Emanuel Zacchini, the famous human cannonball of the Ringling Bros. and Barnum and Bailey Circus, was fired out of a cannon with a speed of 24.0 m/s at an angle of 40.0 degrees to the horizontal. If he landed in a net that 56.6 m away at the same height from which he was fired, how long was Zacchini in the air?

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures

there are no atoms
