Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, and the average height of the falls is about 50 m. Knowing

Andre45 [30]

Answer:

Power, $P=1.176\times 10^9\ W$

No of bulbs = 78400000

Explanation:

We have,

Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, it mean it is mass per unit time i.e. m/t.

It falls from a height of 50 m

The gravitational potential energy of falling water is given by :

P = mgh

Power is equal to the work done divided by time taken. So,

$P=\dfrac{W}{t}\\\\P=\dfrac{mgh}{t}\\\\P=\dfrac{m}{t}\times gh$

So,

$P=2400000\times 9.8\times 50\\\\P=1.176\times 10^9\ W$

Let there are n bulbs that could power 15 W LED. It can be calculated by dividing the power by 15. So,

$n=\dfrac{1.176\times 10^9}{15}\\\\n=78400000\ \text{bulbs}$

It means that the number of bulbs are 78400000.

How to make slime less sticky

topjm [15]

There are a few things you can do to make slime less sticky. You can either:
1) add a bit of baking soda (one to three tea spoons depending on how big it is, for the one that you show I would say one should be enough)
2)You can place it in hot water and squish the water out of it before placing it in cold water and then drying it out a bit with a towel. Don't forget to knead it a bit so it stays smooth and not too hard.
