The lab experiment is repeated again with the same two glass plates and the same sodium lamp but with a different human hair. Th

OleMash [197]

Answer:

diamerer of the hair (t) 3.11 X 10^{-5} m

Step-by-step explanation:

The first dark spot is at the zero location where the glass plates touch. To find the number of dark fringes after first dark fringe, divide 12 cm by 0.75 mm (.075 cm)

12/.075 = 160.0

total number of additional bright fringe is 156 because there is no further portion for extra dark fringe.

diamerer of the hair (t) can be derived as

2nt = (m + .5)*wavelength

2(1.52)(t) = (160.5)(589.3 X 10^{-9})

t = 3.11 X 10^{-5} m

Jojo likes to paint. She estimates the number of paintings she completes using the function P of w equals two thirds times w min

pantera1 [17]

Answer:

$P = \frac{2}{3} [J(y)] - 2$

Step-by-step explanation:

If Jojo completes P number of paintings working w weeks then the relation between P and w is given by $P = \frac{2}{3} w - 2$ . ........ (1)

Again, the function J(y) represents how many weeks per year she spends painting.

So, w = J(y). ...... (2)

Therefore, the composite function which represent how many paintings Jojo completes in a year, is given by

$P = \frac{2}{3} [J(y)] - 2$ (Answer)

Nookie1986 [14]

Answer:

D: 768

Step-by-step explanation:

First, he divides a piece of paper in half.

$1 \div \frac{1}{2} = 2$

He gets two pieces.

Next, he cuts each of the pieces into three parts.

$2 \div \frac{1}{3} = 6$

Thirdly, he cuts each of the 6 pieces into 8 pieces.

$6 \div \frac{1}{8} = 48$

Lastly, he divides each piece into 16 parts.

$48 \div \frac{1}{16} = 768$

He has 768 pieces in the end. (D)
