<span>Engineers place tolerance on dimensions since
the when engineers use tolerance, buildings and constructions projects like
tall towers, roads, and bridges become more reliable, strong and stable. In
harnessing tolerance, the end product that is made by the engineers,
specifically buildings like schools, hospitals, malls and skyways are sturdy
and dependable.</span>
Answer: 18.02 g/mol
The average mass of one H2O molecule is 18.02 amu. The number of atoms is exact, the number of moles is exact; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.
Answer: Elements in the same period have the same number of electron shells; moving across a period ( elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
Answer:
213 s
Explanation:
Slope is the ratio of change in vertical distance to change in horizontal distance.
Slope = vertical height / horizontal height
Therefore:
6.4% = vertical height / 12.42
vertical height = 6.4% * 12.42
vertical height = 0.8 miles
The distance travelled by the car (s) is:
s² = 0.8² + 12.42²
s² = 154.9
s = 12.45 miles
Acceleration (a) = 2.93 ft/s^2 = 0.00055 mile/s²
initial velocity (u) = 0, final velocity = 203 mph
Using:
s = ut + 0.5at²
12.45 = 0.5(0.00055)t²
t =213 s
Answer:
friction from the ground rubs on the tire which gives it more force to move forward,
Explanation: without friction the bike wont be able to use the motion to move forward. but the tires start to wear out easily.
