Compounds are formed through chemical reactions. This process involves the making of interatomic bonds between one or more substances in order to form new substances. The type of change that must occur to form a compound is a chemical change. It refers to the process in which one or more substances (reactants) are changed into new products.
This usually involves the breaking or ...

It will be very difficult to say physics is more important than biology, vice versa. Both are important branches of science and have contributed immensely to the growth of science as a whole. Physics is a branch of science that deals with the study of the properties and interaction of time, energy, space, and matter.
This branch of science allows us to have a better understanding of ...

A person sitting in a moving car will have a form of energy known as potential energy. The reason is that the body is at rest, even though the car is moving. Potential energy is a form of energy possessed by an object at rest.
When you sit in a car, you are not using the energy stored in you to make the car move, but rather you are moving with the speed of the car. On the other hand, ...

The reason is that the man is trying to resist the sudden change in his velocity. In other words, the man is only trying to resist the change in his motion so that it can maintain the inertia of motion. This happens most of the time when the driver of a car suddenly applies brakes, probably because he wants to stop an accident from happening.
When a vehicle moves with a particular ...

I don't think there can be any real form of evacuation for humans if an event like this occurs. While humans have really advanced in terms of technology, I don't think we have what it takes to prevent an extinction-level event from occurring.
As far as I know, the highest we can only do is to predict the possible time of such an event and probably identify the possible direction of ...

According to the Aufbau principle, the filling of electrons into the orbitals of atoms is done in increasing order of energy levels. This means orbitals with lower energy levels will be filled first followed by orbitals with higher energy levels. While you might think the 4s orbital would have more energy than the 3d orbital, the reverse is actually the case.
The reason for this can ...

In order to have a complete living organism, the various parts of its body are arranged sequentially, from smaller to bigger body parts. The sequence of the levels of arrangement in organisms is this: cell, tissue, organ, system, and organism. The basic unit of life in all organisms is known as the cell.
The various chemical and biological activities in living organisms usually occur ...

We all know that gravity makes it possible for us to walk on land here on earth but it seems that there are still differences with how people view gravity. For example, the definition of gravity given by Einstein is different from that of Newton’s. Newton believed that gravity is a force but Einstein thinks differently. He thinks that gravity is “a type of distortion in the shape ...
