Explanation :
(1) Big bang : (1) The most accepted theory on the origin of the universe.
This theory shows the expanding of the universe from high density and high-temperature states.
(2) Steady state : (3) All is the same and will always stay the same.
Steady state means that the properties of any system remain the same always.
(3) Oscillating universe : (4) Agrees with the big bang theory but insists the universe expanded much quicker.
Oscillating universe theory is the result of big bang theory.
(4) Inflation Choices : (2) it's like an inflating and deflating balloon that never stops.
In cosmology, cosmic inflation or deflation is just the expanding and contraction of the universe.
So, the statements and the choices are related as:
(1)-(1)
(2)- (3)
(3)-(4)
(4)-(2)
Answer:
Blue
Explanation:
Objects absorb and reflect light differently according to their physical characteristics. The color we perceive of an object is the range of the spectrum of light that it does not absorb. We capture that "rejected" light, through the eyes, thanks to its structure.
Answer:
True
Explanation:
Newtons Law states that "When a net force acts on a body, it produces acceleration in the body in the direction of the net force. The magnitude of acceleration is directly proportional to the net force and inversely proportional to its mass."
So, it's mathematical form is
=> a ∝ F (1)
=> a ∝
Combining the proportionality
=> a ∝
=> F ∝ ma
Using k as proportionality constant.
=> F = kma
Here k = 1
=> F = ma (Proved)
The molecule that trap's the sun's energy is chlorophyll.
