Your answer is going to be 2m south
The correct option is C.
J.J Thompson demonstrated that Dalton's model of the atomic theory was wrong by showing that atoms are made up of sub particles, this is contrary to the report that Dalton gave about atoms. In his experiment, Dalton reported that atoms are indivisible, that is, they can not be broken down into smaller particles. J.J Thompson on the other was able to show through his cathode ray experiment that atoms are made up of smaller particles called electrons.
FORMULA:
ANSWER:
We are given with mass of car 394kg and velocity of car 15m/s.
Plugging the respective value,
- K.E. = 1/2 × 394 × 15²
- K.E. = 197 × 225
- K.E. = 44,325J
The energy-level change occurs as the atom is absorbs a 2.03-eV photon.
<h3>
Energy change of the mercury atom</h3>
The energy change of the mercury atom is calculated as follows;
Energy emitted by a photon when it falls from level b to energy level e is calculated as follows;
ΔE = -3.71 eV - (-5.74 eV)
ΔE = -3.71 eV + 5.74 eV
ΔE = 2.03 eV
When electron jumps from lower energy level to higher energy level, energy is absorbed, thus, the energy-level change occurs as the atom is absorbs a 2.03-eV photon.

False because that would not matter cause we all weigh different weights
