A. freezing, when water turns to ice the water is turning from a liquid to a solid.
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)

The ideal mechanical advantage of the screwdriver is 47
Explanation:
In this problem, the screwdriver acts as a lever.
The Ideal Mechanical Advantage (IMA) of a lever is given by:
where:
is the distance of the point of application of the input force from the fulcrum
is the distance of the output force from the fulcrum
In this problem, we have:
, since the fulcrum is 0.500 cm from the end
(the distance between the fulcrum and the point where are we holding the screwdriver)
Substutiting,
