How many times did thomas edison mess up the light bulb

Physics

Umnica [9.8K]3 years ago
4 0
<h2>Answer: 10,000 times </h2>

Thomas Alva Edison was a North American scientist and inventor who is credited with the design of the electric bulb and many other patented inventions.

However, the bulb did not come out on the first attempt, and was sometimes questioned by his repeated "failures". But his patience and perseverance paid off, after approximately 10,000 attempts, he managed to obtain an incandescent bulb that would last for a long time.

It should be noted that Edison was once asked if he considered that he had had many failures before making the bulb work, hence his famous phrase:

<h2><em>“I have not failed 10,000 times—I’ve successfully found 10,000 ways that will not work.” </em></h2>

That is why Edison is considered an example of perseverance.

How can you drop two eggs the fewest amount of times, without them breaking?
MrMuchimi

Answer:

Both eggs are identical. The aim is to find out the highest floor from which an egg will not break when dropped out of a window from that floor. If an egg is dropped and does not break, it is undamaged and can be dropped again. However, once an egg is broken, that's it for that egg.

A 2.5 kg tribble is placed in a bucket and whirled in a 1.4 m radius vertical circle at a constant tangential speed. If the forc
Over [174]

Given that,

Mass of a tribble, m = 2.5 kg

Radius, r = 1.4 m

The force on the tribble from the bucket does not exceed 10 times its weight.

To find,

The maximum tangential speed.

Solution,

The force acting on the tribble is equal to the centripetal force.

F = 10mg

The formula for the centripetal force is given by :

F=\dfrac{mv^2}{r}

v is maximum tangential speed

v=\sqrt{\dfrac{Fr}{m}} \\\\v=\sqrt{\dfrac{mgr}{m}} \\\\v=\sqrt{{10gr}} \\\\v=\sqrt{10\times 9.8\times 1.4} \\\\v=11.7\ m/s

So, the maximum tangential speed is 11.7 m/s.

A boy weighing 50 kg is running at 2m/s. What is its kinetic energy? *<br> 10 points
pentagon [3]
The answer is 100.
The formula is KE = 1/2mv^2
Then you plug in 50 to the m
And 2 to the v . That’s how I got 100 .
Hope this helps
