Answer:

What were experiences in his life that led to his interest in science and the study of the atom? (3-5 sentences paraphrased)

= James Chadwick was a physicist who was awarded a Nobel Prize in physics for his discovery of the neutron.

Defend his work on the atom and its contribution to the modern atomic model. (3-5 sentences paraphrased)

= Neutrons are located in the middle of an atom, in the nucleus along with protons.

Point out which contributions are present in the modern atomic model and which were eventually disproven and thus are not part of the modern model. (3-5 sentences paraphrased)

= The Protons, and the electrons are the outer layer of the atom and the neutron, and the nucleus are in the center of the atom.

En un m.A.S. La amplitud tiene un valor de 10 centimetros y el periodo es de 2 segundos calcular el valor de la velocidad de 0.8
Ivanshal [37]

Answer:

v1=18.46m/s

v2=29.8cm/s

Explanation:

We know that

A=10cm\\T=2s

the equation of the motion is

x=Acos(\omega t)\\

we can calculate w by using

\omega=\frac{2\pi}{T}=\frac{2\pi}{2}=\pi

Hence, we have that

x=10cm*cos(\pi t)\\

the speed will be

v=-\omega*Asin(\omega t)\\|v(0.8)|=|\pi*10cm*sin(\pi *0.8)|=18.46\frac{cm}{s}\\|v(1.4)|=|\pi*10cm*sin(\pi *1.4)|=29.8\frac{cm}{s}

hope this helps!
