Answer:
The direct current that will produce the same amount of thermal energy is 1.83 A
Explanation:
Given;
maximum current, I₀ = 2.59 A
The average power dissipated in a resistor connected in an AC source is given as;
Where;
The average power dissipated in a resistor connected in a DC source is given as;
where;
is direct current
Solve equation (1) and (2) together;
Therefore, the direct current that will produce the same amount of thermal energy is 1.83 A
I don't know about hard to make, but it's impossible to make a mechanical wave transmit energy through a vacuum.

Do both cars leave the starting line at the same time ? That's kind of important. I'll assume that they both start out at the same time, and now I'll proceed to answer the question that I have invented.
-- Car B moves 4 m/s faster than Car A .
-- So Car-A's lead shrinks by 4 meters every second after they start.
-- It takes (10/4) = 2.5 seconds for Car-A's lead to shrink to zero.
-- So Car-B overtakes Car-A <em>2.5 seconds</em> after they start.
Answer:
When a bridge is used for long time It lises its elastic .Therefore ,the amount of strain in the bridge for a given stress will become large and ultimately, the bridge may collapse .This is why the bridge are declared unsafe after a long time.
