Answer:
Both technicians A and B are correct
Explanation:
A pump check valve is device that allows the flow of any fluid in only one direction and prevents the flow from the reverse direction.
When the pump operates, there is pressure that develops inside the pump. Now when the pump is shut down, the pump check valve is able to hold the pump pressure for sometimes until the pressure inside the pump becomes normal.
When the pump check valve is defective, there is a drop in pressure inside the regulator or the pump. Because of the drop in pressure, it takes long time for the pump to start and hence longer cranking time.
Thus both technician A and technician B is correct.
Hence the answer is ---
Both technicians A and B are correct
Squanto was a pequot who taught colonists how to survive. They were the Native American of the Patuxet tribe, also known as Tisquantum.
Squantos served as an interpreter and guide for the Pilgrim immigrants at Plymouth during their first winter in the New World. Around 1580, Squanto was born close to Plymouth, Massachusetts. The details of his early life are unknown. Thomas Hunt, an English explorer, kidnapped him in 1614 and took him to Spain, where he was sold into slavery. Squanto managed to flee and eventually made it back to North America in 1619. After that, he went back to the Patuxet area, where in the 1620s he worked as an interpreter and guide for the Pilgrim colony in Plymouth. He passed away at Chatham, Massachusetts, in November 1622

You might be surprised to find, however, that the first seismometer was invented in China in 132 AD by a Chinese astronomer, mathematician, engineer, and inventor called Zhang Heng. The instrument was said to resemble a wine jar six feet in diameter, with eight dragons positioned face down along the outside of the barrel, marking the primary compass directions. In each dragon’s mouth was a small bronze ball. Beneath the dragons sat eight bronze toads, with their broad mouths gaping to receive the balls. When the instrument sensed an incoming seismic wave, one of the balls would drop and the sound would alert observers to the earthquake, giving a rough indication of the earthquake’s direction of origin. The device is said to have been very accurate and could detect earthquakes from afar, and did not rely on shaking or movement in the location where the instrument was positioned. The first ever earthquake recorded by this seismograph was supposedly somewhere in the east. Days later, a rider from there reported this earthquake. Moreover, it had the most wicked ornaments. They don’t make scientific instruments like they used to! Of course, the insides of the seismometer was filled with a sensing mechanism of some sort, the contents of which have been lost in time. In all likelihood, a simple or inverted pendulum was employed, according to experts.
