If Aldebaran were to explode tonight then we will be able to see this explosion on the Earth in approximately 65 years. A light-year is a distance that light travels in one (1) year.
<h3>What is a light-year?</h3>
A light-year can be defined as a unit equal to the distance that light needs to travels in one (1) year on the Earth.
One light-year can be considered as a unit that equates to approx. 9.7 trillion kilometers (km) or 5.9 trillion miles.
In consequence, a light-year is a distance unit instead of a unit of time, and this unit was developed by Otto Ule.

Both balls land at the same time. If there is no air resistance they will both accelerate at the same rate and hit the ground at the same time with the same speed.
Answer:
The new gravitational pull would be three times as strong as the first which would be 0.000000003 or 3 × 10^-9N.
Explanation:
Hope this helps. . . <3
Answer:
Explanation:
As we know that the block of wood is suspended by spring
Now at equilibrium position we have net force balanced on it
so we have
so we will have
now the time period of the spring block system for one complete oscillation is given as
now plug in all values in it
Now total time to complete 3 cycles is given as
Answer:
Explanation:
From the question we are told that
Mass of first team man
Force of man first team man
Mass of second team man
Force of man second team man
Generally the equation for net force F_n is mathematically given by
Therefore the acceleration is given by
