The table shows the same data about how the temperature of each bottle of soda changed over 25 minutes.
Bottle Initial temperature (°C) Final temperature (°C)
Brown bottle 18
26
Clear bottle 18
22
Which statement is correct?
Thermal energy was transferred more slowly into the brown bottle.
Thermal energy was transferred more slowly into the clear bottle.
Thermal energy was transferred into both bottles at the same rate.

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
