Answer:
The total magnification will be 40x.
Explanation:
As we know if the magnification of the eyepiece of a microscope be and that of the objective be
, then the total magnification is given by
Given, and
Therefore total magnification is
Which plot correctly shows the velocity of the two balls as a function of time?
1 answer:
The given in this problem is that two balls are thrown at different times, different heights and velocities. A blue ball is thrown upward at a specific velocity at a lower altitude while a red ball is thrown downwards at a specific speed and at a higher height. In this case, we are asked here to describe the graph of the behavior of the balls as a function of time. The x-axis then is time while the y-axis is the velocity of the ball. The blue ball has a quadratic function while the red ball is more or less exponential. See the attached figure for reference.
