Answer:
54 Joules
Explanation:
recall that kinetic energy is governed by the equation:
K.E = (1/2) mv²
where,
m = mass = given as 3 kg
v = velocity = given as 6 m/s
Substituting these known values into the above equation,
K.E = (1/2) mv²
K.E = (1/2) (3)(6)²
K.E = 54 Joules
Sulphur (S), Iodine (I) and Magnesium (Mg) are all three, solids at the room temperature. Thus they have the same phase at room temperature.
Sulphur and Iodine are not good conductors of electricity.
Also while Sulphur is in group 6, Magnesium is in group 2. Therefore they do not have the same number of valence electrons. Sulphur is making anions (negative ions) and Magnesium is making cations (positive ions).
True
Variables is changing. It is any factor, trait or condition that can exist in differing amounts or types. An experiment has three types: Independent, Dependent and Controlled.
