ANSWER
Power stroke
EXPLANATION
At the power stroke stage, the piston is forced to move down by the expanding gases as both intake valve and exhaust valve are closed.
A spark from the spark plug contributes to ignition of the compressed fuel air mixture to released energy to perform work.
The answer///////////b, 5 orbits
Maximum number of electrons in nth energy level
Now
Max electrons
Explanation:
The given data is as follows.
= 0.483, = 0.173 M,
= 0.433 M, = 0.306 M,
= 9.0 atm
According to the ideal gas equation, PV = nRT
or, P =
Also, we know that
Density =
So, P = MRT
and, M =
=
=
= 0.368 mol/L
Now, we will calculate the cell potential as follows.
E =
=
=
=
= 0.483 - 0.0185
= 0.4645 V
Thus, we can conclude that the cell potential of given cell at is 0.4645 V.
Whereas semidiurnal tides are observed at the equator at all times, most locations north or south of the equator experiencetwo unequal high tides and twounequal low tides per tidal day; this is called a mixed tide and the difference in height between successive high (or low) tides iscalled the diurnal inequality.
