Answer is: c. impulse acting on the object.
Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.
The impulse-momentum change equation: F· t = m · Δ v.
The impulse experienced by the object equals the change in momentum of the object.
Sodium phosphide is the inorganic compound with the formula Na3P.
The answer is D I hope this helps
They have strong intermolecular forces between their atoms, hence why more heat is necessary.
Answer is D - Argon atom
Potassium has atomic number as 19. Hence, number of protons = 19
If the atom is neutral,
number of protons = number of electrons = 19
Hence, the electron configuration of potassium (K) is
1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹
Potassium ion is formed by losing an electron. Then the number of electrons = 19 - 1 = 18
Electron configuration of K⁺ is 1s² 2s² 2p⁶ 3s² 3p⁶.
This is same as the electron configuration of Ar which has 18 electrons.
