Explanation:
The fact that water is attracted to itself, a property called <u>cohesion</u>, leads to another important property, the liquid form of water is <u>more</u> dense than the solid form. As water solidifies into ice, the molecules must move apart in order to fit in to a crystal lattice structure, causing water to expand as it freezes. Because of this, <u>ice floats</u> and water sinks, which keeps the oceans liquid and prevents them from freezing solid from the bottom up.
Answer:
Force = 9600N
Explanation:
If this is the right question, there should have been a question before about the what the change in the momentum of the ball was. The answer to that was 9.6kg m/s. For this part, we divide this by the time taken which was 0.001s which give us the resultant force.
resultant force = change in momentum ÷ time
= 9.6kgm/s ÷ 0.001s
= 9600N
Answer;
3.45 × 10^-1
Explanation;
-Here we wish to write the number 0.345 as a coefficient times 10 raised to an exponent. To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45.
-The number of places to the left that you had to move the decimal point is the exponent.
= 0.345
= 3.45/10
= 3.45 × 10^-1
