Given our understanding of Galactic space searches and techniques, we can confirm that the Inner Galactic Plane Survey conducted with the Allen Telescope Array is an example of a targeted search.
A targeted search is when a technique is used <u>not to sweep for general information</u>, but to identify points at which <em>specific processes </em><u>occur</u>. In the case of the Inner Galactic Plane Survey, the goal is to find points of star formations.
Therefore, we can say that the Inner Galactic Plane Survey conducted with the Allen Telescope Array in northern California is an example of a targeted search.

Answer:
The reason for phonograph installation is to provide information about humans to interstellar aliens.
Explanation:
Phonographs are archaic forms of gramophone which are able to record and reproduce sound.Phonographs were used in early days in voyagers to help transmit information about humans to nearby alien species in space.
Matter is generally any physical substance, and it's all around us... a form of matter would be liquid, and water is a liquid.
Answer:
Explanation:
When the skier reaches the bottom of the slope , height lost by it
h = 50 sin32 m
= 26.5 m
potential energy lost
= mgh
Gain of kinetic energy
= 1/2 mv²
mgh = 1/2 mv²
v = √ 2gh
= √ (2x9.8 x 26.5)
= 22.8 m /s
b )
Let μ be the coefficient of kinetic friction required.
friction force acting
= μmg
work done by friction in displacement of d (40 m ) on horizontal surface
- μmg x d
This negative work will be equal to positive kinetic energy of the skier on horizontal surface .
= μmg x d = (1/2) m v²
μ = v² / (2 gd)
= 519.4 / (2 x 9.8 x 140 )
= .19
