The amount of seawater that will be displaced would be 1.3274 x 
<h3>Density and volume</h3>
Density = mass/volume.
Since a floating object displaces its own weight, a 4247 tons ship will also displace the same amount of water.
4247 tons of seawater = 3.8528 x 
g
volume of 3.8528 x g seawater = mass/density = 3.8528 x g/1.025 = 3758829268.29 cubic centimeter.
3758829268.29 
= 132741.80 or 1.3274 x

The words that complete the blanks are hypothesis and experimentation.
<h3>What is scientific knowledge?</h3>
The process by which scientists obtain information and establish knowledge is;
Observation ---> hypothesis ------> experiments ------> Theory -------> Law.
Thus after the process of observation what we have is merely a scientific hypothesis that needs to pass through the process of rigorous experimentation before it is proven to be true.
Thus the words that complete the blanks are hypothesis and experimentation.

The answer is C.
the ice is changing its state of matter but not its composition. it is still water, you just have to freeze it up again.
hope this helps!
Answer:
d). A catalyst lowers the activation energy for a chemical reaction.
Explanation:
From the given choices, it is true that a catalyst lowers the activation energy for a chemical reaction.
The activation energy is the energy barrier that must be overcome before a chemical reaction can occur.
Some reactions have very high activation energy and would not occur without the introduction of a catalyst.
The catalyst brings the reactants into contact by removing the energy deficiency in the system.
Answer:decreases
Explanation it takes energy from it to change
