Answer :
1) Luster → the shininess of a material
2) Freezing point → temperature at which a liquid becomes a solid
3) Viscosity → the measure of a substance's resistance to flow
4) Solubility → ability to dissolve in another substance
5) Ductility → able to be pulled into a wire
Explanation :
Luster : It is defined as the material which has the shining property.
Freezing point : It is the temperature at which the phase changes from liquid state to solid state at low temperature.
Viscosity : It measures the resistance of the liquids to flow .
Solubility : It is defined as the ability of a substance (solute) to dissolve into a liquid (solvent).
Ductility : It is defined as the ability of a metal into a thin wire without breaking.
The type of cell that does NOT use cell division to replicate is the reproductive.
If I'm wrong then, well.. at least i tried.
Answer: τ = 0
Explanation:
At constant angular velocity there is no angular acceleration therefore no torque.
τ = Iα
m = mass of the cat being lifted = 5 kg
h = height to which the cat is raised into air = 2 m
g = acceleration due to gravity of earth = 9.8 m/s²
U = gravitational potential energy gained by the cat
Gravitational potential energy gained by the cat is given as
U = m g h
inserting the values in the above equation
U = (5 kg) (9.8 m/s²) (2 m)
U = (5 x 9.8 x 2) (kg m²/s²)
U = 98 J
Answer:
E; The object is negatively charged
Explanation:
Here, we want to state the conclusion that can be drawn from a positively charged rod being attracted to an object.
Generally as we know, oppositely charged materials attract while the ones with same charges repel each other.
Thus, in this case, for the rod to attract the object, there must have been an opposite charge of negativity on the object
So we conclude that the reason why the rod attracted the object was because of the presence of opposing charges on both of them. And since the rod has taken the positive charge, it is only correct to state that the object is negatively charged
