Answer:
The operating system
Explanation:
The job of the operating system is to manage system resources allowing the abstraction of the hardware, providing a simple user interface for the user. The operating system is also responsible for handling application's access to system resources.
For this purpose, the operating system allows a user to run applications on their computing device.
Cheers.
Answer:
The direction of the magnetic field around the coil reverses. The force on the cone now pulls it back in. Repeatedly alternating the current direction makes the cone vibrate in and out. The cone vibrations cause pressure variations in the air, which are sound waves.
Explanation:So as it goes back and forth it makes a sound from the vibration.
Answer:
Using Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common-carrier frequency.
Explanation:
- In SSB modulators, we pre-process a real signal by Hilbert Transform filter to form another real signal
- The signal has the same spectral amplitude but has 90° phase shift at each frequency relative to its input signal.
- The ordered pair gets almost all of its negative components cancelled
- thus, with the use of Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common carrier frequency.
Answer:
Mass of earth will be 
Explanation:
We have given acceleration due to gravity 
Radius of earth = 6370 km =
Gravitational constant 
We know that acceleration due to gravity is given by
, here G is gravitational constant, M is mass of earth and R is radius of earth
So 
So mass of earth will be
