Answer:
True
Explanation:
Signals used for transmitting information contain many frequencies. Signal Bandwidth refers to the difference between the highest and lowest frequencies of the continuous band. In other words, a signal bandwidth is a range of frequencies.
B.W. = f₂ - f₁
It is measured in Hertz (Hz or per second).
Thus, the given statement is true.
Answer:
Approximately (assuming that the car is moving on level ground, and that there is no friction to hinder the motion of the car.)
Explanation:
Formula for the kinetic energy, , of an object of travelling at velocity :
.
Let and denote the velocity of this car before and after the acceleration.
Kinetic energy of this car before the acceleration:
.
Kinetic energy of this car after the acceleration:
.
Assume that this car was travelling on level ground. Also assume that there is no friction to hinder the motion of this car. The work of the engine of this car would be equal to the amount of that the car has gained:
.
