Answer:
a) their amplitudes are the same their phase difference is constant their frequencies are the same
Explanation:
Coherent waves are the waves that have constant phase difference, equal frequency, amplitude and waveform.
Frequency denotes the number of cycles a wave completes in one second.
Amplitude is the maximum height that the wave reaches.
Waveform is the two dimensional representation of a wave in graphical form.
No net force acts on it.example is the earth
Answer:
M_e = 6.04 * 10^24 kg
Explanation:
Given:
- The time period of moon orbit T = 27.32 days
- Distance from center of earth to moon r = 238,910 miles
- The gravitational constant G = 6.67408 * 10^-11
Find:
- Determine the mass of the earth
Solution:
- The mass of earth as a function of time period T and radius of orbit r is related by an expression as follows:
M_e = (2*pi / T)^2 * (r^3 / G)
M_e = (2*pi / 27.32*24*60*60)^2 * (238910*1609 / 6.67408 *10^-11)
M_e = 6.04 * 10^24 kg

The initial velocity of particle is 7.568 m/s
Given:
Acceleration = a = 6.14 m/s2
Time = t = 0.300 s.
final velocity = v = 9.41 m/s.
To Find:
initial velocity = u
Solution: Velocity is the prime indicator of the position as well as the rapidity of the object.
v = u + at
u = v - at = 9.41 - 6.14*0.3 = 7.568 m/s
Hence, initial velocity of particle is 7.568 m/s
