For this case we have by definition, that the Ampere, is the unit of electric current intensity.

For its part, the electric current is a measure of the velocity at which the electric charge flows.

The symbol of the current is A. We have that 1 Ampere is equivalent to an electric charge of a coulomb per second.

$1A = \frac {1C} {s}$

Answer:

$1A = \frac {1C} {s}$

Estimate the change in the equilibrium melting point of copper caused by a change in pressure of 10 kbar. The molar volume of co

mr Goodwill [35]

Answer:

The change in the equilibrium melting point is 4.162 K.

Explanation:

Given that,

Pressure = 10 kbar

Molar volume of copper $V=8.0\times10^{-6}\ m^3$

Volume of liquid $V=7.6\times10^{-6}\ m^3$

Latent heat of fusion $L= 13.05 kJ$

Melting point =1085°C

We need to calculate the change temperature

Using Clapeyron equation

$\dfrac{\Delta P}{\Delta T}=\dfrac{\Delta H}{T\Delta V}$

Put the value into the formula

$\dfrac{1000\times10^{5}}{\Delta T}=\dfrac{13050}{(1085+273)\times(8.0-7.6)\times10^{-6}}$

$\Delta T=\dfrac{1000\times10^{-5}\times(1085+273)\times(8.0-7.6)\times10^{-6}}{13050}$

$\Delta T=4.162\ K$

Hence, The change in the equilibrium melting point is 4.162 K.

Hey there!

The answer is that The data was not reliable because there was not any repetition.

An experiment should be completed multiple times to be sure of accurate results.

How are longitudinal and transverse waves alike? How are they different?

larisa86 [58]

Answer:

Longitudinal and transverse waves have many similarities and differences.

Explanation:

Similarities:

Mechanical waves can be transverse and longitudinal waves.

Transverse and longitudinal waves both have wavelengths and frequencies.

They both have amplitudes

Both waves can travel through a medium or not, but it depends on whether is an electromagnetic or a mechanical wave.

Differences:

Electromagnetic waves can only be transverse.

The particles of the medium in a longitudinal wave move parallel to the direction (motion) of a wave. It is in this back and forth motion.

The particles of the medium in a transverse wave move perpendicular to the direction (motion) of a wave. This means that there would be right angles showing that they are perpendicular.

Longitudinal waves have rarefactions and compressions.

These rarefactions and compressions are used to measure the wavelength of a wave. For instance, a wavelength in a longitudinal wave is measured from rarefaction to rarefaction

Transverse waves have troughs and crests.

Amplitude in a transverse wave is measured from the midline to the crest of trough.

Amplitude in a longitudinal wave is measured based on how closely packed the particles of the medium are

I hope this helps
