A magnetic pickup is used to detect the shaft speed of a turbocharger. A standard hexagonal nut is used to excite the pickup. If the shaft is turning 36000 rpm, how many positive pulses will be created per second

There are 3600 positive pulses will be created per second.

Explanation:

In this case, we need to find number of positive pulses will be created per second. It is mentioned that the shaft is turning 36000 rpm. We know that a hexagonal nut contains 6 faces. The speed of shaft in revolutions per second is given by :

So, the number of pulses created per second is :

So, there are 3600 positive pulses will be created per second. Hence, this is the required solution.

truck y has a greater velocity than truck x.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
