What is the relationship between dipole moment and boiling point?
Lelu [443]
The dipole moment of a molecule and its boiling point are directly varied. If the dipole moment is large, the attraction between the positive and negative charges of a molecule is strong thus, requiring stronger forces to break them. Hence, they will have higher boiling points.

A current of 17.0 mA is maintained in a single circular loop of 2.00 \mathrm{~m} circumference. A magnetic field of 0.800T is di
poizon [28]

The magnetic moment is -

M = 5.5 x 10^{-3} Am^{2}.

We have current carrying single circular loop placed in a magnetic field

parallel to the plane of the loop.

We have to determine the Magnetic moment of the loop.

<h3>What is the formula to calculate the magnetic moment of loop?</h3>

The formula to calculate the magnetic moment of the loop is -

M = NIA

where -

N -  Number of turns

I - Current in the loop

A - Area of the loop

According to the question, we have -

I = 17mA = 0.017A

Circumference (C) = 2 meters

B = 0.8 T

Now -

C = 2

2\pir = 2

\pir = 1

r = \frac{1}{\pi }

r = 0.32

Using the formula -

M = NIA

M = \piNIr^{2}

M = 3.14 x 1 x 0.017 x 0.32 x 0.32

M = 3.14 x 4 x 0.017

M = 5.5 x 10^{-3} Am^{2}

Hence, the magnetic moment is -

M = 5.5 x 10^{-3} Am^{2}

Define the term antinode and explain how standing waves form.
Otrada [13]

Answer:

standing wave, also called stationary wave, combination of two waves moving in opposite directions, each having the same amplitude and frequency.

For oppositely moving waves, interference produces an oscillating wave fixed in space. fixed nodes in a standing wave. Location of fixed nodes in a standing wave

these are the points that undergo the maximum displacement during each vibrational cycle of the standing wave. In a sense, these points are the opposite of nodes, and so they are called antinodes. A standing wave pattern always consists of an alternating pattern of nodes and antinodes

soldier1979 [14.2K]

Answer:

B. Time and Space

Explanation:

Matter is a pshyical or corporeal susbtance in general, whether solid, liquid, or gaseous especially as distinguised from incorpeal substance, as spirit or mind, or form qualities, actions, and the

Within this time-and-space boundary, all matter exists. All matter is made up of atoms. Because these atoms take up space in the universe, solids, liquids, and gases are recognized as existing and may be found in all three dimensions.

Time is a figurative term. Space has three dimensions but time only has one.
