Answer:
the star collapses and the outer layers explode as a 'supernova'.
Answer:
No
Explanation:
tratar de justificar nuestras propias decisiones es algo totalmente innecesario, ya que todos tenemos derecho a tomar decisiones que en ocasiones pueden afectar indirectamente a otras personas y no hay nada de malo en ello.
Por otro lado, si está tomando una acción o tomando una decisión únicamente con la intención de afectar a otras personas, su acción no tiene justificación alguna.
First, you’re gonna need to know the basic formulas for velocity and acceleration. You’re also gonna need to know the kinetic formulas it seems like.
v = change in position/change in time
a = change in velocity/change in time
Vf = Vi + at
Vf^2 = Vi^2 + 2a*change in position
Xf = Xi + Vit + 1/2at^2
Question number 1 is just the velocity formula:
98m/10s = 9.8 m/s
Question number 2 also utilizes the velocity formula:
(250m-100m)/10s = 150m/10s = 15 m/s
Question number 11 uses the acceleration formula:
(15m/s - 25m/s)/2s = (-10m/s)/2s = -5m/s^2 now take the absolute value of that to get magnitude
Question number 12 uses the same concept as number 11. Assign a positive or negative sign respectively to the proper direction.
Number 3-10 use the kinematic formulas I mentioned. I’ll do number 3 for you. The mass of the car plays no factor in the distance traveled. We are given the initial velocity of the car, the acceleration of the car, and the final velocity of the car. It says it came to a rest, so that means 0m/s. The only time independent equation is the Vf squared one. Simply plug in the values and solve for the change in position.
0^2 = 20^2 + 2(-5)*(change in position)
0 = 400 - 10*(change in position)
-400 = -10*(change in position)
Change in position = 40 meters

Answer: 3.26 light years
Explanation:
Each star has a parallax of one arcsecond at a distance of one parsec, which is equivalent to 3.26 light years.
so the parallax of 1 arcsecond will be at a distance of <em>1/1 × 3.26 light years</em>
