Since the universe is infinite, the probability of events and reoccurrence is infinite. So that means that there is a chance, if

not 100% chance, that SOMEWHERE there is another earth, with another you, living the same life, at the same time. What are your thoughts about this??? thats so crazy to me

Two parakeets sit on a swing with their combined center of mass 10.0 cm below the pivot. At what frequency do they swing?
Oksanka [162]

Answer:

1.58 Hz

Explanation:

The frequency of the simple pendulum is given by

f = 1/T

 = 1/2π√g/l  

In this problem, I = 10.0 cm = 0.1 m  

f = 1/2π√9.8/0.1

=  1.58 Hz

Thường ngày an đi bộ từ nhà đến trường mất 15 phút biết quãng đường từ nhà đến trường dài 1.5 km tính vận tốc đi thường ngày của
DedPeter [7]

Answer:

Speed in kilometer/hour = 6 kilometer / hour

Explanation:

Given;

Time taken to cover distance = 15 minute = 15 /60 = 0.25 hour

Distance of school = 1.5 kilometer

Find:

Speed in kilometer/hour

Computation:

Speed in kilometer/hour = Distance / Time

Speed in kilometer/hour = Distance of school / Time taken to cover distance

Speed in kilometer/hour = 1.5 / 0.25

Speed in kilometer/hour = 6 kilometer / hour

andre [41]
I believe the correct answer from the choices listed above is the second option. With this information, he was able to conclude that the beam was negatively charged. His cathode ray<span> tube experiments led to a very important scientific discovery, the electron. Hope this answers the question.</span>

Which would show an example of how physical changes are reversible? cutting a gold bar in two pieces and then putting the pieces
arlik [135]

Melting tin and then cooling it into a mold is an example of reversible physical changes.

<u>Explanation:</u>

         When an object undergoes a change in size, state, or shape and not in their chemical compositions referred to as physical change. But chemical change occurs as a result of the change in substances composition. It also forms a new one by the combination/ breakage of one or more objects.

         In the case of making gold cube into two pieces, there is no possibility of getting the original state again even the physical change happens. Match burning and relighting and sodium plus chlorine forming table salt show chemical change. But in tin melting and cooling it to form mold is the physical change i.e changes in state(liquid to solid) and are reversible too.
