<span>2).Cathode rays have mass. </span><span>3).Matter contains positive and negative charge. </span>5).Particles of the cathode rays are fundamental to all matter. 6).An atom is divisible.
The answer is B. She can measure the mass of the water, marble and the graduated cylinder with the balance. The volume of the water can be shown on the marked graduated cylinder, the volume of the marble can be measured by the volume difference of the water before and after the marble is put in.
