Answer: The atomic mass of a Europium atom is 151.96445 amu.
From the given information:
Percent intensity is 91.61% of Europium atom of molecular weight 150.91986 amu.
Percent intensity is 100.00% of Europium atom of molecular weight 152.92138 amu.
Abundance of Eu-151 atom:
Abundance of Eu-153 atom:
Atomic mass of Europium atom:
Therefore, the atomic mass of a Europium atom is 151.96445 amu.
I found this in a physics tab, I do t know why.
But your answer sir/ma’am is skeleton
Explanation:
d) Magnetic force is the power that pulls materials together (magnet e. g iron)
an example :how magnet can pick up a coin.
e) frictional force produces when two surfaces are in contact with each other.
effects of friction : I) it produces heat
II) it causes loss in power.
It’s B i literally jus learned this
Answer:
16.25 m
Explanation:
we know that the equation pf parabola
from bellow figure the coordinate of parabola is (600,65) that is y=600 and x=65
putting the the value of y and x in the equation of parabola
k=0.0001805
now the equation is
we have to find the value of y at x=300m
so 
y=16.25 m
