Answer:

Explanation:
Given that,
The uncertainty in the position of an electron along the x-axis is, 
We need to find the east uncertainty in any simultaneous measurement of the momentum component of this electron.
We know that the Heisenberg's uncertainty principle gives the relation between the uncertainty in position and the momentum of electron as :

Putting all the values, we get :

So, the momentum component of this electrons is greater than
.
There are 92 elements that are found in nature. Roughly 80 of those are capable of combining with each other to make compounds, so there are a lot more than 92 compounds.
Example: Take carbon and hydrogen. (please)
Carbon and hydrogen combine to make methane, ethane, propane, pentane, hexane, heptane, octane, butane, and several more 'tanes'.
And if you have some oxygen along with the carbon and hydrogen, you can
make all the alcohols there are, plus vinegar.

Answer:
28 cm and 32 cm
Explanation:
1. The spring pendulum hangs vertically, oscillates harmonic with amplitude 2cm and angular frequency 20 rad/s. The natural length of
a spring is 30cm. What is the minimum and maximum length of the spring during the oscillation? Take g = 10m/s2.
As the amplitude is 2 cm and the natural length is 30 cm. So, it oscillates between 30 -2 = 28 cm to 30 + 2 = 32 cm.
So, the minimum length is 28 cm and the maximum length is 32 cm.
Many ways for example they look up related things and study them or they can test it and see what happens
