Answer:
Explanation:
It is given that,
Number of turns in the coil, N = 220
Diameter of the coil, d = 4.4 cm
Radius of the coil, r = 2.2 cm = 0.022 m
Magnetic field produced by the poles of magnet, ![B=96\ mT=96\times 10^{-3}\ T](https://tex.z-dn.net/?f=B%3D96%5C%20mT%3D96%5Ctimes%2010%5E%7B-3%7D%5C%20T)
Current flowing in the coil, I = 15 A
Let M is the coil's magnetic dipole moment. Its formula is given by :
![M=N\times I\times A](https://tex.z-dn.net/?f=M%3DN%5Ctimes%20I%5Ctimes%20A)
![M=220\times 15\times \pi (0.022)^2](https://tex.z-dn.net/?f=M%3D220%5Ctimes%2015%5Ctimes%20%5Cpi%20%280.022%29%5E2)
![M = 5.01\ A.m^2](https://tex.z-dn.net/?f=M%20%3D%205.01%5C%20A.m%5E2)
So, the coil's magnetic dipole moment is
. Hence, this is the required solution.
Answer:
3.75 m/s
Explanation:
From the question given above, the following data were obtained:
Acceleration (a) = 1.5 m/s²
Initial velocity (u) = 0 m/s
Time (t) = 2.5 s
Final velocity (v) =?
a = (v – u) / t
1.5 = (v – 0) / 2.5
1.5 = v / 2.5
Cross multiply
v = 1.5 × 2.5
v = 3.75 m/s
Hence, the escape velocity of the squirrel is 3.75 m/s
S~ cientists publish their original research in scientific journals, which are fundamentally different from news magazines. The articles in scientific journals are not written by journalists – they are written by scientists. Scientific articles are not sensational stories intended to entertain the reader with an amazing discovery, nor are they news stories intended to summarize recent scientific events, nor even records of every successful and unsuccessful research venture. Instead, scientists write articles to describe their findings to the community in a transparent manner.
