A student is pushing a desk across the floor of the classroom. Even though there is friction, the desk still accelerates to the right. Answer the following questions concerning the desk. The student took 90 seconds to move the desk 15 feet across the room? What was the desk's velocity? What was the desks rate of acceleration? What is the net force used by the student to move the desk?

b) phosphorus pentoxide

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

  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
