Explanation:
the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
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: A.
Explanation: I’m pretty sure that’s it, but I’m not 100% sure. But that’s the best option.
