Answer:
In a circuit ,<u> VOLTAGE </u>can be said to be the "source" or the "push of electrons". This push then creates what is known as a <u> CURRENT , </u>which is the flow of electric charge through the circuit. This flow can the slowed down or restricted by <u>RESISTOR </u>, and this is also what can be harnessed in order to use electric <u>ENERGY </u>.
Explanation:
Voltage:
It is the 'push' that causes charges to move in a wire or other electrical conductor, also it is a Source input to the electric circuit.
Measured in Volts.
Current:
An electric current is the rate of flow of electric charge from a point or through a region.
Measured in Ampere.
Resistor:
Resistor is used to resist the flow of charge or to resist the current called as Resistance.
Measured in Ohms.
Electric Energy:
Electrical energy is a form of energy resulting from the flow of electric charge.
Measured in Joules.

Answer:
The temperature coefficient of resistivity for a linear thermistor is 
Explanation:
Given that,
Initial temperature = 0.00°C
Resistance = 75.0 Ω
Final temperature = 525°C
Resistance = 275 Ω
We need to calculate the temperature coefficient of resistivity for a linear thermistor
Using formula for a linear thermistor



Put the value into the formula


Hence, The temperature coefficient of resistivity for a linear thermistor is 
Answer:
Distance is 500 m, displacement is 0
Explanation:
Distance and displacement are defined in two different ways:
- Distance is the total length of the path covered by an object in motion - so it depends on the path taken. In this problem, the distance travelled by the car corresponds to the length of one lap, which is the length of the track, so 500 m
- Displacement is the distance in a straight line between the final point and the initial point of the motion. This means that displacement does not depend on the path taken, but only on the starting and ending point of the motion. In this problem, the car completes one lap, so the final position of the car is equal to its starting position - therefore the displacement is zero, since the distance between these two points is zero.
