1 kg = 1000g
2.43 kg *1000g/1kg = 2430 g
The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct did not give the results described and is denoted as option A.
<h3>What is Thomson “plum-pudding” model?</h3>
This model was proposed by J.J Thomson in which referred an atom as a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.
This model was incorrect and the Rutherford atomic model was adopted in which he described the electrons orbits about a tiny positive nucleus.
The nucleus contains protons and neutrons instead thereby making it the correct choice.

The options include the following:
a.The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct.
b.The Rutherford experiment was useful in determining the nuclear charge on the atom.
c.Milikan’s oil-drop experiment showed that the charge on any particle was a simple multiple of the charge on the electron.
d.The electric discharge tube proved that electrons have a negative charge
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart
