When light in air enters albite, it travels at a velocity of 1.95 × 108 m/s. What is albite’s index of refraction?

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y
