Now, we will learn about Velocity Time Graphs . Velocity-Time Graphs: To draw velocity time graphs, we will use the three equations of motion. Case 1: Velocity-time graphs with constant velocity (zero acceleration) When the velocity is constant, the velocity time graph, with Y-axis denoting velocity and X-axis denoting time, will be like: As clear from the graph, the velocity is constant (c) throughout the time interval.
Nikola Tesla first invented the radar because he knew the America needed help in World War I since German U boats sank hundreds of our boats. Sure it could only detect roughly 6feet out, but it was a start.
In 1943, the United States tests an anti-radar system to make the U.S. Navy ships invisible to the enemy. Dr. James Longstreet uses his experiment in the destroyer escort USS Eldridge that disappears from Philadelphia. The sailors David Herdeg and his best friend Jim Parker are projected to 1984, where they meet Allison Hayes.
