19685 because 1 km in inches is 39370 approximately so you just have to cut it in half
I think that it is A) Conduction
Answer:
The plum-pudding model proposed that an atom is composed of negatively-charged particles floating within a sea of positive charges. This sea of positive charges served to counterbalance the negative charge on the electrons so that the atom remains neutral.
Explanation:
J.J. Thompson from experiments he conducted with the rays produced from a cathode tube to which a high voltage is applied across its two ends, discovered that these rays were negatively charged and had a mass much much smaller than the mass of any known atom. These negatively-charged rays were later called electrons. Since the atom was neutral in charge overall, J.J. Thompson then proposed the plum-pudding model.
The plum-pudding model proposed that an atom is composed of negatively-charged particles floating within a sea of positive charges. This sea of positive charges served to counterbalance the negative charge on the electrons so that the atom remains neutral. The name of this model was chosen because it resembled the English dessert, plum-pudding.
Answer:
mass of the butter is 2.107 kg
Explanation:
specific gravity = destiny of the substance / density of
the water at 4°C
0.86 = density of the butter / 1000
where density of the water is 1000 kg/m^3 at 4°C
density of the butter = 860kg/m^3
now,
density of the butter = mass of the butter / volume
860 = mass of the butter / 2.45 × 10^-3
( 1 L = 10^ -3 m^3)
mass of the butter = 2.107 kg
can I get brainlist plz
As temperature increases, the particles will gain kinetic energy causing it to move more rapidly and randomly. However, this causes the gas to expand as the particles will have more energy to roam freely. Hence as temperature increases, Volume increases.
This is based on Charles' Law stating that the volume of a gas is directly proportional to its absolute temperature.
