Definición como rama de la física y su campo de estudio.
taurus [48]

Answer:

Ver la explicacion abajo.

Explanation:

La física es una ciencia exacta que explica las propiedades de la materia y de la energía, por medio de leyes y ecuaciones explica los fenómenos naturales que suceden a nivel microscópico y macroscópico. La física se puede dividir en estudios de la mecánica clásica y de la mecánica cuántica.

<u />

<u>Mecanica clasica</u>

<u />

Se ocupa de los fenomenos fisicos que suceden a nivel macroscopico, donde se pueden aplicar las leyes de Newton para explicar los diferentes fenomenos que suceden a nivel universal. Esto sucede a velocidades mucho menores comparadas a la velocidad de la luz.

<u>Mecanica cuantica.</u>

<u />

Estudia sistemas de pequeña escala, como atomos y particulas elementales.

<u />

<u>Mecanica Relativista</u>

<u />

Describe comportamiento de cuerpos que se mueven con velocidades cercanas a la velocidad de la luz. A partir de ahi no se pueden utilizar las mismas ecuaciones de la mecanica clasica para describir los comportamientos fisicos de los cuerpos.

A proton circulates in a cyclotron, beginning approximately at rest at the center. Whenever it passes through the gap between de
nevsk [136]

Answer:

(a) 120 eV

(b) 12.840 keV

(c) 0.466%

Solution:

As per the question:

The potential difference between the dees, V = 120 V

No. of passes, n = 107

Now,

(a) The potential energy can be given as 'qV' but by the principle of conservation of energy, this energy with each pass is converted into the kinetic energy of the particle which is given as 120 eV

Thus

The increase in Kinetic energy, \Delta KE = 120\ eV

(b) Kinetic energy on completion of 107 passes is given by:

KE = n\Delta KE = 107\times 120\ eV = 12.840\ keV

(c) The velocity of the particle can be calculated from its kinetic energy:

KE = \frac{1}{2}m_{p}v^{2} = 12.840\ keV = 120n\ eV

Thus

v = \sqrt{\frac{240ne}{m_{p}}}

Thus radius can be given as:

R = \frac{m_{p}}{Bq}(\sqrt{\frac{240ne}{m_{p}}})

where

B = Magnetic field

m_{p} = mass of proton

Therefore, we can write that:

R = \sqrt{n}

Thus the percentage increase in radius from n = 107 to n = 108 is given by:

\Delta R(in\ percent) = \frac{\sqrt{108} - \sqrt{107}}{\sqrt{107}}\times 100 = = 0.466 %

A bicycle rides in a straight line at 1 km at 10
ahrayia [7]

Answer:

avg speed =total distance/total time

total distance =2km (given)

total time=1/10 +1/25=7/50

so avg speed =100/7=14.28
