Frequency = 1 / (period) = 1 / (0.002 sec) = 500 Hz
Answer:
4050 gallons
Explanation:
In first half and hour both pumps are working property . There for it give, 45
gallons per minute . Half and hour is equal to 30 minutes.After one pump was broken only one pump is working 30 minutes .
For 1st 30 minutes ,( 2 pumps are working )
Gallons = 45 * 30 *2 = 2700 gallons
2nd 30 minutes ( 1 pump is working )
Gallons = 45*30*1 = 1350 gallons
Total gallons = 2700+1350
= 4050 gallons

Answer:
Value of is 7.466 ohm
Explanation:
Let emf of the battery is e
In first case when only is there current through battery is 2.2 A
So
......eqn 1
In second case current is reduced to 1.6 A when additional resistance of 2.8 ohm is added in series
So
....eqn 2
Fro eqn 1 and eqn 2
So value of is 7.466 ohm
