What is the mass of the second particle : A magnifier has a magnification of 8 times. How far from the lens should an object be placed so that its (virtual) image is at the near-point distance of 25 {rm cm}. |

Compute the x-component of this vector : A car travelling at 25.0 m/s runs out of gas while travelling up a 33.0 degree slope. How far up the hill would it coast before starting to roll back down. |

What is electric field strength : Oxygen (O2) gas within a piston-cylinder assembly undergoes an expansion from a volume V1= 0.02 m3 to volume V2 = 0.03 m3. The relationship between pressure and volume throughout the procedure is p=AV-1+B, where A= 0.06 bar.m3 and B= 3.0 bar. For the.. |
