Please answer correctly I need the answer now

Problem 1 ;

m = 3.5 kg

a = 2.2 m/s²

F = m a

F = 3.5 × 2.2

F = 7.7 kg m/s²

F = 7.7 N

___o___o___

Problem 2 ;

m = 3 kg

a = 2 m/s²

g = 9.8 m/s²

W = m g = ( 3 kg ) ( 9.8 m/s² ) = 29.4 kg m/s² = 29.4 N

T – W = m a

T – 29.4 = 3 × 2

T – 29.4 = 6

T = 6 + 29.4

T = 35.4 N

I hope I helped you^_^

explanation:

could i give you a exaplo that could you?

  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
