In the lungs there are tiny sacs of air, which are called alveoli. an oxygen molecule is trapped within a sac, and the uncertainty in its position is 0.12 mm. what is the minimum uncertainty in the speed of this oxygen molecule?

Answers

Answer 1

Answer:

As we know that Heisenber's uncertainty law gives that

$\Delta x * \Delta P = (h)/(4\pi)$

here we know that

$\Delta x = uncertainty In Position = 0.12 mm$

$\DeltaP = uncertainty In Momentum = m*v$

now from the above formula we will have

$0.12 * 10^(-3)* 32*10^(-3)v = (h)/(4\pi)$

$3.84*10^(-6)*v = (6.6*10^(-34))/(4\pi)$

$v = 1.37 * 10^(-29)m/s$

so above is the uncertainty in the speed

A coil of insulated wire is wound many times around an iron bar. The wire is connected to a battery and a contact switch. The contact switch is alternately flipped closed and left closed, so the wire carries a current through it, and then flipped open and left open, so that the current stops. Describe what magnetic fields are created, if those magnetic fields in turn induce an emf, and whether the induced emf is in the direction of the original current or opposite to it. Justify your answer using Lenz's law and the conditions which can cause a magnetic field to induce an emf. You may draw a diagram if it helps you to visualize the apparatus.

How to find the time in the air based off of the height and velocity

Answers

Answer:

To find time to reach maximum height given initial velocity use the equation Vf=vi+at. At the maximum height, the object has no initial velocity left and therefore you can substitute 0 for the Vf in the equation.

What is the main difference between a longitudinal wave and a transverse wave? a longitudinal wave travels faster than a transverse wave. a transverse wave always has a larger amplitude than a longitudinal wave. the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave. the frequency is directly proportional to wavelength in a longitudinal wave but inversely proportional in a transverse wave.?

Answers

When waves propagate in a medium, then the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

What are sound waves?

A sound wave is caused by disturbances in the path of propagation of the particles. These disturbances can be caused in the medium like solid, liquid, and air.

There are two main types of waves namely - Transverse waves and longitudinal waves.

Transverse Waves - These waves are the waves where the particles in a medium travel perpendicular to the direction of the wave. These waves do not require a medium to travel and can travel in a vacuum also.

Longitudinal waves - These waves are the waves where the particles of the medium travel parallel to the direction of the wave and these waves require a medium to travel and hence, cannot travel in a vacuum.

Thus, we can conclude that the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

Answer: The correct answer is the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

Explanation:

There are two main types of waves:

1. Transverse Waves: These waves are the waves where the particles in a medium travel perpendicular to the direction of the wave. These waves do not require a medium to travel and can travel in vacuum also. For Example: Light waves.

2. Longitudinal waves: These waves are the waves where the particles of the medium travel parallel to the direction of the wave and these waves require a medium to travel and hence, cannot travel in vacuum. For Example: Sound waves.

From the given options, the correct answer is the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

Ions are atoms of the same element that have a different number of _____________.Question 13 options:

C. electrons

D. protons

E. neutrons

Answers

The correct option is C.

How do an atom and an ion of the same element differ?

Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

What makes different ions of the same element different?

An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

The sound wave produced can best be described as a ?

Answers

the sound wave produced can be described As a longitudinal wave of constant frequency

Longitudinal waves are waves in which the displacement of the medium is in the same direction as or the opposite direction to , the direction of travel of the wave. In a constant frequency, our brain will acknowledge this wave as 'sound'
