Answer:
Ωmass
Explanation:
If there were no dark energy in the universe, the value of Ωmass would determine the evolution and fate of the universe.
Answer:
Part a)
Part b)
Part c)
Explanation:
As we know that car start from rest and reach to final speed of 87 mph
so we have
now we have
Part a)
acceleration is rate of change in velocity
Part b)
distance moved by car with uniform acceleration is given as
Part c)
As we know that the car start from rest
so final speed after t = 10 s
Given that:
spring compressed ( x) = 0.2 m
Work (W) = 24 J
determine , spring constant (x)=?
We know hat ,
Work (W) = (1/2). k.x²
24 = 1/2 ( k × 0.2²)
48 = k × 0.2²
<em> k = 1200 N/m</em>
Explanation :
Our solar system was formed about 4.6 billion years ago. It is formed when gravity exerted low-density cloud of interstellar gas and dust. The massive cloud of gas and dust is called as Orion Nebula.
In a small area, the overdensity of clouds occurs. This caused the contraction, to begin. Due to this contraction the potential energy gets converted into kinetic energy of individual gas particles.
Hence the correct option is " materials were pulled together by the gravity". This is the one of the evidence used to indicate the beginning of the solar system.
