The power dissipated by the LED is 20 Watts and the work done for 1 hour 15 minutes is 56.25 kJ.
<h3>What is electrical power?</h3>
Electrical power is the rate at which electrical work is done.
- Electrical power = voltage × current
The LED is 75% efficient means that 75% of power dissipated by the LED is converted to light.
Total power dissipated = 5 × 2.5 = 12.5 Watts
- Work done = power × time (in seconds)
Work done = 12.5 × (1 × 3600 + 15 × 60)
Work done = 56250 J = 56.25 kJ
Therefore, the power dissipated by the LED is 20 Watts and the work done for 1 hour 15 minutes is 56.25 kJ.

Answer:
7.5 km
Explanation:
h5 per hour means that he traveled 5 km in 1 our. And then half of the hour, which means half an hour 5 km which is 2.5.
5 + 2.5 = 7.5
or just 1.5 x 5 = 7.5
Answer:
Self inductance, 
Explanation:
It is given that,
Length of the coil, l = 5 cm = 0.05 m
Area of cross section of the coil, 
Number of turns in the coil, N = 130
The self inductance relates the magnetic flux linkage to the current through the coil and it is given by :
L = 0.000127 Henry
or
So, the self inductance of the coil is 127 microhenry. Hence, this is the required solution.
I have no idea what lesson you're talking about, but I am multilingual so I'm sure my answer can suffice for the small amount of details.
One advantage of being bilingual as a child is that, when faced with text written in a different language nobody else but you understands, you can save everyone's butt from taking out inaccurate translators for that text.
The disadvantage that follows that is the fact that people will now recognize you as that one dude that speaks every language, even if you don't. So, now, you have everybody coming up to you to translate everything they don't understand.
Another advantage is that you can read something everyone else would find disturbing (like, my graphic horror/action stories) without anybody understanding it because it's in another language.
The disadvantage that follows is that they're almost always going to be nosy brats and asking what every word means.
The last advantage I'll list is that you can get away with saying stuff. Like, "man, that woman must be on something", or, "darned drunkards", without starting up a fight with them, because, really, who's going to understand Thai way over in America? (I honestly wouldn't recommend risking it, though. Speaking of which...)
The last disadvantage here is the fact that you won't know who speaks these languages around you. For all you know, your best friend had understood every comment about the loony across the street and simply chose not to comment on it.
So, for the final conclusion, knowing different languages is great and all, but it's not that great.

Answer:</h3>
AgCl + NaNO₃
<h3>
Explanation:</h3>
- The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
- In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
- In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
- Therefore, the complete reaction is given by;
AgNO3 + NaCl → AgCl + NaNO₃
- But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.
