Answer:
- <em>Option D. temperature</em>
Explanation:
Indeed it is generally established that <em>temperature is a measure of the kinetic energy ot the particles</em>.
The <em>kinetic energy</em> of a particle is proportional to the product of the mass and the square of the speed. Mathematically, the kinetic energy, KE, is:
Where m is the mass and v the speed of the particle.
In a sample of matter, not all the particles have the same speed, hence not all the particles have the same kinetic energy.
The kinetic energy and the temperature are related by the Boltzman equation:
Where K is a constant (Boltzman constant) and T is the absolute temperature.
Therefore, as you can see from the last equation, <em>the temperaure is a measure of the averate kinetic energy of the particles in a sample of matter</em>.
This is, at a certain temperature, every substance has the same average kinetic energy.
The solution to the polynomial expression since the power of the variable is in the second degree is 6.29 × 10² cm
<h3>What is the power of a variable?</h3>
The power of a variable refers to the exponent of the variable and the highest power of a variable is the degree to which the variable is being raised. From the information given, the highest power of the variable is a polynomial.
Given that:
So, since the exponents are in the same power we are going to add them all together multiplied by their exponent.

Answer:
79.904 grams.
Explanation:
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Bromine, or 79.904 grams.
It means is where something is removed or erased completely or something unwanted or unpleasant.
Hope this helps and the right meaning of expunge.
