Why did thomson’s results from experimenting with cathode rays cause a big change in scientific thought about atoms?
natima [27]

Answer:

Explanation:

Before Thomson's discovery, atoms were believed according to the "Dalton's atomic theory" to be the smallest indivisible particle of any matter. This makes atoms the smallest unit of a matter.

Thomson in 1897, used the discharge tube to discover cathode rays which are today called electrons.

The discovery of electrons provided more light into the structure and nature of atoms. Atoms were now being seen in a different light as particles that are made up of other smaller sized particles.

Thomson through his experiment was able determine perfectly well the nature of the rays he saw emanating from the cathode. One of his findings shows that the rays are negatively charged and are repelled by negative charges.

The discovery of electrons further led to more works on the atom and other particles were discovered. Atoms were no longer seen as indivisible or the smallest particles of matter.

Explain how an object can have force acting on it but not be acceleration?
VladimirAG [237]

That's what happens if there is more than one force acting on the
object, and the forces are balanced, that is, they all "cancel out".

Think of the rope in a Tug-'o-War.  It has 50 musclebound football guys
all pulling the rope to the west, and 150 strong cheerleaders all pulling
the rope to the east.  The total force to the west is exactly equal to the
total force to the east, and the rope doesn't move at all.  The forces on it
are balanced, and the effect on its motion is the same as if there were  
no force on it at all.
