Friction is the motion of one moving object relative to another
Answer:
The correct answer is option b. "He passed cathode rays through a magnetic field and measured the deflection".
Explanation:
J. J. Thomson was a notorious scientist that did not only made the discovery of the electron, but he measure its charge to mass ratio. In order to determine this property, Thomson passed cathode rays through a magnetic field and measured the deflection. Cathode rays are actually composed of particles, which are now known as electrons, and its charge to mass ratio is about 10^8 coulomb per gram.
Answer:
1. Students need to measure masses of the items.
2. Put baking soda and vinegar in a plastic bag and close it.
3. Mix the two, allowing for a reaction to occur.
4. Figure the mass of the plastic bag while the two components are inside.
5. The combined mass should be equal to what each weighed on their own.

Answer: The process is diffusion.
Explanation:
a dark liquid will have the highest concentration of dark purple atoms/molecules so it gives a concentrated colour.
when water is added to it, the colourless water molecules fill up the gaps between the purple particles and so their colour fades and becomes lighter and lighter as we add more water. see the image attached where imagine the red particles are water and the blue particles are purple particles. thats why the colour fades.
