Describe the main distinguishing features of spiral, elliptical, and irregular galaxies.
hram777 [196]

Answer:

Spiral galaxies consist of a flat, rotating disk of stars, gas and dust, and a central concentration of stars known as the bulge. These are surrounded by a much fainter halo of stars, many of which reside in globular clusters.

Elliptical galaxies have smooth, featureless light-profiles and range in shape from nearly spherical to highly flattened, and in size from hundreds of millions to over one trillion stars. In the outer regions, many stars are grouped into globular clusters. Most elliptical galaxies are composed of older, low-mass stars, with a sparse interstellar medium and minimal star formation activity They are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure. Collectively they are thought to make up about a quarter of all galaxies.

irregular galaxies were once spiral or elliptical galaxies but were deformed by gravitational action. they are shapeless.

You hold a spherical salad bowl 50 cm in front of your face with the bottom of the bowl facing you. The salad bowl is made of po
nataly862011 [7]

Answer:

a) q = 39.29 cm ,  b)   h ’= - 3.929 cm  the image is inverted  and REAL

Explanation:

For this exercise we will use the equation of the constructor

          1 / f = 1 / p + 1 / q

where f is the focal length of the salad bowl, p and q are the distance to the object and the image

The metal salad bowl behaves like a mirror, so its focal length is

           f = R / 2

           f = 44/2

           f = 22 cm

a) Suppose that the distance to the object is p = 50 cm, let's find the distance to the image

           1 / q = 1 / f  - 1 / p

           1 / q = 1/22 - 1/50

           1 / q = 0.0254

            q = 39.29 cm

b) to calculate the size of the image we use the equation of magnification

           m = h’/ h = - q / p

            h ’= - q / p h

            h ’= - 39.29 / 50 5

            h ’= - 3.929 cm

the negative sign means that the image is inverted

as the rays of light pass through the image this is REAL

A dentist using a dental drill brings it from rest to maximum operating speed of 391,000 rpm in 2.8 s. Assume that the drill acc
krek1111 [17]

Answer:

a

    \alpha  =  2327.7 \ rev/s^2

b

   \theta = 9124.5 \ rev

Explanation:

From the question we are told that

    The maximum  angular   speed is  w_{max} =  391000 \ rpm  =  \frac{2 \pi  *  391000}{60} =  40950.73 \ rad/s

     The  time  taken is  t =  2.8 \ s

     The  minimum angular speed is  w_{min}= 0 \ rad/s this is because it started from rest

     

Apply the first equation of motion to solve for acceleration we have that

       w_{max} =  w_{mini} +   \alpha  *  t

=>     \alpha  = \frac{ w_{max}}{t}

substituting values

       \alpha  = \frac{40950.73}{2.8}

       \alpha  =  14625 .3 \  rad/s^2

converting to rev/s^2

  We have

           \alpha  =  14625 .3 *  0.159155 \ rev/s^2

           \alpha  =  2327.7 \ rev/s^2

According to the first equation of motion the angular displacement is  mathematically represented as

       \theta  =  w_{min} * t  + \frac{1}{2} *  \alpha  *  t^2

substituting values

      \theta  =  0  * 2.8  + 0.5  *  14625.3  *  2.8^2

      \theta  = 57331.2 \  radian

converting to revolutions  

        revolution = 57331.2 *  0.159155

        \theta = 9124.5 \ rev
