V= s/t = 400/4.5=800/9 (km/h)
The acceleration due to gravity is 9.81m/s^2
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>
Complete Question
A small block is released from rest at the top of a frictionless incline. The distance from the top of the incline to the bottom, measured along the incline, is 3.40 m. The vertical distance from the top of the incline to the bottom is 1.09 m. If , what is the acceleration of the block as it slides down the incline plane
Answer:
The acceleration is
Explanation:
From the question we are told that
The distance from top to bottom of the inclined plane measured along the incline is
The distance from top to bottom of the inclined plane measured along the vertical axis is
According to the SOHCAHTOA rule
=>
substituting values
=>
T
The acceleration of a block on a frictionless inclined plane is mathematically represented as
substituting values
