Answer: Decomposition
Explanation:
A chemical break down of a reactant into two or more products is known as Decomposition reaction. A substance decomposes to simpler substances.
It can be represented as:
AB → A + B
Example, water breaks down into oxygen and hydrogen
2 H₂O → 2 H₂ + O₂
Thus, the correct answer is:
A Decomposition reaction occurs when a substance is broken down into two or more simpler substances in a chemical reaction.
b. the perfect cosmological principle
c. the oscillating universe theory
d. the steady state theory
Answer: b. the perfect cosmological principle
Explanation:
The perfect cosmological principle is the extension of the cosmological principle. It states that the universe is homogeneous. It looks same from everywhere. It will look the same. It will never change over time instead of some of the gross changes occurring in the universe.
Answer:
The momentum is actually 1.87 g m/s
Explanation:
The other answer was right however that isn't an answer to the question.
Answer: intensity
Explanation:
The coordinates of the event in system K can be found using the Lorentz transformation equations, and they are (10/3 m, 3.5 m, 3.5 m, 8/3 m/c).
The Lorentz transformation equations relate the coordinates of an event in one reference frame to the coordinates of the same event in another reference frame that is moving with a constant velocity relative to the first reference frame.
The equations are as follows:
x = γ(x' + vt')
y = y'
z = z'
t = γ(t' + vx'/c^2)
Where γ is the Lorentz factor, which is given by:
γ = 1/√(1-v^2/c^2)
In this case, v = 0.8c, so γ = 1/√(1-(0.8c)^2/c^2) = 5/3.
Plugging in the values for x', y', z', t', v, and γ into the Lorentz transformation equations, we get:
x = (5/3)(2 m + (0.8c)(0)) = 10/3 m
y = 3.5 m
z = 3.5 m
t = (5/3)(0 + (0.8c)(2 m)/c^2) = 8/3 m/c
Therefore, the coordinates of the event in system K are (10/3 m, 3.5 m, 3.5 m, 8/3 m/c).
