Answer:
The wave function for a material particle is often called a matter wave. The relationship between momentum and wavelength for matter waves is given by p = h/λ, and the relationship energy and frequency is E = hf.
Explanation:
In the left-hand rule, the field is represented by the forefinger and it is perpendicular to the motion.
<h3>Fleming’s Left-Hand Rule:</h3>
A force perpendicular to the field's direction and the direction of the current flow is experienced by a current-carrying conductor when it is exposed to an external magnetic field. According to Fleming's Left Hand Rule, if the thumb, forefinger, and middle finger are arranged in a straight line on the left hand, the thumb will point in the direction of the force experienced by the conductor, and the forefinger will point in the direction of the magnetic field, and the middle finger will point in the direction of the electric current. This rule is employed to determine the magnetic force's direction within an electric motor.
Fleming’s Left-Hand Rule are essential rules applicable in magnetism and electromagnetism. They were created by John Ambrose Fleming in the late 19th century as an easy method of determining the direction of motion in an electric motor.

Answer:
Part a)
Final speed of the corn is 19.05 m/s
Part b)
Kinetic energy of the corn is 3.1 J
Explanation:
Part a)
As we know that the initial position of the corn is
h = 18.5 m
now we also know that it will fall from rest and moving under constant acceleration so we will have
Part b)
Kinetic energy of the corn is given as
Answer:
Explanation:
Force on a current carrying conductor in a magnetic field is given by the following expression
F = B i L where B is magnetic field perpendicular to wire or current , i is current and L is length of the wire.
Magnetic field of 1.5 x 10⁻⁵ T is making an angle of 60 degree with the wire so the component of field perpendicular to it
B = 1.5 X 10⁻⁵ Cos 30° = 1.3 x 10⁻⁵ T.
Force = BiL
= 1.3 X 10⁻⁵ X .4 X 1
= 5.2 X 10⁻⁶ N.
The direction of force can be found out from Fleming's left hand rule . It will be along downward direction.
