Answer:
A magnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. They are hence known as 'electromagnetic' waves.
Answer:
Fulcrum
Explanation:
When you use a spoon to prise a lid from a tin you are using a simple machine called a lever. In fact, levers are the basis of many tools in and around your house and work. The way levers operate is by an effort applied at a point, which moves a load at another point through a balance point called the fulcrum.
The driver speeds up with acceleration <em>a</em> so that
35 m/s = 15 m/s + <em>a</em> (10.0 s)
Solve for <em>a</em> :
20 m/s = <em>a</em> (10.0 s)
<em>a</em> = (20 m/s) / (10.0 s)
<em>a</em> = 2 m/s²
True
From what Ive learned its like how you create your own hypothesis for a science experiment it may not work completely that way but you learn what didnt work and what does work
Acceleration = change in velocity / time
change in velocity = final velocity - initial velocity
because the object is slowing down, the acceleration will be negative.
acceleration = (4-34) / 60
acceleration = -30 / 60
acceleration = -0.5 m/s^2
answer : the train is accelerating at -0.5 m/s^2
