Explanation:
In brief, electrons are negative charges and protons are positive charges. An electron is considered the smallest quantity of negative charge and a proton the smallest quantity of positive charge.
Two negative charges repel. Also, two positive charges repel. A positive charge and a negative charge attract each other (all experimentally verified.)
Point Charge: An accumulation of electric charges at a point (a tiny volume in space) is called a point charge.
Note: When an atom loses an electron, the separated electron forms a negative charge, but the remaining that contains one less electron or consequently one more proton becomes a positive charge. A positive charge is not necessarily a single proton. In most cases, a positive charge is an atom that has lost one or more electron(s).
Answer:
the answer is 558 km/h in kilometers per hour
Answer:
The volume of the balloon would be (580.12m) cm^3
Explanation:
From the ideal gas equation,
PV = nRT
P is pressure in the balloon = 742 mmHg = 742/760 = 0.976 atm
V is the volume of the balloon
n is the number of moles of carbon dioxide in the balloon. Let the mass of carbon dioxide be m.
n = mass/MW = m/44 = (0.023m) mol
R is gas constant = 82.057 cm^3.atm/mol.K
T is temperature of the balloon = 27 °C = 27 + 273 = 300 K
V = 0.023m × 82.057 × 300/0.976 = (580.12m) cm^3
Explanation:
For a charge concentrated nearly at a point, the electric field is directly proportional to the amount of charge; it is inversely proportional to the square of the distance radially away from the centre of the source charge and depends also upon the nature of the medium.
