Answer:
Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).

In circuits, the average power is defined as the average of the instantaneous power over one period. The instantaneous power can be found as:
So the average power is:
But:
So:

In terms of RMS values:
Ionization energy, according to <span>chem.libretexts.org,</span><span> is the quantity of </span>energy<span> that an isolated, gaseous atom in the ground electronic state must absorb to discharge an electron, resulting in a cation. This </span>energy<span> is usually expressed in kJ/mol, or the amount of </span>energy<span> it takes for all the atoms in a mole to lose one electron each.</span>
Answer:
7.24 Ω
Explanation:
Power = energy / time = 195 J / 9.81 = 19.88 W
and power = V² / R
R resistance = 12 V² / 19.88 W = 7.24 Ω
The question seems to be what is an equilibrant force.
The answer is "an added force that produces equilibrium.
Here you have more insight:
<span>an object that has no net force acting on it? This object indeed is in equilibrium but the object is not the equilibran force.
the reaction force in an action-reaction pair of forces?
the reaction force is not an equilibrant force. The reaction force exists always but equilibrium is only possible if the net force is cero.
an added force that produces equilibrium? this is the right answer.</span>
