What is the third step of the hydrogen fusion process?
o
h+h - {h+ e* + v + energy
he + he – he +2 (1h) + energy
o ? h+ 1h – he + energy
6(1h) + 2(-e) - he + 2(1h) + energy + 2v

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

The slope of a velocity time graph over any interval of time gives the during that interval

Considering only the earth's rotation, determine how much later the asteroid would have had to arrive to put the explosion above helsinki at longitude 25˚ e? this would have obliterated the city.
