Answer:
7.99 × 10⁸ atoms
Explanation:
The diameter of Molybdenum atom is 418pm = 0.000000000418m
therefore to determine number of Mo Atoms that'll be required =
0.334 ÷ 0.000000000418 = 7.99 × 10⁸ atoms
Mass of one Mo atom = 1.59×10⁻²² g
Mass of 7.99 × 10⁸ atoms that'll be required = 1.59×10⁻²² × 7.99 × 10⁸ =
12.7041 × 10⁻¹³g.
Answer:
Explanation:
for the calculation of the electric potential inside a parallel plate capacitor you can use the formula for the electric field inside the capacitor.
where d is the distance between plates and E is the electric field, which is given by:
By replacing you obtain:
where Q is the charge stored by the capacitor and A is the area of the plates.
hence, the answer is Qd/Ae0
Answer:
4. Becomes softer as temperature rises
Explanation:
An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.
Answer: 9 Kg
Explanation:
Force = Mass x Accelaration
18 = Mass x 2
Mass = 18/2
Mass = 9 Kg
