Physics

Question 1

atmospheric pressure formula

Answer 1

densityaccerlerationheight

Question 2

myopia (nearsightedness)

Answer 2

eye forms an image of distant objects at a focal point in front of retina
corrected with diverging concave lens

Question 3

hyperopia (farsightedness)

Answer 3

can’t see nearby objects. Corrected by placing converging convex lens in front of eye

Question 4

polarization

Answer 4

alignment of transverse wave oscillations in a particular orientation along the x,y,z, axis
transverse waves cause oscillations perpendicular to the direction of propagation

Question 5

wavelength for one open one closed pipe + both closed pipes

Answer 5

wavelength = 4*L/n
n= odd numbers only

Question 6

frequency +wavelength for waves in open pipes and strings

Answer 6

f=velocity/wavelength
=n*v/2L
wavelength: 2L/n

Question 7

lens equation

Answer 7

1/focal length= 1/object +1/image

converging (convex): positive
diverging (concave): negative F=-f

Question 8

conductors vs insulators

Answer 8

conductors facilitate electrical current whereas insulators inhibit electrical current
