What is magnet and types? Permanent magnets are magnets that retain their magnetism once magnetized. Temporary magnets are materials magnets that perform like permanent magnets when in the presence of a magnetic field, but lose magnetism when not in a magnetic field. Below we breakdown the various types of magnet available. What are the main […]
How do you determine incidence?
How do you determine incidence? Therefore, the term ‘person-year’ was used, which was defined as the number of quarters of the year that a patient was registered in a general practice.

Can you solve physics problems?
Can you solve physics problems? Multiply and divide the quantities until the units match the units of the answer quantity. For example, if you’re trying to find Potential Energy (kg*m2/s2) and you have the height (m), mass (kg) and gravitational acceleration (m/s2), you can match the units by multiplying the three quantities (m*kg*m/s2=kg*m2/s2). How do […]

Does changing current affect voltage?
Does changing current affect voltage? To answer this question, the relationship between the voltage and current variables given must be specified. and thus that the current will change proportionally with the voltage. and thus the current will change exponentially with the voltage. Does higher voltage draw less current? If the voltage out is twice that […]
