Explanation:
The pull strength is the highest possible holding power of a magnet, measured in kilograms. It is the force required to prise a magnet away from a flat steel surface when the magnet and metal have full and direct surface-to-surface contact.
Answer: There is no change in temperature when heat is given out or taken in by the object
Explanation:
The heat capacity of an object is infinite when it undergoing phase transition since the heat is ued in changing the state of the substance and ntot in raising the teperature of the substiance. Thus, heat capacity is infinite during change of state. This is known as latent heat. The correct option is
There is no change in temperature when heat is given out or taken in by the object
Answer:
Explanation:
For a drop in equilibrium, the weight is equal to the electric force (in magnitude):
where here we have
is the weight of the drop
is the magnitude of the electric force, which can be rewritten as
where
q is the charge of the oil drop
is the magnitude of the electric field
Substituting into the equation and solving for q, we find the charge of the oil drop:
