All the mass we ever encounter is positive - nothing weighs less than zero. What makes us think charge is different that there are both positive AND negative charges?

Respuesta :

As we know, there are two types of charges present.

1. Positive charge

2. Negative charge

  • In a positive charge particle, the  number of proton is greater than the number of electron. Thus, positive charge consists of more number of protons than electrons.
  • In a negative charge particle, the number of electron is greater than the number of proton. Thus, negative charge consists of more number of electrons than protons.

A positive energy balance, in which energy intake exceeds expenditure causes weight gain, with 60–80 % of the resulting weight gain being attributable to body fat.

In negative energy balance, when energy expenditure exceeds intake, the resulting loss in body mass is also accounted for by 60–80 % body fat.
