Answer:
Intake, compression, power, and exhaust
Explanation:
A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.
Answer:
Pb(NO3)2
Cd(NO3)2
Na2SO4
Explanation:
In the first part, addition of HCl leads to the formation of PbCl2 which is poorly soluble in water. This is the first precipitate that is filtered off.
When the pH is adjusted to 1 and H2S is bubbled in, CdS is formed. This is the second precipitate that is filtered off.
After this precipitate has been filtered off and the pH is adjusted to 8, addition of H2S and (NH4)2HPO4 does not lead to the formation of any other precipitate.
The yellow flame colour indicates the presence of Na^+ which must come from the presence of Na2SO4.

The statement that is true is one of the objects must have a very large mass.
The more the scale of the masses, the more the scale of the gravitational pressure (additionally referred to as the gravity pressure). The gravitational pressure weakens swiftly with growing distance among masses. The gravitational pressure is extraordinarily difficult to discover until as a minimum one of the gadgets has quite a few mass.
The gravitational pressure among gadgets is proportional to their hundreds and inversely proportional to the rectangular of the space among their centers.
