Explanation:
Resistance = Resistivity * Length / Area
= 30 * (1/3) / (1/4)
= 40x.
Hence the resistance of the constant wire is 2 * 40 = 80 ohms.

Answer:
<h3>Speed is the change in distance over time; velocity is speed plus direction</h3>
Explanation:
Speed is defined as the change in distance covered by a body with respect to time while velocity the change in displacement of a body with respect to time. Speed is a scalar quantity since it does not specifies direction while velocity is a vector quantity because it specifies both magnitude and direction.
Speed can only be equal to the velocity if it also specifies direction.
Based on the definition above, it can be concluded that speed is the change in distance over time and velocity is speed plus direction.
Answer: I’m not sure but the time and distance will be increasing while they required the distance time so my answer is ((A))
