1.    W = P × t
W = 60 × 10
W = 600 J

2.   W = P × t
W = 2000 × 120
W = 240.000 J

3.   P = W ÷ t
P = 1500 ÷ 30
P = 50 W

4.   t = W ÷ P
t = 5000 ÷ 500
t = 10 s

5.   W = P × t
W = 1800 × 180
W = 324.000 J

6.   P = W ÷ t
P = 12.000 ÷ 240
P = 50 W

7.    W = P × t
W = 450 × 7200
W = 3.240.000 J

8.   P = W ÷ t
P = 90.000 ÷ 3600
P = 25 W

9.   t = W ÷ P
t = 67.500 ÷ 750
t = 90 s

10.  P = W ÷ t
P = 1.800.000 ÷ 18.000
P = 100 W
