Answer:
Larynx
Explanation:
The larynx is a cartilaginous structure inferior to the laryngopharynx that connects the pharynx to the trachea.
It should be 40.08 grams...because the atomic mass is equivalent to 1 mole of atoms of an element in grams, and 6.023 × 10^23 atoms of calcium is the same as 1 mole of calcium.
Hope this helps!
Answer:
The internal energy of a system <u>is the sum of the potential and kinetic energies of the components</u>
Explanation:
Internal energy is defined as the sum of two types of energy: kinetic energy and potential energy.
Kinetic energy is defined as the sum of all the kinetic energies that each element has within a system with respect to its center of mass. It is caused by the movement of particles. Meanwhile, the potential energy is the energy that is associated with each of the interactions. Potential energy is associated with the constituents of matter, of the electrostatic energy of each atom that is inside the molecules.
If the potassium atoms could be lined up in a row, it would take to make a 1.00 ft row of potassium atoms is 5.45 × 10⁻⁸.
Potassium atom is represented by K with atomic number 19. It is a silvery white metal.
Given,
Radius = 280pm = 280 × 10⁻¹²m
Diameter = 2radius = 560× 10⁻¹²m = 560pm
We know that,
1 feet = 0.305m
So, number of potassium atoms that fits into the row,
1 feet = 0.305/560 × 10⁻¹²
1 feet = 5.45 × 10⁻⁸
Hence, it takes 5.45 × 10⁻⁸ atoms of potassium to make a 1 feet row.
