Answer:
T1 = 1/12 x 48 MHz = 4 MHz
Timer’s clock period:
The time delay of one machine cycle is given below. We use this to generate the delay.
T2= 1/ 4000000= 0.25 µ sec
For delay of 10 ms:
1. Firstly divide the desired time delay value (10 ms) by the timer clock period.
N= 1 / 0.25µs
N= 10 ms / 0.25µsec
N=40000
2. Subtract the value of N from the maximum number of counts possible for 16 bit timer i.e. 2^16 = 65536.
M=65536-N
M=65536-40,000
M= 25536

Clock source:
Answer:
Light shone on metal expulses electrons from its surface. This phenomenon is the photoelectric effect, and the electrons are called photoelectrons. Experiments indicate that by increasing light frequency, the kinetic energy of the photoelectrons increases, and by intensifying the light, the current increases
The best and most correct answer among the choices provided by your question is the second option or letter B. It is carried on FM wave by modulating its frequency.
In telecommunications and signal processing, frequency modulation<span> (</span>FM<span>) is the encoding of information in a carrier wave by varying the instantaneous </span>frequency<span> of the wave.

Answer:
Explanation:
This question seek to test the difference between a scalar and a vector quantity. A scalar quantity is a quantity that has just magnitude but no direction while a vector quantity is a quantity that has both magnitude and direction. Example of a scalar quantity is speed while example of a vector quantity is velocity.
Hence, it can be that <u>speed has magnitude but no direction while velocity has both magnitude and direction</u>.
They both have the same formula which can be written as
speed = distance ÷ time
OR as
velocity = distance ÷ time
By definition we have to:
The electric current is the flow of electric charge due to the movement (usually of electrons) that a material travels.
Some properties are:
1) Electric conduction: The conductive materials have a large amount of free electrons, therefore, the passage of electricity is possible.
2) The current inside a circuit is directly proportional to the voltage and inversely proportional to the resistance of the circuit. This is what is known as ohm's law:
3) The current can be continuous or alternate.
Alternating current is the electric current in which the magnitude and direction vary cyclically.
The direct current is the flow of electric charges that does not change direction with time.
