Answer:
New Moon
Explanation:
Spring tides occur during new moons when the Sun and the moon are aligned, Pulling together creating big tides.
<span>Weight measured as a force in Newtonsis best described by the answer that is listed under option C. It is a measure of gravitational force on an object. So, interestingly an item with a specific mass of say 120KGs on earth would weigh 1200 N but on the moon only weigh 200 N due to the smaller gravitational force.</span>
Answer:
Option (a) is the correct answer.
Explanation:
The law of conservation of energy states that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.
Therefore, the total amount of energy before and after a chemical reaction is the same. Thus, energy is conserved.
Therefore, we can conclude that option (a) is the correct answer.
<h2>Mass preservation.</h2>
Explanation:
- Mass of the system must remain the same over time, as the system's mass cannot alter according to the law of preservation of mass for any closed system.
Landolt Experiment -
- Landolt was German chemist, He demonstrated the law of preservation of mass experimentally by utilizing H- glass tube filled with silver nitrate in appendage A and HCl corrosive in appendage B.
- The reactants were blended and a white accelerate of Silver chloride was shaped alongside nitric corrosive. The tube is weighed once more.
