Answer:
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

Answer:
Explanation:
We are given that
Amount of work needed to bring a point charge q0 from infinity to a point P=
We know that potential at point P=
Where U=Amount of work needed to bring a point charge q from infinity to a point P
Initially ,
New charge, q=
Then, work done,U=
Hence, the amount of work needed to bring a new charge 4q0 from infinity to point P=
Answer:
Explanation:
Answer:
The slits are 246 and 62 wavelengths wide, respectively.
Explanation:
Given that there are two slits:
the largest slit = x1 = 0.16mm or 0.00016m wide
the smallest slit = x2 = 0.04mm or 0.00004m wide, and
the wavelength of laser light = λ = 650nm or 650 × 10˄—9m
(a) the largest slit is X wavelengths wide where X = x1/ λ
Therefore, X = 0.00016m/650 × 10˄—9m = 246 wavelengths
(b) the smallest slit is X1 wavelengths wide, where X1 = x2/ λ
Therefore, Y = 0.00004m/650 × 10˄—9m = 62 wavelengths
