Neutral Magnesium atom
Explanation:
From the given description of the atom, one can infer that this atom is a neutral atom.
In a neutral atom, the number of protons and neutrons are the same.
Atomic number = 12
Mass number = 25
This atom is Magnesium.
Magnesium has an atomic number of 12 from the periodic table.
Number of protons = 12 = atomic number
Number of electrons = 12(for neutral atoms, atomic number is same as number of electrons).
Number of neutrons = mass number - atomic number = 25-12 = 13.

Answer:
Distance 5 km, Displacement 3 km east
Explanation:
MA = (Effort Distance)/(Effort Resistance) = L/H
L = MA * H = 5 * 8" = 40"
Answer:
M = 6.32 x 10⁻⁶ H
Explanation:
given,
Length of solenoid = 10 cm = 0.1 m
diameter = 0.40 cm
radius = 0.2 cm = 0.002
number of turns, N₁ = 800
N₂ = 50
mutual inductance will be equal to
M = 6.32 x 10⁻⁶ H
hence, mutual inductance of the combination of two coil is equal to M = 6.32 x 10⁻⁶ H
Pressure and temperature are the variables in Gay-Lussac's law.
The law states that a pressure of a gas is directly proportional to the gas' temperature if the mass and volume are fixed. This means that there are only two variables, as the other two values are fixed: only pressure and temperature can change according to this law.
