Answer:
This is Newtons 2nd Law: Force is directly proportional to the acceleration of the object, acceleration is inversely proportional to the mass of the object.
Answer:
Explanation:
Sugar and Salt even thought they both dissolve in water they both dissolve in different ways. When salt dissolves in water, its individual types of ions are torn apart from each other, while Sugar molecules stay together when dissolved in water, and therefore the molecules remain the same when dissolved in water. This being said in science using your senses can be just as valuable as using calculations. In this case both Sugar and Salt taste differently. Sugar is sweet while Salt is salty. Therefore tasting the substance can be the easiest and most accurate way of determining the substance.

The pressure of a sample of a gas if the temperature is changed to 127 c while the volume remains constant is calculated using gay lussac law formula
that is P1/T1 = P2/V2
P1 = 100 torr
T1 = 27+273 = 300 k
T2 =127 +273 =400 k
P2=?
by making P2 the subject of the formula
P2=T2P1/T1
=100 x 400/300 = 133.3 torr
Sound is a form of energy is incorrect
Sound is caused by the movement or vibration of matter
Atomic number of F = 9
Electron configuration of F:-
⁹F = 1s² 2s² 2p⁵
Incase of F2: Total electrons: 9 + 9 = 18
For F2 the ground state electron configuration would be:
F2 = (1σ)²(1σ*)²(2σ)²(2σ*)²(2pσ)²(2pπ)⁴(2pπ*)⁴
Incase of F2+: There is loss of one electron from neutral F2. Total electrons: 18-1 = 17
For F2+ the ground state electron configuration would be:
F2 = (1σ)²(1σ*)²(2σ)²(2σ*)²(2pσ)²(2pπ)⁴(2pπ*)³
