Disk a, with a mass of 2.0kg and a radius of 80cm , rotates clockwise about a frictionless vertical axle at 20rev/s . disk b, also 2.0kg but with a radius of 30cm , rotates counterclockwise about that same axle, but at a greater height than disk a, at 20rev/s . disk b slides down the axle until it lands on top of disk a, after which they rotate together. part a after collision, what is their common angular speed (in rev/s)? part b and in which direction do they rotate? a) clockwise b) counterclockwise

  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

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
