The initial curvature and other settings of the mirrors on the Hubble did not produce good images. Space shuttle missions replaced/corrected the mirrors to give clear images.
General formula for emf is : emf = vBL (sin 0)...(1)
As the angle here is 90º and sin90º =1.
So, equation (1) becomes : emf = vBL Putting values :
emf = (6.2)(1.5)(3.96 * 10<span>^-3) = 0.0369 volts

Kepler's work revealed that the orbit of each planet is an ellipse,
with the sun at one focus.
Newton's work revealed that if his law of universal gravitation is
correct, then the orbit of each planet must be an ellipse with the
sun at one focus.
It is a physical change, as only the dimensions changed, not the chemical structure.
