Answer:
Explanation:
To have a deeper understanding of this. Let's begin with the acceleration due to gravity (g), with N pointing downward.
Since magnetic field lines originate in the north, field strength decreases for the upper disk and increases for the lower disk when the disk is in the center of two disks.
According to Lenz's theorem, current-induced would be so that the magnetic field due to this induced current opposes the magnetic field due to which there is an induced current, so induced current will be clockwise for the upper disk and anticlockwise for the lower disk.
If the south pole is pointing backward, the generated current will flow anticlockwise for the upper disk and clockwise for the lower disk.
Answer:
Mass, m = 16.02kg
Explanation:
Given the following data;
Force, F = 157N
Since it's a free fall, acceleration, a = g = 9.8m/s² (acceleration due to gravity).
To find the mass;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
- F represents force measured in Newton.
- m represents the mass of an object measured in kilograms.
- a represents acceleration measured in meter per seconds square.
<em>Making mass (m) the subject of formula, we have;</em>
<em>Substituting into the equation;</em>

Mass, m = 16.02kg
<em>Therefore, the mass of the rock is 16.02kg.</em>
Wavelength = (wave speed) / (frequency)
= (1,450 m/s) / (230 / sec)
= 6.30 meters (rounded)
Hope this helped friend! :)
