Answer:

Explained

Explanation:

Through Rutherford's gold foil experiment, he disproved J.J Thompson's theory. Rutherford was very interested in studying the behavior of x-rays, which was then recently discovered by Curie. When he shot a beam of alpha particles (particles with 2 neutrons and 2 protons, or the Helium atom) toward the gold foil, the particles were deflected by a slight angle. He then theorized that these deflections were due to the existence of a dense nucleus inside the atom.

Following Rutherford's discovery of the nucleus, Niels Bohr theorized the planetary model of the atomic structure. According to him, the atom is like a solar system wherein the Sun is the nucleus and the planets are the electrons orbiting around it. The electrons and protons move this way because they are influenced by an electric force due to the difference of their charges.

Answer:

$q=3.19*10^{-8}C$

Explanation:

The expression for the electric force between two charges

$F=k\frac{q_1q_2}{r^2}\\$

where K is the Coulomb's constant (k=9*10^{9}Nm^2/C^2), and we have that

q1=q

q2=3q

r=3.39m

F=2.4*10^{-6}N

By replacing in the formula we have

$F=2.4*10^{-6}N=(9*10^{9}\frac{Nm^2}{C^2})\frac{(q)(3q)}{(3.39m)^2}\\\\$

and by taking apart q we have

$q=3.19*10^{-8}C$

hope this helps!!

Which of the following will cause an increase in the mass of an object? (1 point)

kompoz [17]

You can’t increase the gravitational pull without the use of mass or energy itself. So both answers talking about gravity is incorrect. C is the obvious choice here. If you increase the amount of matter in an object, the mass will increase

<h3>Answer:a) Distance= 240m. b) Displacement= 90m. c) Average Speed= 5 $ms^{-1}$ . d) Average Velocity= 1.875 $ms^{-1}$ </h3>

Explanation:

a) Distance ➤ (80+50+70+40) m. ➤ Distance= 240m.

b) Displacement ➤ (50+40)m. ➤ Displacement= 90m

c) Average Speed ➤ Total distance travelled/total time taken

➤ 240/48

➤ 5 $ms^{-1}$

d) Average Velocity ➤ Total displacement/total time taken

➤ 90/48

➤ 1.875 $ms^{-1}$

____________are necessary to explain research findings.

Elodia [21]

Answer:

C. Theories

Explanation:

Theories basically explain why of research findings. By definition, theories help us understand, explain, and predict the occurrence of a phenomena. In research, theories support research findings by explaining how the variables involved influence each other not merely based on observation during this one experiment. It also helps validate the findings by relating it to theories of previous work.
