The resistance between A and B is 10 ohms.
Answer:
There will be two forces acting on her: Gravitational force and Air resisitence
Answer:
0.5 eV
Explanation:
= Initial potential energy = 
= Final potential energy
= Initial width
= Final width = 
Energy of an electron in a one-dimensional trap is given by
From the equation we get
So,
The ground state energy will be 0.5 eV
Answer:
a) 
, b) 
Explanation:
a) The absolute pressure at a depth of 27.5 meters is:
b) The force exerted by the water is:
Answer:
B
Explanation:
Two atoms which are isotopes of one another must have a different number of neutrons.
Isotopes are defined as atoms of the same element which have the same numbers of protons i.e. atomic number remains the same, but has different numbers of neutrons. It is observed that they have same chemical properties due to the same electronic configuration but physical properties differs.
