field is force at a distnce = falling under grav ... contact is force at point of contact
Answer:
Surface tension is a fundamental property of the surface of liquid. Surface tension is responsible for the curvature of the surfaces of air and liquids. Surface tension is responsible for the ability of some solid objects to “float” on the surface of a liquid.

Answer:
Explanation:
The time taken by a transverse wave to propagate from one end to another depends on the number of oscillation made by the wave itself. If the total number of oscillation of the wave is known, the time taken by the wave to propagate through can be determined.
Note that the term "period" is the time taken by a transverse wave to complete one oscillation. So if we know the number of oscillation made in one second by the wave and the total oscillation made, then we can know determine how long it will take a transverse wave to propagate from one end of the string to the other
I believe the correct answer is C good luck!
Answer:
The value is 
Explanation:
From the question we are told that
The amount of power delivered is 
The time taken is 
The wavelength is 
Generally the energy delivered is mathematically represented as
Where 
is the Planck's constant with value 
c is the speed of light with value 
So
=>
