During the digestion process, the first step would be mastication, lubrication with the saliva, and later on is being formed into a bolus. Bolus is the term used for food substance that is turned into small balls. When the bolus is formed, this is then pushed or moved to the stomach.
Answer:
1 079 280 000 km / hr
Explanation:
2.99800 x (10^8) (m / s) =
So use equation: ΔH = MCΔT
M = mass of water
C = waters specific heat capacity (4.18)
ΔT = the temp. change of the reaction
ΔH = 100 x 4.18 x 10 = 4180J or 41.8KJ
so the cube absorbed 4180J of energy
hope that helps
Answer:
A. True
B. True
C. False
D. False
Explanation:
Electrons travel around the nucleus in circular orbits and moves from one orbit to another orbit when they absorb energy or lose energy. The Bohr atom is the model currently accepted for electrons in atoms because this model provides the right information about presence of electrons around the orbits. Scientists know the energies of electrons as well as the areas (orbitals) where the electrons are probably located with the help of new technology.
