Explanation:
Given
mass of boy
mass of girl
speed of girl after push
Suppose speed of boy after push is
initially momentum of system is zero so final momentum is also zero because momentum is conserved
i.e. velocity of boy is 2.82 m/s towards west
Answer:
E=-1.51 eV.
Explanation:
The nth level energy of a hydrogen atom is defined by the formula,
Given in the question, the hydrogen atom is in the 3p state.
Then energy of n=3 state is,
Therefore, energy of the hydrogen atom in the 3p state is -1.51 eV.
Now, the value of L can be calculated as,
For 3p state, l=1
Therefore, the value of L of a hydrogen atom in 3p state is .
Answer:
a. The thickness of the wire is 2.5 mm.
b. The wire is 0.25 cm thick.
Explanation:
Number of turns of the wire = 10
The length of total turns = 25 mm
a. The thickness of the wire can be determined by;
thickness of the wire =
=
= 2.5 mm
Therefore, the wire is 2.5 mm thick.
b. To determine the thickness of the wire in centimetre;
10 mm = 1 cm
So that,
2.5 mm = x
x =
= 0.25 cm
The wire is 0.25 cm thick.
