Answer:
16kg/s
Explanation:
The formula for acceleration is [ a = f/m ] where f = force and m = mass
a = 4/0.25
a = 16
Best of Luck!
I am pretty sure that <span>If I were asked to compare matter in solid, liquid, and gaseous states, the statement which would best defined a gas is </span>highest energy, highest molecular motion, and least dense packaging of molecules. I choose this one because it's not sensible to <span>heat CO2 (in case of safety) and in the last option the amount of energy is not satisfying.
Hope it helps!</span>
Answer:
Explanation:
The blow-by gases that escape past the piston rings and get into the crankcase are mostly unburned fuel-air mixture.
The fuel is largely a mixture of hydrocarbons (HCs)
.
The PCV system captures these gases and feeds them back to the cylinder for further combustion.
A. is wrong. Carbon dioxide exits through the exhaust.
C. is wrong. Most of the oxygen in the incoming air is used for combustion in the cylinders.
D is wrong. The NOx gases exit via the exhaust and are trapped by the catalytic converter.
Answer: The double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.
Explanation:
Chemical compounds that have conjugated planar ring systems where there are delocalized pi-electron clouds are present in place of individual alternate and single bonds.
This means that electrons present in a double bond of alkene are in conjugation.
Therefore, we can conclude that the double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.
