True because The Eye Wall of a hurricane's most devastating region. Located just outside of the eye is the eye wall. This is the location within a hurricane where the most damaging winds and intense rainfall is found. At the surface, the winds are rushing towards the center of a hurricane forcing air upwards at the center.
Answer:
E₁ = 1.042 eV
E₄₋₃= 7.29 eV
E₄₋₂= 12.50 eV
E₄₋₁= 15.63 eV
E₃₋₂= 5.21eV
E₃₋₁= 8.34eV
E₂₋₁= 3.13eV
Explanation:
The energy in an infinite square-well potential is giving by:
<em>where, h: Planck constant = 6.62x10⁻³⁴J.s, n: is the energy state, m: mass of the electron and L: widht of the square-well potential </em>
<u>The energy of the electron in the ground state, </u><u>n = 1</u><u>, is: </u>
The photon energies that are emitted as the electron jumps to the ground state is the difference between the states:





Have a nice day!
Explanation:
Ohms law states that the electrical current present in a metallic conductor is directly proportional to the potential difference between the metallic conductor and inversely proportional to the resistance therefore if the voltage is increased resistance also increases provided that temperature and other physical properties remains constant V=IR
Answer:
the crown was not made of pure gold
Explanation:
Mass of gold = weight in air/ g = 7.84N/10ms-2= 0.784 Kg or 0.8Kg
From Archimedes principle:
Upthrust= weight in air- weight in a fluid
Upthrust= volume × density × g
Note density of water = 1000kgm-3
7.84-6.84= V × 1000kgm-3×10ms-2
V= 1/10000= 1×10-4 m^3
Density = mass/ volume= 0.8/1×10-4
= 8×10^3 Kgm-3
But we know the density of gold to be 19.3 ×10^3 kgm-3
Hence the crown was not made of pure gold
