Answer:

There is solid proof that global warming is increasing and getting worse by t he day. The ice caps slowly melt more and more each year due to this which is a proven fact. On top of that, it has been proven that carbon emission by humans is bad for the environment and it helps increase the problem of global warming by weakening our atmosphere. As for the cold days, just because we have global warming doesn't mean the earth weather wont be cold. global warming is something that slowly happens and over time the temperature global has actually been increasing at a not very notice able pace.

Explanation:

Yes, climate is changing because of the human activities which are causing harm to the environment causing global warming.

Global warming is the long-term warming of Earth's climate system that has been seen from the pre-industrial period (between 1850 and 1900) as a result of human activity, principally fossil fuel combustion, which raises heat-trapping greenhouse gas levels in the atmosphere.

Explanation:

The observations are as follows:  Initially with the plates in the dark, no electrons pass between the plates and no current flows.   As we shine light on the plates, going from low energy red to high energy blue, suddenly current begins to flow.  How?

Einstein explained the result be describing the light waves as packets of energy.  He called the packets of energy photons.  Each photon has a specific energy, the shorter the wavelength, the higher the energy.  When a high-energy photon hits the plate (such as a green or blue), the photon has enough energy to knock out an electron and then the electron, being negative, will fly to the positive side.  At this point, current flows.

The lower energy photons are unable to know out the electrons and no energy can flow.

The exciting thing to note is the treatment of energy as a particle or a packet, it is consistent with the fact energies are not additive.  If we can bump electrons with light at 600 tera-hertz , we can�t just use 300 tera-hertz for twice the time and still expect to bump electrons.

What if the photon has greater than the threshold energy required to pop out an electron?  The extra energy just goes into the kinetic energy of the electron.  This relationship can be described by the following equation.

hf = w + KE

where hf is the energy of the photon.

w is the energy required to bump an electron.

KE is the kinetic energy of the electron.

If the photon has less energy than w, no electron is emitted.

Answer:

a compound of the elements hydrogen, carbon, and oxygen. (also carbonic acid is a compound not a mixture ^-^)

Explanation:

hope this helps dude

According to the concept of solubility, carbonic acid is a mixture of water and carbon dioxide.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

A mixture of water and carbon dioxide under high temperature and pressure forms carbonic acid as it is highly soluble,thus carbonic acid is a mixture of water and carbon dioxide.

Answer:

Like magnetic poles repel each other

Explanation:

Among the following statements, the one that is true is Like magnetic poles repel each other.

Magnets are substances which possess their own magnetic field this magnetic field basically arises from the circular movement of negatively charge electrons. The elements which have unpaired electrons and have spin angular momentum or orbital angular momentum or they are together present are called as Magnets.

The magnetic field present is invisible but it is definitely responsible for the most notable property of a magnet. Magnetic force is a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

Therefore, Among the following statements, the one that is true is Like magnetic poles repel each other.
