The main morphological types of galaxies are elliptical, spiral, and irregular.
Based on their morphology , galaxies have been classified into 3 types namely elliptical, spiral, and irregular.
These galaxies have various sizes and shapes ranging from dwarf galaxies to giant galaxies.
Elliptical Galaxy:
- The shape of it is generally circular
- These are the largest among all the types of galaxies because according to astronomers, it is formed by the merger of other small galaxies.
- Their rotational pattern is symmetric.
Spiral Galaxy:
- A spiral galaxy consists of a bright nucleus surrounded by a thin outer disk forming a spiral shape.
- This type of galaxy is the most common in our universe.
- It is divided into three classes: Spiral a, Spiral b, and Spiral c.
- Their rotational pattern has circular symmetry.
Irregular Galaxy:
- These types of galaxies have no central nucleus and irregular arms which are bluish.
- They don’t have any rotational symmetry.

Answer:
I hypothesis that the motion involving the balls in the experiment were moving to create data.
Explanation:
I hope this helps!
Because the heat of the fire diffuses into the atmosphere and then we absorb it into our body
Mass=142g
K.E=128 J
Speed or Velocity=?
K.E=1/2*m*v^2
128=1/2*142*v^2
128=72*v^2
v^2=128/72
v^2=1.777
by taking square rt
v= 1.333ms-1
so the speed will be 1.333 ms-1
Answer:
car. The car starts from rest at sea level and has a speed of 29.0 m/s at an altitude of 2.20x10^2 m above sea level. Obtain the work done on the car by the combined forces of friction and air resistance, both of which are nonconservative forces.
