It is true, because a strong magnet that can be turned off and on is an electromagnet.
Answer:
Electron gain enthalpy becomes more and more negative from left to right in a period. As we move across a period from left to right the atomic size decreases and the nuclear charge increases
Answer: Major scale and minor scale both relate the precision of measurements with more true value of measurement.
Explanation:
Major scale in a measuring device is maximum unit value on the scale that can be measured.
Minor scale in a measuring device is a least unit value on the scale that can be measured.
In a metric ruler major scale is 1 cm and minor scale is 0.1 mm which means one can measure accurate value up-to one decimal point and in 10 ml of graduated cylinder major scale division is 1 ml minor scale division is 0.01.
