Light coloured objects ____________ heat.
Explanation
Light colored objects absorb heat. When an object is light in color, it reflects most of the light that falls on it. However, it also absorbs a small amount of light, and this absorbed light is converted into heat energy. Dark colored objects, on the other hand, absorb more light and therefore more heat. So, the correct answer is "absorb."Rate this question:

What is the law of Conservation of energy?
-
Energy can be created but not destroyed
-
Enrgy can destroyed but not created
-
Energy cannot be created nor destroyed it can only change form
-
Energy can only be transformed in to Electrical energy
Correct Answer
A. Energy cannot be created nor destroyed it can only change formExplanation
The law of Conservation of energy states that energy cannot be created nor destroyed, it can only change form. This means that the total amount of energy in a closed system remains constant, although it can be converted from one form to another. This principle is based on the understanding that energy is a fundamental property of the universe and is always conserved.Rate this question:

V ----- This is Ohm's law i | r
-
True
-
False
Correct Answer
A. TrueExplanation
The given answer is true because the table represents Ohm's law, which states that the current (i) flowing through a conductor is directly proportional to the voltage (V) applied across it and inversely proportional to the resistance (r) of the conductor. Therefore, the statement "This is Ohm's law" is correct.Rate this question:
