If you treat an electron as a classical rigid sphere with radius 2.00×10−17 m and uniform density, what angular speed ω is necessary to produce a spin angular momentum of magnitude 3/4−−−√ℏ? use h = 6.63×10−34 j⋅s for planck's constant, recalling that ℏ=h/2π, and 9.11×10−31 kg for the mass of an electron. express your answer in radians per second to three significant figures. view available hint(s)

b mark me branliest thx

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
