Answer:
Their velocity is 0m/s because the first box was only 10 kg and the second box was double the weight
-- Electrons are leptons. There are <em>three</em> electrons in each neutral Lithium atom.
The last two parts of the question are absurd.
-- Bonbons are candy, not atomic particles. A bonbon cannot fit into a Lithium atom.
-- A pentagon is a closed geometric figure that has five sides. Although you could, in principle, have a pentagon small enough to fit into a Lithium atom, you could never find a piece of paper small enough to draw it on.

Question: : A similarity between electromagnetic waves and matter waves?
----------------------------------------------------------------------------------------------------------------
Answer: electromagnetic waves are the combination of electric field and magnetic field and the matter wave related to dicrete particles. They are both waves (obviously), and both are made of particles which obey the equation E = hf. Where E is the energy of a particle and f is its frequency. Matter waves can move at varying speeds, and matter waves can be at rest. EM waves always move at c in vacuum.

False..
Explanation:
An electoMagnets attract iron due to the influence of their magnetic field upon the iron. ...
Answer:
Explanation:
Given that,
Initial speed, u = 5 m/s
Final speed, v = 10 m/s
Time, t = 2 s
The radius of the tire of the bike, r = 35 cm
We need to find the angular acceleration of the pebble during those two seconds. It can be calculated as follows.
So, the required angular acceleration of the pebble is equal to 
.
