Your options are:
A) It is located at a distance of 2.6 million light years from Earth.
B) It has to travel a distance of 2.6 million kilometers to reach Earth.
C) It can be photographed by a space telescope in 2.6 million years.
<span>D) It has to move at the rate of 2.6 million kilometers per hour to reach Earth
You need to remember the definition of lightyear: one lightyear is the distance that light can travel in one year through space. It is a measure of astronomical distances and it is equal to 9.5×10¹²km.
Therefore, if light takes 2.6 million years to reach Earth, it means that the Andromeda Galaxy is at a distance of 2.6 million lightyears from Earth.
Hence, the correct answer is A) </span><span>It is located at a distance of 2.6 million light years from Earth.</span>
Answer:
2.84403 seconds
2.91483 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
It takes 2.84403 seconds to reach the highest point
The ball will travel 39.67431+2 = 41.67431 m while going down to the ground
The ball takes 2.91483 seconds to hit the ground after it reaches its highest point.
the measure of how many a wave passes on a certain point in a certain time is
frequency
Answer:
Answer for A
Explanation:
F1=GmM/r1^2
If r2 becomes r2=5r
F2=GmM/(25r^2)
Multiply with 25 gives to maintain the same force
I.e.,25F2=F1
F2=G(25m)M/25r^2=F1
By the factor 25 would change to increase to same.
The trade winds are located about 30 degrees north and south of the equator.
