Why is air resistance considered a type of contact force?

Chemistry
1 answer:
MAVERICK [17]3 years ago
3 0

Answer:

Explanation:

The normal force is the support force exerted upon an object that is in contact with another stable object. The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object.

a 9.84 ounces ingot of unknown metal is heated from 73.2 degrees fahrenheit - 191.2 degrees fahrenheit this requires 3.912 calor
Gekata [30.6K]

The SI unit of specific heat is J per gram per degree Celsius. Thus it follows that specific heat could be calculated in this way:

Specific Heat = Energy / (mass x change in temperature)

Thus,

Specific Heat = 3.912 cal / (9.84 oz x (191.2 ˚F – 73.2 ˚F))

Specific Heat = 3.369 x 10^-3 cal/oz-˚F

What type of bond allows heat and electricity to move freely throughout the material?
OLga [1]

That would be an ionic bond since it has electrons to spare, rather than a convalent bond where all the electrons are taken up thus it is not a good conductor

Must all four hydrogen atoms lie in the same plane? If not, what is the spatial relationship among them? Why?
RoseWind [281]

Answer:

We are considering an Allene molecule here, CH2CCH2. To answer your question, NO, they don't have to lie on the same plane. The spatial arrangement between them is that the center carbon that forms these pi bind in the left and right are PERPENDICULAR to each other.

Explanation:

We see here that The terminal carbons are sp2 hybridized, and form three σ-bonds each which means that each terminal carbon has one unhybridized p-orbital. The central carbon atom is sp hybridized, and forms two σ-bonds which means it has two unhybridized p-orbitals. For better understanding, let's call these two orbitals px and py. Summarily, These orbitals are perpendicular to each other

The dopamine molecule has an intermediate hydrophobicity. Edit the dopamine molecule so that it is more hydrophobic.
yulyashka [42]
You should edit the dopamine molecule by tampering with its polar groups. Polar groups affect chemical's physical properties including hydrophobicity.
