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:
The momentum of the bowling ball is 53.4 kg-m/s.
Explanation:
We have,
Mass of a bowling ball is 8.9 kg
Speed of the ball is 6 m/s
It is required to find the momentum of the ball. The momentum of an object is given in terms of its mass and speed as :
p = mv
So, the momentum of the bowling ball is 53.4 kg-m/s.
The answer is B thank me later !
I don’t know how air would be an insulator so I’m guessing that one isn’t
