Answer:

Explanation:

1)Solution,

Distance(s)=30m

Time taken(t)=11s

Now,

Average velocity=s/t=30m/11s=2.72m/s

2)Solution,

Distance(s)=20km=20x1000m=20000m

Time(t)=9:30-8:30=1:30=60+30 min=90min=90x60=5400s

Now,

Average velocity=s/t=20000m/5400s=3.7m/s

How long was a 50 W lightbulb left on for if 500,002 J were burned?

saveliy_v [14]

" 50 W " means " 50 Watts " or " 50 Joules per second ".

(500,002 J) / (50 J/sec) = <em>10,000.04 seconds</em>

(That's 2 hours 46 minutes 40.04 seconds.)
