Science Quiz-energy: Heat Transfer, Electricity, Wave Energy

Explanation
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.

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."

Explanation
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.

Explanation
A wave is defined as energy moving from one point to another. This energy can be transferred through various mediums such as water, air, or even electromagnetic fields. In the context of ocean waves, the energy is carried by the movement of water particles, causing them to oscillate up and down or back and forth. This energy propagates through the water, eventually reaching the shore where it crashes or breaks. Waves can also occur in other forms, such as sound waves or light waves, where the energy is transmitted through air or electromagnetic fields respectively.
