The Earth's weather and climate is dependent on the angle at which a specific point is positioned in relation to the sun. Points angled towards the sun will experience higher temperatures, thus turning water to vapor that eventually returns to the ground as rain as it cools in the atmosphere. In points angled away from the sun, this water evaporates slower and returns to the ground as sleet or snow.
Answer:
Ionic
Explanation:
Any metal with a nonmetal is an ionic bond due to the transfer of electrons.
Explanation:
Bromothymol blue changes colour from blue to yellow due to the high carbon dioxide content being exhaled and dissolved in the solution.
Answer:
a) significant figures b) decimal places
Multiplying/dividing ex: 1.33 * 4.4932 = 5.98 because the first component only has three sig figs while the second has five.
Adding/subtracting ex: 12.13 + 53.5763 = 65.71 we ignore the whole numbers and focus only on the decimal places. The first component only has two while the second has four. Hope this helps!
Given:
volume of 0.08 m³
density of 7,840 kg/m³
Required:
force of gravity
Solution:
Find the mass using density
equation.
D = M/V
M = DV
M = (7,840 kg/m³)(0.08 m³)
M = 627.2kg
F = Mg
F = (627.2kg)(9.8m/s2)
F = 6147N
