Given that:
Energy of bulb (Work ) = 30 J,
Time (t) = 3 sec
The power consumption = ?
We know that, Power can be defined as rate of doing work
Power (P) = Work(Energy supplied) ÷ time
= 30 ÷ 3
= 10 Watts
<em> The power consumption is 10 W.</em>

300 N
Explanation:
The net force acting on the arrow is given by Newton's Second Law:

where
m = 0.06 kg is the mass of the arrow
a = 5,000 m/s^2 is the acceleration of the arrow
Substituting the numbers into the equation, we find

Answer:
Explanation:
Average speed is found by adding together the total distances traveled by the athlete and divide that total by the total time it took.
Average velocity is vector, which means it includes direction. If the athlete heads one way and then turns around, his displacement might actually be negative! Yikes! Let's look at speed first:

Velocity is the displacements added together divided by the total amount of time it took. The displacement is the same as the distance here, since the athlete did not veer off his straight-path and didn't turn around.
Average velocity = average speed = 533.3 m/min
