Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings
16 maybe it’s B I’m not sure
The wave is equation with the given conditions is y = 0.02 cos ( 0 )
<u>Given data</u>
period T= 25.0ms
speed of 30.0 m/s
t = 0
x = 0
transverse position of 2.00cm
speed of 2.0 m/s = v
<h3>writing the wave function </h3>
frequency f = 1 / T
f = 1 / 25
f = 0.04Hz
Angular velocity = ω = 2 * pi * f
ω = 2 * pi * 0.04
ω = 0.251
wave number K = ω / v
k = 0.251 / 2
k = 0.126
The wave equation
y = A cos ( kx + ωt )
this is equivalent to
y = 0.02 cos ( 0.126 * 0 + 0.251 * 0 )
y = 0.02 cos ( 0 )
