Answer:
"Option B It acts on all objects all of the time.
Explanation:
"Gravitational force" is a kind of force that will attract any object with a mass. It is a "natural phenomenon" where all the things, including in planets in-universe, of mass or energy, are brought towards each other.
Like the earth’s gravity helps in giving weight to objects and the ocean tides are caused because of the moon’s gravity. The example of gravity force is the force with which sun holds together the gases in it.
Answer: The abundance of Li-7 isotope is higher as compared to Li-6.
Explanation:
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
We are given:
Two isotopes of lithium :
Li-6 and Li-7
Average atomic mass of lithium= 6.941
As, the average atomic mass of lithium is closer to the mass of isotope Li-7. This means that the relative abundance of Li-7 is higher as compared to Li-6.
Percentage abundance of Li-7> Percentage abundance of Li-6 isotope
Answer: 72
Explanation: there is 48 teaspoons in a cup, take 48 then divide that by 2 u get 24 then u add 24 to 48 then u get 72
