We are given a mercury atom in the ground state which absorbs 20 eV of energy. It is then ionized by losing an electron. We need to calculate the kinetic energy that the electron has after ionization.
The initial energy is 20 eV = 20 J/C
The electron charge is = 1.60217662 × 10-19<span> coulombs
To determine the kinetic energy, we can use this equation:
KE = 20 Joules / Coulombs * </span>1.60217662 × 10-19<span> coulombs
KE = 1.25x10^20 Joules
Therefore, the amount of kinetic energy that the electron has after ionization is </span>1.25x10^20 Joules or 1.25x10^17 kJ. <span />
Answer:
Value of angle between vector a and b is
.
Explanation:
Vectors a and b have scalar product 6.00
Let
be the angle between a and b.

ab cos
= 6 ...(1)
Vectors a and b have magnitude of vector product 9.00

ab sin
= 9 ...(2)
Dividing equation (2) by (1) we get

tan
= 1.5

= 
Thus, value of angle between vector a and b is
.
