Well, the surface of still water has surface tension. If there isn't enough mass or weight to break the surface tension, the object will float.

Use the passage to answer the question.
Studentka2010 [4]

This is not something that waves do because they need a medium to travel through, while particles do not.

<h3>How light travels in space?</h3>

A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.

So we can conclude that electromagnetic waves like light do not require medium for its propagation.

A proton moving at 5.00 106 m/s through a magnetic field of magnitude 1.78 t experiences a magnetic force of magnitude 7.40 10-1
aliya0001 [1]

The magnetic part using the Lorentz force is: F = q v x B, 
where v and B are vectors and v x B is the vector cross product. 

Magnitude of the force: F = q v B sin(α) 

So, sin(α) = F/( e v B), with e the proton charge. 

This will give you a value for sin(α), and two potentials for its opposite.

You will now look for: 

sin(α) = 7.40 10^-13/( 1.60 10^-19 * 5 10^6 * 1.78) 
= 0.520


So either sin(α) = 0.502 or sin(α) = -0.502 
The 1st α = 30.1 degrees or α = 150 degrees. 
The 2nd α = 210 degrees or α = 330 degrees. 
So we can say that 30.1 degrees and 330 degrees would be minimum and biggest on [0,360]
