I think it’s when the sun explodes because since we need to the sun I think the human population will fall out. also a huge war, a meteoroid huge as the one that killed the dinosaurs comes down, there is so much ways on how the human population can stop growing. hope this help at least!
Answer: After acceleration the iron nuclei travel at a steady speed of one-tenth of the speed of light .the speed of light is 3.00 x 10^8. calculate ...
Explanation:
True, because people should reach their full potential within themselves and human psychologist should help those that need help to reach it.
its c because The microscopically colliding particles, that include molecules, atoms and electrons, transfer disorganized microscopic kinetic and potential energy, jointly known as internal energy.
Answer
given,
height = 300 m
speed of aircraft = 40 m/s
propeller rotation = 20 rev/s
moment of inertia = I = 70 Kg/m²
mass = 200 Kg
since no non conservative force act on system, the mechanical energy is conserved after propeller fall off.
by conservation of energy
as there is no air resistance ωi = ωf
b) the rotation rate of the propeller remains same as there is no air resistance.
