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.

A baseball has a momentum of 6.0 kg m/s south and a mass of 0.15 kg. What is the baseball’s velocity? Show work
kupik [55]

Momentum of an object is defined as product of mass and velocity

so it is given as

P = m* v

here it is given that

mass = 0.15 kg

momentum = 6 kg m/s

so by plug in values in the above equation

6 = 0.15 * v

v = \frac{6}{0.15}

v = 40 m/s

so its speed will be 40 m/s

Given that the velocity of blood pumping through the aorta is about 30 cm/s, what is the total current of the blood passing thro
TiliK225 [7]

Answer:

94.248 g/sec

Explanation:

For solving the total current of the blood passing first we have to solve the cross sectional area which is given below:

A_1 = \pi R^2\\\\A_1 = \pi (1)^2\\\\A_1 = 3.1416 cm^2

And, the velocity of blood pumping is 30 cm^2

Now apply the following formula to solve the total current

Q = \rho A_1V_1\\\\Q = (1)(3.1416)(30)\\\\

Q =  94.248 g/sec

Basically we applied the above formula So, that the total current could come
