A human hair is approximately is 50um in diameter. express this diameter in meters

stealth61 [152]

50 μm = 5 × 10⁻⁵ m in diameter

<h3>Steps</h3>

1μm = 1 x $10^{-6}$ m

<h3>Given</h3>

1μm = 1 x $10^{-6}$ m

50μm = 50 x $10^{-6}$ m

50μm = 50 x 10 x $10^{-6}$

50μm = 5 x $10^{-5}$ m

<h3>Conclusion</h3>

A human hair is approximately 50 μm = 5 × 10⁻⁵ m in diameter

<h3>How big is a human hair on average?</h3>

between 17 and 181 micrometers

The typical diameter of human hair can range from 17 micrometers to 181 micrometers, according to research. Using 50 micrometers as an average figure for its diameter, this translates to 50,000 nanometers.

<h3>What is a human hair's diameter in inches?</h3>

The finest hair is flaxen, with a diameter ranging from 1/1500 to 1/500 of an inch. the coarsest hair is black, measuring between 1/450 and 1/140 of an inch.

Coherent light that contains two wavelengths, 660 nm (red) and 470 nm (blue), passes through two narrow slits that are separated

WITCHER [35]

Answer:

0.002699 m or 2.699 mm

Explanation:

y = Fringe distance

d= Distance between slits = 0.310mm

L = Screen distance = 4.40m

λ= Wavelength

Given from question

λ₁= 660 nm = 6.6 x 10^-9 m

λ₂= 470 nm = 4.7 x 10^-9 m

d = 0.340 mm = 3.4 x 10^-3 m

L = 4.40 m

In the case of constructive interference, we use below formula

y/L = mλ/d

For first order wavelength

(y₁/4.40) =(1×660x10⁻⁹)/(0.310*10⁻³)

y₁= (0.310*10⁻³)×(4.40)/(0.310*10⁻³)

y₁=0.00937m

(y2/4.40) =(1×470x10⁻⁹)/(0.310*10⁻³)

y2= =(1×470x10⁻⁹)×(4.40)/(0.310*10⁻³)

y2=0.00667m

distance between the fringes is given by (y₁ -y2)

=0.00937-0.00667=0.002699m

Therefore, distance on the screen between the first-order bright fringes for the two wavelengths is 0.002699 m or 2.699 mm

Question 5 (1 point)

Sophie [7]

Main answer- the velocity of 2.2kg ball is 12.566m/s

supporting answer- In circular motion the velocity is termed as angular velocity

Angular velocity represents the rate of variation of an object's position angle with respect to time.

W =theta/ time

W = length of the arc/ radius of circle × time

body of the answer-2πr/r×t =2π/t

2×π/ 0.5 = 12.566 m/s

final answer- hence the velocity of ball is revolving is 12.566 m/s
