You knew that this question is ridiculously easy. So, just to
make it harder, you decided not to let us see the picture, so
that we could not "examine the circuit".
The description is talking about a parallel circuit. The other
kind is a series circuit, and that one has no forks in the road.
Answer:
1.176 N
Explanation:
= mass of the bottle = 0.30 kg
= initial speed of the bottle = 2.8 m/s
= final speed of the bottle = 0 m/s
= stopping distance traveled = 1.0 m
= magnitude of frictional force acting on bottle
Using work-change in kinetic energy theorem
N
direction :
frictional force acts in opposite direction of motion.
The question to the above information is;
What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?
Answer;
An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
Explanation;
-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.
J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:
- atoms are spheres of positive charge
- electrons are dotted around inside
Mendeleev produced the first orderly arrangement of known elements.
Mendeleev used patterns to predict undiscovered elements.
