The final speed of a lion running 30 m/s accelerates at a rate of 3 m/s3 for 5 seconds it’s 3.2
<span>The gravity of earth depends on the magnetism from its core. as this magnetism increases, the magnitude of the gravity increases.</span>
To solve this problem it is necessary to apply the concepts related to the magnetic flow of a coil and take into account the angles for each case.
It is also necessary to delve into part C, the concept of electromotive force (emf) which is defined as the variation of the magnetic flux as a function of time.
By definition the magnetic flux is determined as:
Where
N = Number of loops We will calculate the value for each of the spins
B = Magnetic Field
A = Cross-sectional Area
Angle between the perpendicular cross-sectional area and the magnetic field.
PART A) The magnetic flux through the coil after it is rotated is as follows:
PART B) For the second case the angle formed is perpendicular therefore:
PART C) The average induced emf of the coil is as follows:
