When a beam of light passes at an oblique angle into a material of lower optical density, the angle of incidence is
a. less than the angle of reflection.
b. less than the angle of refraction.
c. greater than the angle of reflection.
d. greater than the angle of refraction.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
