The Ballistic Pendulum Crime Lab Physics You are a criminologist‚ and have been given a gun which has been used in the commission of a crime. Both prosecution and defense claim that "muzzle velocity" (speed of the bullet as it leaves the gun) is crucial to the case. Your job...FIND IT! Shown below is a diagram representing a "ballistic pendulum." The bullet is fired into the block‚ the bullet-block combination rises by a height h as shown‚ a little physics is applied‚ and ...voila!...there

8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between

(RD) or specific gravity (SG) is a dimensionless quantity‚ as it is the ratio of either densities or weights. The principle used in this experiment was the Archimedes ’ Principle. Archimedes ’ principle is named after Archimedes of Syracuse‚ who first discovered this law in 212 B.C‚ he stated that: “Any object‚ wholly or partially immersed in a fluid‚ is buoyed up by a force equal to the weight of the fluid displaced by the object.” It is stated in the principle that objects weigh more in air than
