Buhrs atomic model differed from ruthofords because it explained that electrons exist in specified energy levels surrounding the nucleus. This means that, Ruthoford believed that electrons can't do very much. However, Buhrs' model showed that electrons are much more powerful than anyone else believes they can be.

Answer:

Explanation:

Rutherford's model shows most of an atom mass is in the middle with a positive charge while the negatively charged electrons are outside in a cloud. Bohr improved on his model and explained that the electrons move in certain orbits around the central mass (called the nucleus.)

The fact that the magnetic field generates a force perpendicular to the instantaneous velocity of the particle has implications
Anna35 [415]

Answer:

<h2>c. remain constant</h2>

Explanation:

Such type of field that is created by the magnetic condition is known as magnetic field. Such type of the developed by electrical condition and some other ways. This filed has many important roles in electrical engineering and some other fields.  

When any magnetic field acts in perpendicular condition then no work is done by the field. Thus the kinetic energy and speed of the particle remain in constant condition.

Why is it important to know the center of gravity of an object?
Blizzard [7]

Explanation:

The direction of the force of gravity through the body is downward, towards the centre of the earth and through the COG. This line of gravity is important to understand and visualise when determining a person's ability to successfully maintain Balance.

For fully developed laminar pipe flow in a circular pipe, the velocity profile is u(r) = 2(1-r2 /R2 ) in m/s, where R is the inn
sdas [7]

Answer:

a) v_{max} = 2\ \textup{m/s}

b) v_{avg} = 1\ \textup{m/s}

c) Q = 1.256 × 10⁻³ m³/s

Explanation:

Given:

The velocity profile as:

u(r) = 2(1-\frac{r^2}{R^2} )

Now, the maximum velocity of the flow is obtained at the center of the pipe

i.e r = 0

thus,

v_{max}=u(0) = 2(1-\frac{0^2}{R^2} )

or

v_{max} = 2\ \textup{m/s}

Now,

v_{avg} = \frac{v_{max}}{2}\ \textup{m/s}

or

v_{avg} = \frac{2}}{2}\ \textup{m/s}

or

v_{avg} = 1\ \textup{m/s}

Now, the flow rate is given as:

Q = Area of cross-section of pipe × v_{avg}

or

Q = \frac{\pi D^2}{4}\times v_{avg}

or

Q = \frac{\pi 0.04^2}{4}\times 1

or

Q = 1.256 × 10⁻³ m³/s
