Due today help 16. On the moon, Bob weighs 160 N while on earth Fred weighs 882 N. Who has the greater mass?

17. A 4 kg mass sits on a table that has 5 N of friction. If Maria applies a 25 N force to the mass, how fast will it accelerate?

18. How much force is required to accelerate an 8 kg mass at 5 m/s2 if there is 14 N of friction?

c. magnitude and direction

  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

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
