Starting at x = -13 m at time t = 0 s, an object takes 18 s to travel 51 m in the +x direction at a constant velocity. on a sheet of paper, make a position vs. time graph of the object's motion. what is its velocity?

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

An electromagnet is a device in which moving electric chargers in a coil of wire create a magnet.whats one advantage of using electromagnetic in devices
