How does a television signal differ from a standard radio wave

Answers

Answer 1

Answer: Signal of television as radio waves are of same origin: electromagnetic waves
The difference between them is only in the frequency in which they are issued.

Answer 2

Answer: A TV signal carries a lot more information that a standard radio signal does ...
it has to give the receiver enough information to draw a picture and color it,
in addition to just making sound.

In order to carry more information, the TV signal has to spread over wider band
of frequency, or a wider 'channel' that a radio signal occupies.
Example: The AM radio band, between 550 and 1700 on your dial, accommodates
many radio stations in a band of roughly 1.2 MHz. And the FM radio band, between
88 and 108 on your dial, accommodates many FM stations in a band of 20 MHz.
But each and every TV channel is given a space of 6 MHz to operate in.

Partly related to this reasoning is the fact that all broadcast TV operation takes place
at frequencies higher than any commercial AM radio, and most TV is at frequencies
that are also higher than all FM radio.

Which of these is the most likely impact of solar prominence on Earth? A) rerouting of aircraft
B) increase in severity of hurricanes
C) long-term electrical power generation
D) improvement in satellite communication

Answers

Solar prominences themselves are of no concern because they are visible in the Hydrogen Alpha wavelength. They are anchored in place by magnetic fields. When these fields break or reconnect, it can send the plasma that makes up the prominence away from the sun. If one of these clouds impacts Earth, they are called CMEs or coronal mass ejections. Depending on the magnetic orientation of the cloud with respect to Earth's the CME can break down our magnetic field resulting in geomagnetic storms, aurorae, power grid fluctuations, and particle radiation near the poles, satellite single upset events, and radio blackouts.

Thus, letter a is the answer.

Answer:

A) rerouting of aircraft

Which term refers to the time interval between the passage of successive wave crests? a. wave height
b. wave period
c. wave speed
d. wavelength

Answers

I believe the correct answer from the choices listed above is option B. The term that refers to the time interval between the passage of successive wave crests would be wave period. It is the time for a particle on a medium to make one complete vibrational cycle.

What force is required to accelerate a body with a mass of 15 kilograms at a rate of 8 m/s²?

Answers

The equation for force is force is equal to mass times acceleration or F = ma where Force or F is measured in Newtons or N (which is also kilogram-meter per second squared), Mass or m is measured in kilograms or kg, and acceleration is measured in meters per second or m/s2. This leads to an answer in kilogram-meter per second squared or kg- m/s2, So if we multiply a body with a mass of 15 kilograms to a rate of 8 meters per second, we get 120 kilogram-meter per second squared.

it is simple 120 N is the answer

The force of gravity between two objects is directly proportional to which of the following? a. the masses of each object.
b. the velocity of each object.
c. the distance between the objects squared.
d. the mass of one object and the distance between the objects.

Answers

Force of gravity =Gxm1xm2 /r^2G= gravitational constantm1 and m2 are massesr is the distance between masses.So a is the correct option

The force of gravity between two objects is directly proportional to the
product of the two masses, and to the mass of each object individually.
