Answer:
The symbol of each element is, Ne, Na, Mg, and Al.
Explanation:
Below is the list of elements that has an atomic mass of less than 19.3 u.
The atomic mass of Neon is 20.1797 u and the atomic number is 10.
The atomic mass of Sodium is 22.989769 u and the atomic number is 11.
The atomic mass of Magnesium is 24.305 u and the atomic number is 12.
The atomic mass of Aluminium is 26.981539 u and the atomic number is 13.
Here, the symbol of each element is, Ne, Na, Mg, and Al.
Answer is: heat energy.
Braking is the process of controlling the velocity of an object (in this example bicycle) by inhibiting its motion.
Mechanical energy can be either kinetic or potential energy and has to do with the energy of position and motion of an object.
Kinetic energy is energy of the speed of an object and how much mass it has; basically how the object is moving.
Potential energy is type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band.
A mechanical brake applies a friction force to convert the kinetic energy of the bicycle into heat energy which then dissipates into the atmosphere.
Answer:
1.204 × 10²³
Explanation:
The number of atoms in a mole is always 6.022 × 10²³, known as Avogadro's number or Avogadro's constant.
To convert moles to atoms, multiply the molar amount by Avogadro's number.
(6.022 × 10²³) × 0.2
= 1.204 × 10²³
Answer:
Oceans, Fossil fuels, atmosphere
It doesn't have enough solute. So say someone likes sweet tea. If you were to add more sugar it would still dissolve no matter how much is in the glass. Sorry if this is confusing.
