How fast is sound when traveling through water?

1 answer:

4 0

Sound travels 1,480 meters per second, which is about 4.3 times as fast as air. Sound travels much slowly in air. This has to do with the frequency, intensity and amplitude of waves, which are affected differently in water and air.

Higher Current = ________ Moving Electric Charges (Electrons) *

Eva8 [605]

Answer:

Higher current is normally achieved by faster moving electrons.

Explanation:

Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.

Current is the net charge flowing per unit time.

Current can be represented by:

I=v×e×N×A

where,

I= current

e= electric charge

v= speed of electrons

N=no. of free electric charges per volume

The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.

It probably also has a nineth of the speed, so it's 81 earth years. If they had the same speed, it would be 9 earth years. Probably the first one is more accurate :-??

Vesnalui [34]

Answer:

A) Having a positive slope

D) Approaching zero pressure as temperature approaches infinity

Explanation:

A fixed amount of ideal gas is kept in a container of fixed volume. The absolute pressure P, in pascals, of the gas is plotted as a function of its temperature T, in degrees Celsius. Which of the following are properties of a best fit curve to the data? Select two answers.

A) Having a positive slope

B) Passing through the origin

C) Having zero pressure at a certain negative temperature

D) Approaching zero pressure as temperature approaches infinity

solution

from the ideal gas equation

PV=nRT

P=pressure

T=absolute temperature in kelvin

V=volume

R=gas constant 8.314j/molK

n=mole= mass/molecular mass

P=nRT/V

nR/V is the constant

P=nR(Tc+273)/V

plotting the graph we will discover that as pressure increases , temperature also increases . which means it's a positive graph.

Also Approaching zero pressure as temperature approaches infinity
