Explanation
The light the fish absorbs is sunlight, the light reflecting is UV
Answer:
2 ohms
Explanation:
Hi there!
Ohm's law states that
where V is the voltage, I is the current and R is the resistance.
Plug in the given information (I=7.5, V=15) and solve for R

Divide both sides by 7.5 to isolate R

Therefore, the circuit resistance would be 2 ohms.
I hope this helps!
The total mechanical energy of the notebook is <u><em>19J</em></u>.
Mechanical energy is the sum of potential energy and kinetic energy. It has no kinetic energy, because it's not moving. So its potential energy is all the mechanical energy it has.
Answer:
1,500 km
Explanation:
300 km/h
300 kilometers PER <u><em>HOUR</em></u>
<u><em></em></u>
So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.
300 * 5 = 1,500
The train moves at 1,500 km in 5 hours.
Hope this helped!
