Answer:
18931.4
Explanation:
Given : velocity of the electron = 2.0 10
mass of the electron = 9.19 103
we know that reduced planks constant, h = 6.5821 eV s
We know from uncertainity principle,
= 18931.4 m
Hence, uncertainty in position of the electron is 18931.4
Entropy change of hot and cold reservoir are -0.08333 kJ/k and 0.16666 kJ/k respectively.
<u>Explanation</u>:
Given:
Temperature at hot reservoir,
Temperature at cold reservoir,
Amount oh heat transferred,
Entropy change at hot reservoir,
Entropy change at cold reservoir,
Total entropy change,
is not less than zero.Hence,it fulfills increase of entropy principle.
Answer:
I = 4.642 Ampere.
x = 2.145 cm
Explanation:
a) As we know, the magnetic field on the axis of the loop is given as
where a = radius of loop
x = point on the axis of loop
N = No of turns of coil
Current in the loop for which the magnetic field at the center is 0.0750 Tesla is given as x = 0
Therefore, the above equation can be rewritten as
I =
by putting values
I =
Current in the loop for which the magnetic field at the center is 0.0750 Tesla = I = 4.642 Ampere
b)
Now for part b the magnetic field at a distance x from the center is given as
multiply and divide by a on both sides we get
As we know, according to Biot sivorts law,the Magnetic Field at the Center of a circular loop is given as
( Magnetic field at center) =
So we got magnetic field at any point x as
= X
For magnetic field at x is half of the B at center
=
from the above two equations
=
Putting a = 2.80 cm
We have x = 2.145 cm Ans
μ
It is given that volume is constant i.e 3000 L.
So,
Now,
Putting all values in above equation, we get :
Therefore, the new pressure will be 23.20 MPa.
Hence, this is the required solution.
