1 watt = 1 joule/sec
1800 watts = 1800 joules/sec
(1800 J/sec) x (20 min) x (60 sec/min)
= (1800 x 20 x 60) joules = 2,160,000 joules .
( 2.16 megajoules )
A parallel circuit - there are multiple branches at which current is able to to be pushed around the circuit.
Answer:
Acceleration(a) = 
v = final velocity = 5.5 m/s
u = initial velocity = 3 m/s
t = time = 9s
(approx)
A manufacturer of printed circuit boards has a design
capacity of 1,000 boards per day. the effective capacity, however, is 700
boards per day. recently the production facility has been producing 950 boards
per day. The design capacity utilization is (950/100) *100 = 95 %
