How is sound produced in our throat

1 answer:

4 0

In humans sound is produced by the voice box or the larynx.

The voice box is at the upper end of the wind pipe.

Two vocal cords are stretched across the voice box in such a way that it leaves a narrow slit between them.

Air passes through these slits. When air from lungs is forced out through the slit, the vocal cords vibrate to produce sound.

Help!<br> Is it possible for a child to have genetic material identical to one parent? Explain.

bagirrra123 [75]

No, you may have similar genetic material but not identical. You can have identical genetic material to your brother or sister if they are identical to you but not your parent because your genetic material consists of two people who have no relation to each other genetic material wise.

Two small plastic spheres are given positive electrical charges. When they are 16.0 cm apart, the repulsive force between them h

Drupady [299]

Answer:

q = 7.542 x 10⁻⁷ C = 754.2 nC

Explanation:

The Coulomb's Law gives the magnitude of the force of attraction or repulsion between two charges:

F = kq₁q₂/r²

where,

F = Force of attraction or repulsion = 0.2 N

k = Coulomb's Constant = 9 x 10⁹ N m²/C²

r = distance between charges = 16 cm = 0.16 m

q₁ = magnitude of 1st charge

q₂ = magnitude of 2nd charge

Since, both charges are said to be equal here.

q₁ = q₂ = q

Therefore,

0.2 N = (9 x 10⁹ N m²/C²)q²/(0.16 m)²

(0.2 N)(0.16 m)²/(9 x 10⁹ N m²/C²) = q²

q = √(5.88 x 10⁻¹³ C²)

A simple pendulum consisting of a bob of mass m attached to a string of length L swings with a period T. If the bob's mass is do

Alborosie

1. B. T

The period of a simple pendulum is given by:

$T=2\pi \sqrt{\frac{L}{g}}$ (1)

where

L is the length of the pendulum

g is the gravitational acceleration

From the formula, we notice that the period of the pendulum does not depend on the mass of the bob. Therefore, when the bob's mass is doubled, the period does not change.

2. C: sqrt(6)*T

In this case, the pendulum is brought to the moon, where the gravitational acceleration is

$g'=\frac{g}{6}$

If we substitute this value into the equation for the period (1), we find the new period of the pendulum:

$T'=2\pi \sqrt{\frac{L}{g'}}=2\pi \sqrt{\frac{L}{(g/6)}}=\sqrt{6}(2\pi \sqrt{\frac{L}{g}})=\sqrt{6} T$

3. B: It will no longer oscillate because there is no gravity in space

Explanation:

The motion (oscillation) of the pendulum is caused by the force of gravity, which "pulls" the bob towards the equilibrium position. If there is no gravity, then there is no force acting on the bob, therefore the pendulum can no longer oscillate.

So, the correct answer is

B: It will no longer oscillate because there is no gravity in space

An asteroid has acquired a net negative charge of 149 C from being bombarded by the solar wind over the years, and is currently

bearhunter [10]

Answer:

93.125 × 10^(19)

Explanation:

We are told the asteroid has acquired a net negative charge of 149 C.

Thus;

Q = -149 C

charge on electron has a value of:

e = -1.6 × 10^(-19) C

Now, for us to determine the excess electrons on the asteroid, we will just divide the net charge in excess on the asteroid by the charge of a single electron.

Thus;

n = Q/e

n = -149/(-1.6 × 10^(-19))

n = 93.125 × 10^(19)

Thus, it has 93.125 × 10^(19) more electrons than protons
