Which wave has the greatest amplitude?
2 answers:
Explanation:
The maximum displacement of the particles of wave is called its amplitude. The amplitude of purple wave is greatest i.e. wave A
The energy of wave is directly proportional to the square of amplitude. So, the purple wave carries the most energy i.e. wave A.
The number of oscillations or vibrations per unit time is called frequency of wave. The frequency of blue wave is largest i.e. wave C
The distance between two consecutive crests or two troughs is called the wavelength of wave. Wavelength and frequency have inverse relationship. So, the wavelength of blue wave is smallest i.e wave C

Answer:
Explanation:
The formula for this is
where F is the gravitational force, G is the gravitational constant, m1 is the mass of one object and m2 is the mass of the other object. We are looking for r, the distance between the centers of their masses.
Filling in:
and moving things around to solve for r:
Doing all that and rounding to the 3 sig fig's you need gives us a distance of 1.55 m
