Newton has 3 Laws specifically The Three Laws of Motion
Answer:
divide
Explanation:
whenever looking for velocity.just devide
Answer:
42.5W
Explanation:
To solve this problem we must go back to the calculations of a weighted average based on the time elapsed thus,
We need to calculate the average power dissipated by the 800\Omega resistor.
Our values are given by:
Aplying the values to the equation we have:
The correct answer is C. Velocity is a vector and requires a direction.
Explanation:
In physics both speed and velocity are used to study the motion of a body; however, they are slightly different. In the case of speed, this describes the rate of change in position based on distance and time, because of this, speed is based on a magnitude or quantity. On the other hand, velocity is a vector because it does not only includes a change of position but the direction of motion usually based on a specific location reference.
Considering this, it can be concluded the difference between speed and velocity is that "velocity is a vector and requires a direction" because velocity includes both the distance and time (speed) along with the direction while speed focuses only on time and distance.
