An object will not move if:
A.) All forces acting on it are balanced.
This can be proved by example, while similtaneously proving the other answers wrong.
Take for example;
Two people are pushing on a box with 30N, one person being on the right, the other being on the left.
The opposing forces are exerting against eachother, creating a stable position on the box.
How about "if there was no gravity on it"?
Take for example an airplane. Turbulence effects the plane even when it's defying gravity.
The next two are easy to debunk.
"It's mass increases"
This can be disproved by anything.
If I were to become bigger, I'm not moving, my body is just extending in size.
This also applies to weight.
The answer is A.)
I hope this helps!
Answer:
Ernest Z. The molarity and mass percent of the vinegar are 0.8393 mol/L and 5.010 %.
Increasing temperatures in a reaction increases the kinetic energy of the reactant molecules. This causes them to move fast and hence collide with a higher frequency. The higher the rate of collision between the molecules, the faster the reaction.
Explanation:
Thomson model compared the structure of the atom with a watermelon in which the red portion signifies the positive charge and the electrons which are negatively charged are embedded in this portion as seeds are embedded in the watermelon.
<u>The structure was not able to explain the stability of the atom and also the Rutherford experiment which is:</u>
Rutherford conducted an experiment in which he took a thin gold particle film on which he passes alpha- particles. He noticed that:
- Most of the alpha particles get through the film and can be detected by the detector.
- Around small portion of the alpha particle deflected at small angles.
- A very very few alpha particle (approximately 1 out of 1 million alpha particles) just retraced their path which means come back from the center.
He concluded that:
Most of space of atom is empty and in center of atom , there is solid mass which is cause of alpha particles to come back. He gave term nucleus to this solid mass.
