Answer:
The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.
The seasons are caused as the earth, tilted on its axis, travels in a loop around the sun each year
Answer:
Both molarity and molality involves number of moles of solute
Explanation:
Molarity is obtained by dividing the number of moles of solute by the volume of solution in liters. Note that a solution is formed when a solute is dissolved in a given volume of solvent.
Molality, of a solution is obtained by dividing the number of moles of a solute by the number of kilogrammes of solvent.
In both cases, the number of moles of solute is involved. Hence, the number of moles of solute present is common to both molarity and molality calculation.
Answer:
Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
