The camshaft is either chain or gear driven from the crankshaft. Because the engine is a four stroke, the camshaft will rotate at half the speed of the crankshaft. (the valves and fuel pump will only operate once for every two revolutions of the crankshaft).

Brazil is, quite simply, the largest coffee producer in the world.

This can be written as 16 km/min.
Now, 1 km/min = 60 km/hr. Therefore, 16 km/min =
16*60= 960 km/hr.
Distance travelled by the aircraft is 800 km.
Therefore, time taken will be Distance ÷ Speed.
=> Time = 800/960 = 0.833333 hours.
Now, speed of the car is 80 km/h. distance travelled by the car in 0.833 hours—
Distance = Speed * Time.
=>Distance = 80 * 0.833 = 66.64kms.
Therefore, the car travels 66.64 km , when the aircraft traveled 800 km.

According to Bohr, as per the energy level, the filling of electrons in each shell will be 2, 8, 8, 18, 32. The atomic number given are 2, 10, 18, 36, 54, 86 which shows that these elements have completely filled orbitals and are noble gases or zero group members.
