The mass of solid lead would displace exactly 234.6 liters of water should be <span>2,674,440</span>
NO, two atom with the same mass number can never be isotope of each other.
This is because for atoms to be considered as isotopes, they must have the same number of protons but different number of neutrons. There is no way two atoms will have the same mass number and their proton number will be the same, this means that two atoms with the same number of mass number can not be isotope of each other.
Answer:
The answer is B. It contains more non-penetrating solute particles than the interior of the cell.
Explanation:
This means that it has a greater concentration or number of solute particles outside a membrane than there are inside it.
A typical example is Saline solution.
Answer:
its height relative to some reference point, its mass, and the strength of the gravitational field
Explanation:
Gravitational energy is the potential energy associated with gravitational force, such as elevating objects against the Earth’s gravity. The potential energy due to elevated positions is called gravitational potential energy.
The factors that affect an object’s gravitational potential energy are the following; its height relative to some reference point, its mass, and the strength of the gravitational field it is in. For instance, consider a wallet lying on a table, it has less gravitational potential energy than the same wallet lying on top of a taller cupboard, and yet lesser gravitational potential energy than a heavier wallet lying on the same table.
If an object lies at a certain height above the Moon’s surface, it has less gravitational potential energy than the same object lying at the same height above the Earth’s surface because the Moon’s gravitational force is weaker.
