Remember velocity = distance/time so that mean you would do 60/3 which equals 20 so the speed(velocity) equals 20
<span>When a
substance is heated, its atoms gain
energy and begin to vibrate rapidly within the lattice
of the substance (the substance expands). As more heating continues, the atoms
gain even more energy and move more rapidly until they are able to overcome the
force of the bonds, that hold the atoms together
in the lattice, until the structure is disrupted. </span>
Answer:
Refer to the period table. Use the atomic mass for calculation. Multiply the atomic mass with the number of atoms. For example, Al2(SO4)3. (27 × 2) + (32 x 3) + (16 x 12) = molecular mass
Answer: Convection Currents
Explanation: The mantle rock is solid and denser because it is cooler. This means it will sink closer to lower mantle as warmer, lense dense rock/magma moves upwards.
NaHCO3 is the required substance often used in antacid and is used in Soda Acid Fire Extinguisher.
