The correct answer is D. Let us analyze briefly each concept in order to justify this answer.
A) Chemical changes are changes in which the nature of the material changes; for example when paper burns. Cutting paper is not a chemical change because the substance of the paper remains the same. When changes are very drastic like the start of the Universe or in radioactive materials, there are nuclear reactions which change the substance and are another category of processes.
B) Cosmic Redshift is an aftermath of the dilation of the Universe. Galaxies that are moving away from us give off a lower frequency light, hence their light is becoming "more red". This is not the cause of the production of light elements.
C) Cosmic Background Radiation is a direct aftermath of the Big Bang and it is predicted by the model. Because we have that at the start, all matter was concentrated together, it was very dense and it radiated. As the Universe dilated, this radiation became less intense, but it is still detectable.
D) Nucleosynthesis is the term we are looking for. It literally means: composition of nuclei. It refers to how protons and neutrons combined in the first 3 minutes to form nuclei of light elements
Since the two charts after the collision stick together, we are dealing with a perfectly inelastic collision.
First, we need to find the speed of the two charts after the collision. In order to do so, we consider the conservation of momentum:
m₁·v₁ + m₂·v₂ = (m₁ + m₂)·v
We can solve for v, considering also that v₂=0
v = m₁·v₁ / (m₁ + m<span>₂)
= 0.31 </span>· 0.90 / (0.31 + 0.50)
= 0.34 m/s
The kinetic energy lost (which is transformed into bounding energy between the two charts) will be the difference between the total kinetic energy before the collision and after the collision:
ΔE = E₁ - E₂ = 1/2·m₁·v₁ - 1/2·(m₁ + m₂)·v
= 1/2(0.31)(0.90) - 1/2(0.81)(0.34)
= 0.1395 - 0.1377
= 0.0018J
Hence, the correct answer is ΔE = <span>0.0018J</span>
