Answer:
An atom which had neither gained any extra electron nor had lost any of its own electron is a Neutral Atom.
If an atom loses or gains one or more electron it becomes charged ie it becomes ion.
eg
Na is neutral atom with no charge
Ca+2 is an atom which has lost two electrons to become positively charged ion
O-2 is an atom which has gained two electrons to become negatively charged ion
<span>I of disk = 1/2MR² = (0.5)(230)(4.0)² = 1840 kgm²
I of disk-woman system = I = 1/2MR² + md² = (50)(4.0)² = 1840 + 800 = 2640 kgm²
L = Iw = (2640)(0.80)(2π) = 13,270 ≈ = 13,000 kgm²/s ANS
idk I'm just trying</span>
Answer:
7.2 as used in the equation
Answer:
Y_1 = 1.195 m = 119.5 cm
Explanation:
For nth order bright fringe, the distance from the center of the pattern is given by :-
Where,
n = order of nth bright fringe. = 1
wavelength of given light = 
D = distance between the screen and slits. = 3.4 m
and d = separation between the slits. 
Y_1 = 1.195 m = 119.5 cm
