Answer:
contains many young stars
Explanation:
Irregular galaxies have <em>no definite shape</em>, which means that the first option is incorrect. They are definitely not round.
However,<u> they contain many young stars because the degree of star formation is fast.</u> They also contain old stars. Thus, the second choice is correct.
The "spiral galaxy" is the type of galaxy that has arms that extend from the center. These arms look "spiral," which influenced its name. This makes the last choice incorrect.
They are actually <u>smaller than the other types of galaxies.</u> This makes them <em>prone to collisions</em>. This makes the last choice incorrect.
Answer:
Using the Fundamental Equation of Wave, we have:

Answer:
287.19 kg.m²
Explanation:
Given that :
The mass M of the horizontal platform = 111 kg
The radius R of the uniform disk = 1.67 m
mass of the person standing 
= 64.7 kg
distance of the person standing 
= 1.15 m
mass of the dog 
= 25.7 kg
distance of the dog 
= 1.35 m
Considering the moment of inertia of the object in the system; the net moment of the inertia can be expressed as:
= 
= 
= 287.19 kg.m²
As velocities are tangent, the value of both Particle A and Particle B would be same for that point O (Intersecting point)
a = v / t
Here, v = 7, t = 6
So, a = 7/6
a = 1.17
As the graph is decreasing, value of acceleration would be negative.
So, a = -1.17 m/s²
In short, Your Answer would be Option C
Hope this helps!
