An infant galaxy that is studied through the use of radio waves is called QUASAR.
Quasar are astronomical object, which have very high luminosity and they are found in the centers of some galaxies. Scientists believed that quasar are centers of distant galaxies. Radio waves is used to study quasar because they emit a huge amount of radio waves.
Answer:
true
Explanation:
I did this unit for science
The average velocity of Sandy is given by the total distance covered S divided by the total time taken t:
The total distance covered is
while the total time taken is 2 hours + half an hour (for the rest) + 1 hour and half, so
Therefore, the average velocity is
Answer: Temperature is the average kinetic energy of the molecules (how hot or cold something feels). Heat energy is the energy created y the motion of the molecules in an object. Heat flows from hot body to cold body. Temperature rises when heated and falls down when an object is cooled down.
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale. Each of these scales uses a different set of divisions based on different reference points, as described in detail below.
