Final answer:
The farthest man-made object from Earth is the Voyager 1 spacecraft, designed to study the outer planets and eventually interstellar space. As for the compression of the steel antenna, without the Young's modulus of steel, the exact amount of compression cannot be calculated.
Step-by-step explanation:
The name of the farthest man-made object from Earth is the Voyager 1 spacecraft. It was launched by NASA with the purpose of conducting up-close studies of Jupiter and Saturn, the conditions in the outer Solar System, and ultimately, to extend its mission to explore the boundaries of the Solar System and enter interstellar space.
In regards to the physics question about the compression of a steel antenna: To calculate the amount by which a 610-m high steel cylinder antenna of radius 0.150 m is compressed under a load of a physicist and equipment with a combined weight of 472 kg, we need to use the Young's modulus equation for steel.
However, the question does not provide the Young's modulus value for steel, and without it, an accurate calculation cannot be performed. In a typical scenario, you'd follow these steps:
- Calculate the force exerted by the physicist and equipment due to gravity (F = mg where m is mass and g is the acceleration due to gravity).
- Apply the formula for stress (Stress = Force / Area).
- Calculate the strain using the stress and Young's modulus for steel (Strain = Stress / Young's Modulus).
- Find the compression by multiplying strain by the original length of the antenna (Compression = Strain * Original Length).
Unfortunately, without the Young's modulus value, we cannot proceed to give a numerical answer.
