Answer:

D. Friction

Explanation:

Friction is a force that opposes motion. So a perpetual motion machine can never be built because it is impossible to eliminate frictional force. It can only be reduced

What elements are solid liquid and gas at room temperature?
Alona [7]

Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules.

Titanium, Lead, Potassium, and Silicon are solids at normal temperature.

Mercury and bromine (Br) are the only liquid elements at standard pressure and temperature (Hg).

<h3>What are chemical elements?</h3>

A chemical element is a species of atoms, including the pure substance made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.

Question on Resistance. WORTH 20 POINT
kirill [66]

From Ohm's law:  R = V / I

Resistance = (voltage) / (current)

The first paragraph TELLS you that the current is always 0.5 A, and the table tells you the voltage across each piece of wire.

Again . . .  <em>R = V / I</em>

Consider the following spectrum where two colorful lines (A and B) are positioned on a dark background. The violet end of the sp
Dmitry_Shevchenko [17]

Answer:

Explanation:

a )

This type of spectrum is called line emission spectrum . Because it consists of lines . It is emission spectrum because it is due to emission of radiation from a source .

b ) The wavelength of a photon  is inversely proportional to its energy .  Photon  due to transition between n = 1 and n = 3 will have higher energy than

that due to transition between n = 2 and n = 5 . So the later photon ( B)  will have greater wavelength or photon  due to transition between n = 2 and n = 5 will have greater wavelength .
