Answer:
A battery is made up of three parts. The Cathode (positive end +) , the Anode (negative end -) and the electrolyte. The electrolyte allows electrical charges to travel between the cathode and anode. This chemical reactions creates the flow of electricity supplying the electrical voltage potential to power a circuit.
Typical materials of a battery are as follows
- Anode most often is made of zinc
- Manganese dioxide acting as Cathode.
- the electrolyte between and inside contains ions
Explanation:
Hello!
In a thermostat, the property of the bimetallic coil that allows it to contract and expand is that The two metals absorb different amounts of thermal energy.
This bimetallic coil is used to transform thermal energy into mechanical movement. Two metals with different thermal expansivity are joined together parallelly and the changes of temperature cause bending in different directions depending on if the temperature is rising or descending.
The differences in the thermal energy absorption of the two metals are the basis for the mechanism of this device.
Answer:potential energy=810000j
Kinetic energy=810000j
Mechanical energy=810000j
Explanation:
Mass(m)=5000kg
Velocity(v)=18m/s
Kinetic energy=(mxv^2) ➗ 2
Kinetic energy =(5000x18^2) ➗ 2
Kinetic energy =(5000x18x18) ➗ 2
Kinetic energy =1620000 ➗ 2
Kinetic energy =810000j
Kinetic energy = potential energy
Since energy can neither be created nor destroyed
