Explanation:
Throughout this chapter, we have been studying traveling waves, or waves that transport energy from one place to another. Under certain conditions, waves can bounce back and forth through a particular region, effectively becoming stationary. These are called standing waves.
Choice-D is the correct statement.
Answer:
Mass of banana is
Kg
Explanation:
Step 1: Determine the equation of speed of an object moving in an harmonic motion
Speed of moving in an harmonic motion is given by

Here, v represents the speed of the object in harmonic motion, k is the springs constant, m is the mass of the object, A is the amplitude, and x is the position.
In this question ,
because only at this position maximum speed occurs
So the simplified equation becomes -

OR

Substituting the given values in above equation we get -
Assume spring constant is
N/m

Mass of banana is
Kg
Brown dwarf is the first box
White dwarf is the second box
Black dwarf is the third box
Red giant is the fourth box
And
Black hole is the last box
