In other words, accuracy describes the difference between the measurement and the part's actual value, while precision describes the variation you see when you measure the same part repeatedly with the same device
Answer:
Direct current.
Explanation:
The electric current is defined as the electric charge flowing per unit time. There are two types of current i.e. direct current and alternating current. The unidirectional flow of current describes the direct current. It is said so because the direct current flows only in one direction. This type of current flows in semiconductors, insulators, conductors etc. It is also known as DC current.
Answer:
During start total turns
After half of the time total turns
Total number of turns during it stop
After half of the time total turns
Explanation:
Initially the machine is at rest and then starts rotating with speed 3550 rev/min
now we will have
now we know that it took 10 s to reach the speed
so angular acceleration is given as
now it stops in 31 s so the angular deceleration is given as
now initially number of turn to reach the given speed
number of turns during it stop
Now during startup speed after t = 5 s is given as
now during it stop the speed after half the time is given as
now the number of turns is given as
