Find what is the ratio of the internal energy of hydrogen UB. To the internal energy of helium UJ for two moles of hydrogen and

four moles of helium taken at the same temperature
Physics
1 answer:
finlep [7]3 years ago

Answer:

Ration of internal energy of hydrogen to the internal energy of helium is equal to \frac{5}{6}

Explanation:

As we know

degree of freedom of hydrogen is 5

Degree of freedom of helium is 3

Internal energy of hydrogen

\frac{5}{2} * 2 * RT = 5 *RT

Internal energy of helium

\frac{3}{2} * 4 * RT = 6 *RT

Ration of internal energy of hydrogen to the internal energy of helium is equal to \frac{5}{6}

While Robert was helping his father in the garden, he pushed a shovel into the ground to dig a hole in the dirt. He picked up a
makvit [3.9K]

Work done is given by the change in kinetic energy of an object

  • The kinetic energy of the shovel, the shrub, and in Robert's movement were changed, therefore, work is done in the given processes,

Reason:

Work is done when the total energy of object is affected by the application of force on the object over a distance

Therefore;

  • In option <em>A</em>, pushing the shovel into ground (to dig out the dirt) the requires the application of a force (push) over a distance, (into and out of the ground) therefore work is done
  • In option <em>B</em>, picking the shrub up gives it gravitational potential energy, therefore, work is done
  • In option <em>C</em>, carrying the shrub to the hole does visible work
  • In option <em>D</em>, holding the shrub while lowering it into the hole does work by preventing the shrub from falling randomly

Therefore, <u>work is done in the given processes</u>

Find the kinetic energy ofan electron that moves at half the speed of light to four significant digits.
Vlad1618 [11]

Answer:

Ke=electron kinetic energy=10.24*10^{33} J

Explanation:

The electron has a mass of 9.1*10^{-31} kg

The speed of light in a vacuum is a universal constant with the value 299 792 458 m / s (186 282,397 miles / s), although it is usually close to 3*10^{8} \frac{m}{s}

Kinetic energy (K) is the energy associated with bodies that are in motion, depends on the mass and speed of the body and is calculated using the formula:

K=\frac{1}{2} *m*v^{2}        Equation(1)

K=kinetic energy (J)

m =mass of the body (kg)

v= speed of the body(\frac{m}{s} )

for this problem We replace in the equation (1)

me=9.1*10^{-31} kg = electron mass

ve=1.5*10^{8} \frac{m}{s}=Half the speed of light

=electron speed

We replace in  the  equation (1) :

Ke=\frac{1}{2}*me*ve^{2}

Ke=\frac{1}{2} *9.1*10^{-31} *(1.5*10^{8} )^{2}

Ke=4.55*10^{-31} *(1.5)^{2} *(10^{8} )^{2}

Ke=10.24*10^{33} J

The energy kinetic of the electron is 10.24*10^{33} Joules
