusting force is produced on the engine mount.

Answer:
2.38732 rpm
1.22625 rad/s²
163.292°
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration = 
d = Diameter of wheel = 2 m
r = Radius of wheel = 
v = Speed of elevator = 25 cm/s
Angular speed is given by
The angular speed of the wheel is 2.38732 rpm
Angular acceleration is given by
The angular acceleration of the wheel is 1.22625 rad/s²
Angular displacement is given by
The angle the disk turned when it has raised the elevator is 163.292°

Explanation:
The pull strength is the highest possible holding power of a magnet, measured in kilograms. It is the force required to prise a magnet away from a flat steel surface when the magnet and metal have full and direct surface-to-surface contact.
Answer: stretch when your muscles are already warm
don't rush through a stretching routine.
slowly ease into position and hold stretch smoothly in order to adequately release tension
breath normally through stretch
stretch each major muscle group together in full range of motion
Explanation: warmth provides stretch with east, cold stretching causes more strain and possible injury
oxygen is delivered to the muscles during proper breathing technique
