The energy produced by the headlamp at the end of 5 minutes is determined as 1,440 J.
<h3>
Energy supplied by the lamp</h3>
The energy supplied by the lamp is calculated as follows;
E = Pt
E = IVt
where;
- I is current = 0.4 A
- V is voltage = 12 V
- t is time = 5 mins = 5 x 60 s = 300 s
E = 0.4 x 12 x 300
E = 1,440 J
Thus, the energy produced by the headlamp at the end of 5 minutes is determined as 1,440 J.

Answer:
Plastic heats up faster :)
Explanation:
30mi/6hrs is a speed of 5 mph, which converts to a pace of 12 min/mi.
In fresh water sound waves travel at 1497m/s at 25 degrees, I'll assume that's the characteristics of the water.
If it's 0.01s then you need to divide the speed by 100 to get the, 14.97, however it gets there and back in that time so you need to halve it.
<u>7.485m</u>
