The largest refracting telescope in the world is at yerkes observatory in wisconsin. the objective lens is 1.02 in diameter and has a focal length of 19.4 . suppose you want to magnify jupiter, which is 1.38×105 in diameter, so that its image subtends an angle of (about the same as the moon) when it is 6.28×108 from earth.
a) what focal-length eyepiece do you need?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
