Answer:
1 ohm
Explanation:
since there are two identical resistors, one resistor will be
R = 
=2ohm [ proven as in series 
]
to calculate the equivalent resistance when in parallel:
so,
Answer:
all qn 1,2,3 have same answer ,. Yes,. hope it helps
Answer:
46.67 N/m
Explanation:
mass, m = 0.1 kg
distance, y = 2.1 cm = 0.021 m
Let K be the spring constant.
F = mg = Ky
0.1 x 9.8 = K x 0.021
K = 46.67 N/m
Thus, the spring constant of the spring is 46.67 N/m.

3. The nuclear potential that binds protons and neutrons in the nucleus of an atom
is often approximated by a square well. Imagine a proton confined in an infinite
square well of length 10−5 nm, a typical nuclear diameter. Calculate the wavelength
and energy associated with the photon that is emitted when the proton undergoes a
transition from the first excited state (n = 2) to the ground state (n = 1). In what
region of the electromagnetic spectrum does this wavelength belong?
Answer 3
We are given that,
Length of square well = L = 10−5
nm = 10−14 m.
Energy of proton in state n is given by,
