The answer is axial precession. Axial precession refers to
the very slow motion of the Earth’s axis, which almost requires twenty-six
thousand (26,000) years to complete a full rotation. This Axial Precession is
caused by the effects of gravitational pull from the Sun and the Moon towards
the Earth.
Answer:
The kinetic energy is
Explanation:
From the question we are told that
The potential difference is
The potential energy of the end is mathematically represented as
q is the charge on an electron with a constant value of
substituting values
Now from the law of energy conservation
The
Where is the potential energy at the end
So
The negative sign is not includes because kinetic energy can not be negative
The distance should be 4m from the wire in order to get the magnetic field of 0.100μ .
- The magnitude and direction of the magnetic field due to a straight wire carrying current can be calculated using the previously mentioned Biot-Savart law. Let "I" be the current flowing in a straight line and "r" be the distance. Then the magnetic field produced by the wire at that particular point is given by ...(1)
- Since the wire is assumed to be very long, the magnitude of the magnetic field depends on the distance of the point from the wire rather than the position along the wire.
It is given that magnetic field 40.0 cm away from a straight wire is 1.00μT having current 2.00 A .
From equation (1) magnetic field 40.0 cm = 0.4m away from a straight wire is 1.00μT which is given by .....(2)
From equation (1) magnetic field 'r' m away from a straight wire is 0.100μT which is given by ...(3)
On dividing equation (2) by (3) , we get

Answer:
3.0 would be it
Explanation:
Because if you think bout it the 5.0 negative 2.0 is 3.0
Answer:
At supersonic speeds (those greater than the local sound speed), there is no sound heard as an object approaches an observer because the object is traveling faster than the sound it produces. Only after the object has passed will the observer be able to hear the sound waves emitted from the object.
