In introductory physics laboratories, a typical cavendish balance for measuring the gravitational constant g uses lead spheres with masses of 1.60 kg and 16.0 g whose centers are separated by about 4.00 cm. calculate the gravitational force between these spheres, treating each as a particle located at the center of the sphere.

Explanation:

= Gravitational constant = 6.67 x 10⁻¹¹

 = Gravitational force between these spheres

= mass of first sphere = 1.60 kg

 = mass of second sphere = 16 g = 0.016 kg

 = distance between the centers of the sphere = 4 cm = 0.04 m

Gravitational force between these spheres is given as

  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
