The height a ball bounces is less than the height of the previous bounce due to friction. The heights of the bounces form a geom
AlladinOne [14]

Answer:

Explanation:

Let the first height be h . second height .75h

third height .75h . fourth height .75²h

fifth height .75²h , sixthth height .75³ and so on

Total distance consists of two geometric series as follows

1 ) first series

h + .75h + .75²h + .75³h......

2 )  second series

.75h +.75²h +.75³h + .75⁴h .......

Sum of first series :

first term a = h , commom ratio r = .75

sum = a / (1 - r )

= h / 1 - .75

= h / .25

4h

sum of second series :--

first term a = .75 h , commom ratio r = .75

sum = a / (1 - r )

= .75h / 1 - .75

= .75h / .25

3h

Total of both the series

= 4h + 3h

= 7h .

h = 1 m

Total distance = 7 m

For the radial speed of an astronomical object to be determined, what must the object’s spectrum contain?
Ainat [17]

Answer:

Either absorption or emission lines

Explanation:

For the radial speed of an astronomical object to be determined with a Doppler shift, what must we be able to see in the object's spectrum, Either absorption or Emission lines.

Asorption and Emission line explained below;

  • Absorption lines are usually seen as dark lines, or lines of reduced intensity, on a continuous spectrum.
  • An emission line will appear in a spectrum if the source emits specific wavelengths of radiation.
