Answer:
The formula for kinetic energy is K.E. = 1/2 mv 2 , where "m" stands for mass and "v" stands for velocity. Kinetic energy is typically measured in units of Joules, and 1 Joule is equal to 1 kilogram-meters squared per second squared.
Explanation:
Car B, Car C, And Car E Are either speeding up or slowing down
Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by
here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that 
Potential well dimension = 
Mass of electron 
So energy required to electron to jump from ground state to 3rd state



Because glass is not a good heat conductor. What it means is that heat isn't transfered through its structure as quickly as it would with metal, for instance. Because heat can't penetrate glass as quickly, the contents stay at the same temperature for longer.
