Answer:
Second Option: it suddenly drops to zero
Explanation:
Superconductors are resistance free materials that enable (allow) <u>electricity conduction (i.e. electron transportation between atoms)</u>.
As the superconductor temperature is gradually lowered, eventually a Critical Temperature is reached, where the <u>superconductor electrical resistivity</u> suddenly drops to zero. Such drop is so fast, that can be described as a complete matter-phase transition. This is in contrast with typical conductors,<em> where with gradually decreasing temperature there is also a gradually decreasing resistivity (which is also true at temperatures of near absolute zero). </em>
Thus the correct answer is the Second Option: it suddenly drops to zero

The highest entropy for the jar of marbles is represented by the marbles are arranged in a random order.
<h3>
What is entropy?</h3>
Entropy is the measure of the degree of disorderliness of a system or degree of randomness of a system.
Entropy of a system increases with increase in randomness of the system or disorderliness of the system.
Thus, the highest entropy for the jar of marbles is represented by the marbles are arranged in a random order.

Explanation:
Let n be the number of the vernier scale division which coincides with the main scale division. Rotate the vernier caliper 90° and repeat the steps 4 and 5 for measuring the internal diameter in perpendicular direction. To measure the depth, find the total reading and zero correction.

Answer:
7. 01 * 10^7 N/C
Explanation:
Parameters given:
Distance, y = 2.9 m
Radius, R = 2.9 cm = 0.029m
Charge, Q = 5.0 µC = 5 * 10^(-6) C
Given that:
E = 2πKσ(1- [y/(R² + y²)]) j^
Charge density, σ, is given as:
σ = Q/A = Q/πR²
=> E = 2πKQ/πR² (1- [y/(R² + y²)]) j^
E = 2KQ/R² (1 - [y/(R² + y²)]) j^
E = (2 * 9 * 10^9 * 5 * 10^(-6) / 0.029²) (1 - [2.9/(0.029² + 2.9²)]) j^
E = 107015.46 * 10^3 *(1 - 2.9/8.41) j^
E = 107015.46 * 10^3 * 0.655 j^
E = 7.01 * 10^7 j^ N/C
The magnitude of the electric field is 7.01 * 10^7 N/C. The j^ shows the direction.
