Answer:
Explanation:
the development of the history of science, the histories of the individual scientific disciplines have played an enormously significant role. The goals and functions of these have recently received considerable attention, both because of the influence that such histories have had on the legitimacy and self-image of the disciplines and also because of the adaptability that they have shown when faced with the conceptual and methodological changes that they have undergone.
Phosphorus is a macro element that is a component of ATP
A magnet is made from materials that is magnetized and create its own persistent magnetic field while a electromagnet is mad from coil of wire which acts as a magnet when electric current passes through it.
Answer:
b friction
Explanation:
Contact forces
Contact forces are forces that act between two objects that are physically touching each other. Examples of contact forces include:
Reaction force
An object at rest on a surface experiences reaction force. For example, a book on a table.
A box rests on a table. There are two arrows, equal in size but going in opposite directions, up and down, from the point where the box meets the table.
Tension
An object that is being stretched experiences a tension force. For example, a cable holding a ceiling lamp.
A box hangs from a rope. Two arrows which are equal in size act upwards and dowards from the top and bottom of the rope.
Friction
Two objects sliding past each other experience friction forces. For example, a box sliding down a slope.
A box rests on an incline. There are three arrows; one acting vertically downwards from the centre of the box’s base. One arrow acts perpendicular to the incline. One arrow acts up the incline.
Air resistance
An object moving through the air experiences air resistance. For example, a skydiver falling through the air.
A box falls from the sky. Two arrows, equal in size and opposite in direction act upwards from the box and downwards from the box
When a contact force acts between two objects, both objects experience the same size force, but in opposite directions. This is Newton's Third Law of Motion.
<span>It is false that it is the obligation of researchers to review and comment on the research of other researchers. It is not their obligations - they don't have to do it, although they can if they want to and if they are allowed by the author him or herself. However, they are not bound by law or something like that to do this, it's just due to their kindness or genuine interest that they do this.</span>
