Answer:
C
Explanation:
If a pulley system has an efficiency of 74.2%, then only that fraction of the work performed will be useful. 74.2%=0.742. 0.742*200 is about 148J. Hope this helps!
Explanation:
initial velocity U = 20m/s
Final velocity V = 35m/s
time = 15.0 secs
change in velocity = 35 - 15
= 20m/s
acceleration a = change in velocity/time V/t
a = (35-20)/15
a= 15/15
Hence, your acceleration is 1m/s^2
Answer:
Number of turns in secondary is 20
Current in primary is 0.96 A
Explanation:
We have given number of turns in primary
Voltage across primary of transformer
Current in secondary coil
Voltage across secondary
For transformer we know that
So
So number of turns in primary is 20
Now
Current in primary of transformer is 0.96 A
