Answer:
b is the correct answer i believe
Explanation:
the strong nuclear force encourages particles to come together so that they can nuetralize, a process the opposite of the electrostatic force of repulsion. This lets the atom stay intact because if the repulsion was more than the nuclear forces strength the atom would lose electrons and slowly decay
The correct answer would be 16m/so
Answer:
Explanation:
frequency of radiation
= 8.54 x 10¹⁴
wave length = 3 x 10⁸ / 8.54 x 10¹⁴
= .3513 x 10⁻⁶ m
= 3513 A
Energy of this wave OR energy of each photon in eV
= 12375 / 3513
= 3.52 eV
the minimum amount of energy required = 3.52 eV.
A pure substance is a substance that contains only one type of atom or molecule. Homogeneous mixture is commonly referred to solution as there is uniform distribution all over the mixture while in a heterogeneous mixture consists of different phases or substances that are visible.
A compound is substance containing two or more elements that are chemically bound together. Therefore, coleslaw (a salad containing finely shredded cabbages and carrots and a creamy dressing) is a heterogeneous mixture.
Answer:
Volume charge density: When the charge density is throughout the volume of a body, then the charge per unit volume is called volume charge density and it is represented by ρ.
∴ρ=
Hence the unit of ρ is Cm
−3
Example: If a charge q is uniformly distributed in the whole volume of a
sphere of radius R, then p =
=3q/4πR-3
