Its tangential speed is constant although its velocity is changing. As the object changes direction, it results in a changing of positive and negative signs of the velocity. Although, the magnitude of the velocity (speed) is not changing.
They almost entirely reside within galaxies because quasars are a subset of blackholes with a large and fast enough accretion disk to generate a beam of interstellar material perpendicular to itself. This typically only occurs in the largest black holes at the center of galaxies (supermassive blackholes) or at least stellar black holes---which still occur within galaxies because the material is necessary to form them.
Hope this helps! Please mark as brainliest!
<span>Using Coulomb's law: k*(-0.3)*(-0.3)/(d^2)=19.2
D is the distance between the two negative charges</span>
Formulas are:
h = g t² / 2
x = v x * t
7 m = 9.81 m/s² * t² / 2
t² = 14 : 9.81
t² = 1.427
t = √1.427 = 1.19 s
x = 0.2 m/s * 1.19 s
x = 0.24 m
Answer: The ball lands 0.24 m from the base of the building.
