Answer:
A) ΔV = 1.237 V
B) K.E = 1.237 eV
Explanation:
B)
The initial kinetic energy of the electron is given by the following formula:
where,
K.E = Kinetic Energy of electron = ?
m = mass of elctron = 9.1 x 10⁻³¹ kg
v = speed of electron = 660000 m/s
Therefore,
K.E = 1.98 x 10⁻¹⁹ J
K.E = (1.98 x 10⁻¹⁹ J)()
<u>K.E = 1.237 eV</u>
A)
The energy applied by the potential difference must be equal to the kinetic energy of the electron, in order to stop it:
where,
e = charge on electron = 1.6 x 10⁻¹⁹ C
Therefore,
<u>ΔV = 1.237 V</u>

Answer:
The correct option is D
Junction diodes are preferred over point-contact diodes for most purposes.
Explanation:
Point contact diode:
This type of diode is constructed by touching a metallic wire with an N-type semiconductor to form a small area of contact, hence the name point contact diode. The switching speed of these diodes is better than a conventional diodes.
These diodes are not usually preferred due to their low current ratings and poor reliability.
P-N junction diode:
This type of diode is constructed by joining two regions of opposite conductivity N-type and P-type material, a PN-junction is formed which allows the current to flow in one direction only. The conversion of AC current to DC is done by this process called rectification.
Answer:
Ok, so...... Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces. In the example below, the net force would be 900 Newtons (450 + 450 = 900), and the object would move to the right.
