Pangea trust me I’ve done this
if it says it has a medium its true
I dont know see the following answers so yeah
Answer:
-0.0314 V
Explanation:
Parameters given:
Initial magnetic field, Bini = 200 mT = 0.2T
Final magnetic field, Bfin = 300mT = 0.3 T
Number of turns, N = 1
Radius, r = 5 cm = 0.05 m
Time, t = 0.025 secs
Induced EMF is given as:
EMF = [-(Bfin - Bini) * N * pi * r²] / t
EMF = [-(0.3 - 0.2) * 1 * 3.142 * 0.05²] / 0.025
EMF = (-0.1 * 3.142 * 0.0025) / 0.025
EMF = -0.0314 V
Answer:
Yes
Explanation:
Non uniform acceleration is any acceleration that is not constant.
If you look at the graphs I have drawn in the above picture, the first two graphs shows a uniform acceleration.
The first graph is a positive acceleration, which means that the object is moving faster and faster at a constant rate. The second graph shows a deceleration, or negative acceleration, which means that the object is moving slower and slower at a constant rate.
For velocity- time graphs, acceleration can be seen by its gradient. So if the slope of the graph doesn't change, it has a uniform acceleration.
Graph 3 shows zero acceleration since the object is moving at a constant velocity (or speed). Thus, the object does not acceleration.
Graphs 4-7 shows a non uniform acceleration.
In graph 4, the object has a decreasing acceleration since the gradient of the graph is decreasing. This can be seen by the slope getting gentler and gentler.
Graph 5 shows an increasing deceleration, since the graph is getting steeper and steeper and the velocity is decreasing with time.
Graph 6: increasing acceleration
Graph 7: decreasing deceleration
