Answer:
Different forces (including magnetism, gravity, and friction) can affect motion
Answer:
1.8m
Explanation:
Let the Elastics of the steel ASTM-36 
The strain of the bar when subjected to 150 MPa is

Therefore, if the bar elongates by 1.35 mm, then the original length L would be:

or 1.8m
1N=1kg•m/s^2 so the answer is 3N
Answer:
I'm pretty sure it's 37.5 joules of energy
Explanation:
hope this helps!
Explanation:
It is given that,
Uncertainty in the speed of an electron, 
According to Heisenberg uncertainty principle,

is the uncertainty in the position of an electron
Since, 



So, the uncertainty in its position is
. Hence, this is the required solution.
