The ball isn't moving, so the mechanical energy is zero.
Answer:
Scientific advancements can detect some harmful events before they occur and it allows the society to plan for them, thereby reducing the risk of damage that occurs.
Explanation:
Scientific advancements reduce the natural disasters level in a region by evaluating the physical and chemical characteristics of the land.
Also, it develops new medical terminology and concepts that reduce the spread of hazardous diseases in society.
Satellites are used to predict the weather report and by using this report proper precautions can be taken at the time of floods and storms.
Construction of dams and canals highly reduced the risk of water overflowing in the lands.
Answer: Scientists are able to detect and predict some hazardous events through scientific advancements. By detecting these events early, society can prepare for the events, thereby reducing the amount of damage to people and property caused by the hazardous event.
Explanation: This is the exact answer on edge2020
Toothium (T): This is a nonmetal with an average atomic mass number close to 19.
Floatium (Fl): This is a gas that the aliens often use to fill balloons and blimps. It contains two protons in its nucleus.
Breathium (Bt): This element is a nonmetal and has one less proton than an atom of Toothium and has an atomic mass close to 16 amu.
Lightium (Lg): This is a gas that does not react with other elements. It glows when it is heated in a lamp or vacuum tube. It contains one more proton in its nucleus than Toothium.
Rottoneggium (Re): This is a nonmetal with one less electron than Mustarium. It has a total of 16 electrons in its electron cloud.
I honestly don't understand
A – solute and B – solvent
A – solute and B – solution
A – solvent and B – solution
A is marking the solvent molecules which is marked in blue. And B is marking the whole solution.
Option C
A solution is defined as the homogeneous mixture of a solute in a solvent in a range of concentration where generally solvent is more in amount than in solution.
A solute is the component of the solution which is generally less in amount and is homogenously mixed with the solution. Here they are marked in blue. And the molecules that are representing the solvent are marked in orange colour. The solute and the solvent total makes the solution which is marked by B.
When a pure substance undergoes chemical change, the pure substance changes in chemical composition.
Chemical change is any change that involves the formation of new substances or products and it is not easily reversible.
A pure substance is any substance that has a definite chemical composition.
However, when a pure substance undergoes chemical change, the chemical composition of the substance is changed to form new products.
