Four pairs of objects have the masses as described below, along with the distances between
1 answer:
Answer:
<h2>Mass of 1 Kg and 2 Kg, 1 meters apart.</h2>Explanation:
The gravitational force is defined as
By definition, the gravitational force depends directly on the product of the masses and indirectly on the distance between the masses, which means the further they are, the less gravitational force would be. And, the greater the masses, the greater the gravitational force.
Among the options, the pair that would have the greatest gravitational force is Mass of 1 Kg and 2 Kg, with 1 meter between them.
Notice that the last choice includes the same masses but with a greater distance between them, that means it would be a weaker graviational force.
Therefore, the right answer is the second choice.

Answer:
From the question we are told that
The length of the rod is
The speed is v
The angle made by the rod is
Generally the x-component of the rod's length is
Generally the length of the rod along the x-axis as seen by the observer, is mathematically defined by the theory of relativity as
=>
Generally the y-component of the rods length is mathematically represented as
Generally the length of the rod along the y-axis as seen by the observer, is also equivalent to the actual length of the rod along the y-axis i.e
Generally the resultant length of the rod as seen by the observer is mathematically represented as
=>

=>
Hence the length of the rod as measured by a stationary observer is
Generally the angle made is mathematically represented
