I like to just keep writing them over and over on a page also if you remember them just before the exam than as soon as you start write them on the front of your test so you don’t forget them.
Hope this helps.
Answer:
An atom’s emission of light with a specific amount of energy confirms that electrons emit and absorb energy based on their position around the nucleus. The light emitted from an electron is a result of the electron's quantum jumps/leaps ( atomic electron transitions ) to and from different energy levels.
Answer:
8.45m/s = recoil speed
Explanation:
Momentum = mass • velocity
9.8kg • 88.03m/s = 102.1kg • recoil speed
862.694kg•m/s = 102.1kg • recoil speed
divide both sides by 102.1kg
8.45m/s = recoil speed
