First, it is necessary to calculate the energy consumed by the bulb during the weekend:
(It is important to express time in seconds).
The energy associated with water is gravitational potential energy and we can write this type of energy depending on volume of water:
Clearing volume in the previous equation:
Answer:
B. ceramics
Explanation:
Ceramics are materials which are inorganic and non-metallic materials made from compounds of metals and non metals. They are usually oxides, carbides and nitrides. They are stronger, harder and more resistant to heat than a wide variety of other types of materials. They found a great use in the industry such as for making glass wares, pottery , valves, spark plugs, pressure sensors, vibration sensors,bricks, cement,insulators, resistors, superconductors, capacitors ,ceramic rotors e.t.c.
Static electricity is the BUILT UP STORE of electron charges [e-] between a pair of objects, while current electricity is the FLOW of electrons between these objects.
Static electricity is a transfer of charge from one static body to another, resulting in an imbalance in positive and negative charges, while electric current is the flow of electrons, from one static body to another.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.
The answer is “B” hope I helped
