One scientist did an experiment with a coin. The steps of the experiment are listed below. Place a coin on a table at a distance of about 1 meter from the eyes. Hold up one finger and use it to cover the coin from the line of sight. Without moving the finger, close one eye. Observe that the coin appears to shift and come into the line of sight. Estimate the approximate distance by which the coin shifts. Repeat steps 2, 3, 4, and 5 by placing the coin at distances of 50 cm and 25 cm. Based on the experiment, what would the scientist most likely conclude about the parallax method of measurement of star distances? parallax shift remains the same at all distances of stars from Earth parallax shift depends on the size of the stars with respect to Earth parallax would be most effective in measuring distances to stars which are very far away from Earth parallax would be most effective in measuring distances to stars which are close to the Earth
