Amover pushes a 255 kg piano
with a 77.5 n force to the left, while
a second mover pulls the piano
48.7 n to the left. what is the
acceleration of the piano?
(watch your minus signs.)
(unit = m/s)

Explanation:

According to the newton's second law of motion we can apply F=ma hear

Force = mass * acceleration

(assume the piano is moving left side )

←F = ma

  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
