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.
Answer:
a=positive
b=0
c=positive
d=negative
Explanation:
a=acceleration depends on the speed and time. if the speed and time are increasing at the same rate, the acceleration value will be positive as the vehicle is speeding up.
b=the speed and time are not increasing, therefore the vehicle is either stationary or travelling at a steady pace.
c=same explanation as a
d=the speed and time are not increasing at the same rate as the speed is decreasing. this means that the car is slowing down
Explanation:
The given number is 1.30x10-5. We need to convert it into scientific notation. We know that, any no can be written in this form as follows :
...(1)
m is any real no and n is any integer
If we compare the given no with equation (1), then, we found that m = 1.3 and n = -5.
It means that the given no is already in scientific notation. It can be written as :
Answer:
-30m
Explanation:
displacement = final position - initial position, or d = -20-10
