It is possible for neutral objects to become charged by rubbing them together due to friction. Electrons of one object transfer to the other resulting to more electrons in the object than its protons therefore leaving it as charged. Hope this answers the question.
Answer:
Hydrosphere
Explanation:
One of the main components of Earth's interdependent physical systems is the hydrosphere. The hydrosphere is the sum of Earth's water, in the ocean, the ground, on the surface, and in the air.
We know, length of segment wave is half the wavelength .
Let, wavelength of wave is .
So, length of segment will be .
Now, it is given that the string vibrates in four segments.
So,
Speed can be given by :
Therefore, the wave speed in the string is 120 m/s.
From that particular short list, the item that best describes a plane
is the surface a flat table (or of any other flat thing).
-- The edge of a desk is a piece of a straight or curved line.
-- A curve in a road is a piece of a curved line.
-- The intersection of two walls is a piece of a straight line.
