Answer:

Explanation:

The formula for kinetic energy to be used here is 1/2mv².

If the first particle is "particle a" and the second particle is "particle n"; there kinetic energies (K.E) will be

K.Eₐ = 1/2.m2v² = mv²

K.Eₙ = 1/2.2mv² = mv²

From the above, <u>it can be said that there kinetic energies are the same</u>.

NOTE that the m and v used in the question means mass and velocity respectively.

What might be happening since 1880 for average global temperatures to increase
bazaltina [42]

Answer:

The average global temperatures has increased since 1880 due to the emission of toxic gases in the atmosphere.

Explanation:

  • In average the global temperature of the earth has increased by 1 degree Celsius (2 degrees Fahrenheit). It includes the combined land and ocean's temperature.
  • The main reason for this increase in global temperature is the emission of gases like carbon dioxide, CFC's and other greenhouse gases.
  • Human activities, industrialization, modernization etc. are majorly responsible for this increment in temperature through the centuries.
