Lenses are often coated with magnesium fluoride (refractive index n = 1.38) to reduce reflections. How thick should the layer of magnesium fluoride be if reflections from the coating surface interfere destructively with those from the coating-glass

An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its x-coordinate is 2.85 cm. If its x-coordinate 3.15 s later is - 5.00 cm, what is its acceleration?

How is a magnetic field generated?

When a bat uses echolocation to determine the distance to an insect, it sends out a sound wave and waits to see how long the sound takes to echo back. Suppose now that a bat hears its echo 0.06 LaTeX: ss after it emitted the sound.
