To reduce friction between two surfaces, you have to
make the surfaces smoother.
The best way to do that is to introduce a fluid between them,
like grease, oil, or air.
work is force x distance = 25 x 0.4
= 2.5x4 = 10joules
pwer would be 10j/2s watts .... 5 watts
I don’t worry wewwwww it is a good time to get it done lol lol i don’t worry about it lol lol i lol
Answer:
c. probablistic view of nature.
Explanation:
According to the problem of particle in a box in one dimension. If the particle energy E is taken less than the height of the barrier V.
Then with the help of classical mechanics it can be prove that the particle can not cross the barrier but according to the quantum mechanics, there is a small but a finite probability to cross the barrier.
Therefore by the above discussion it can be concluded that quantum mechanics can be thought as a probablistic view of nature.
Answer:
The value is 
Explanation:
Generally the moon's radial acceleration is mathematically represented as
Here 
is the angular velocity which is mathematically represented as
substituting 
for T(i.e the period of the moon ) we have
=> 
From the question r(which is the radius of the orbit ) is evaluated as
substitute 
for R and 
H
=> 
So
