Compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have ________.
Nikitich [7]
  • The answer is shorter wavelength and equal speed.                        

That is, compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have shorter wavelength and equal speed.

This can be seen by the reaction given below:

 h\times \upsilon =\frac{c}{\lambda }

h= Planck's constant

c=speed of the light

 \upsilon=frquency

{\lambda }=wavelength

So, higher is the frequency, lesser is the volume while speed remains constant as c is speed of light.

Consider the words or phrases below and drop them in the bucket that you would most associate with the word or phrase in the the
Dimas [21]

Answer:

1) non equilibrium

mass movement

unsaturated solution

2)equilibrium phase change

Heat of vaporization

condensation

heat of fusion

normal boiling point

vapor pressure

3) equilibrium reaction

saturated solution

Ksp

solubility

Ka

Explanation:

Nonequilibrium processes are those processes that are irreversible. They often lead to an increase in entropy of the system.

In chemical systems, a state of equilibrium is said to have been attained when the rate of the forward process equals the rate of the reverse process. This is true for both chemical reaction and phase changes. A state of equilibrium connotes a constancy in physical properties of a system over a period of time.

Indicate the number of significant figures in the following measured numbers:
inysia [295]

Answer: a = 2 ; f = 5 ; b = 2 ; g = 2 ; c = 2 ; h = 2 ; d = 4 ; i = 5 ; e = 3 ; j = 7

Explanation: Some rules to follow while calculating sig figs is

1. If a number like 4500 is present, only two sig figs are counted, but none of the zeros are, but if 4500. has a decimal point present, then you should count all the numbers available.

2. If a number like .0005 is present, only count 5 as a sig fig, however if the number is .00050, count the 0 after the 5 in this example (this would then have two sig figs.

Can somebody help me please? it’s urgent
Anettt [7]

Answers:

See attached table

Explanation:

The isotope symbol will have the mass number and chemical symbol.  The atomic number will be equal to the number of protons because the atomic number is the number of protons in an atom.  The electrons will be equal to the protons because the atom is neutral.  The neutrons can be found by subtracting the number of protons from the mass number.  The mass number can be found by adding the protons and neutrons.  It is also in the name of the isotope.
