How is a scientific law formed? Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. Laws are developed from data and can be further developed through mathematics; in all cases they are directly or indirectly based on empirical evidence. What are […]

What happens when a charged particle enters a uniform magnetic field? The simplest case occurs when a charged particle moves perpendicular to a uniform B-field (Figure 11.4. 1). The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion. When a charged particle enters […]

What are the only reasons to move an injured person? In what situations is it appropriate to move an injured or ill… When you are faced with immediate danger, such as fire, lack of oxygen, risk of explosion or a collapsing structure. When you have to get to another person who may have a more […]

How we can make magnetic field? By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but […]

Why does MacCready make a model and take it to the swimming pool? [MacCready] went so far as to make a mini model of the Condor, which he flew around in a swimming pool in order to better understand the effects of air mass on the square wing with respect to making turns. What was […]
