Answer:
Alloys and Composites
Explanation:
<u>Drill bits are made of alloys</u> because alloys are very much resistant to corrosion and are created when one or multiple metals are mixed with other elements that are non-metallic in nature. Due to their greater strength, they are used in the power drills in order to create borehole drills at the mining site. Borehole drilling is commonly done in order to understand the sub-surface strata before mining.
<u>The bodies along with the handles of power drills are constructed of composite insulators</u> because within the composites there is the absence of free electrons that has the ability to flow and produce electricity. So they are considered to be used as a good insulator.
Answer:
A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink. A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.
Explanation: hope this helps :) sorry if it's wrong :(
There are four F atoms on the products side.
Since two more F atoms are required on the reactant side, you multiply the number of F2 molecules by two.
So 2 should be placed in front of F2
Answer:
I think everything that's there is correct.
Explanation:
Bleach with pH of about 12.5 would be a strong base.
Milk with pH of 6.5 and Blood with pH around 7 would be neutral.
Battery acid with pH below 1 is strong acid and orange juice is weak acid.
