Answer:
Step-by-step explanation:
2/c
3/both magnitude and direction are needed to define it.
4/Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
5/There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
6/The rate at which velocity changes with time is called Acceleration is a measure of how quickly the velocity is changing.
7/The instantaneous speed of an object is then the magnitude of its instantaneous velocity. Speed tells you how fast. Velocity tells you how fast and in what direction.
Your answer will be: 3.30549069 x 10x10x10x10x10x10x10x10x10x10x10x10x10
You should multiply eat side by 9 to break down the fraction so you can then get rid of the -7. Therefore you are moving everything to the other side
