<span> An electromagnet is a current-induced magnet. The basic setup is an electrical current circulating around some magnetizable material, such as an iron rod. The current and number of times the current circulates around determine the magnetic strength. Therefore, the same things that strengthen a current are the same things that strengthen an electromagnet.
</span><span> As current runs through a straight wire, a circular magnetic field is generated around it. When a wire is made into a circle, the current generates a magnetic field parallel to its axis. If you pile loops on top of each other, as in a coil or solenoid, you increase the magnetic field strength.</span>
Its a waste of time, you have to not only write it down, but study it after too . other than that notes are great.
Answer:
k = 1/18
Explanation:
Data:
a = -k
to = 0s Vo = 12m/s
t = 6s the particle chage it's moviment, so v = 0 m/s
We know that acceleration is the derivative of velocity related to time:
rearranging...
Then, we must integrate both sides:
V = 0 because the exercise says that the car change it's direction:
k = 1/6
In order to find X - Xo we must integer v*dT = dX
so...
integrating...
X - Xo = 54m
Answer: Speed
Explanation:
Speed is Defined as defined as D/T or distance over time
Chattanooga - Chatype, London - Johnston, Berlin - BMF Change, Milan - Milano City, Eindhoven - Eindhoven, Stockholm - Stockholm Type, Minneapolis, and St. Paul - Twin.
