Answer:
A signal is produced.
Radio waves are modulated and amplified.
Radio waves are amplified and demodulated.
A signal is seen, heard, or used.
Explanation:
Communication is the method of transmitting information between two or more participants. A radio communication network is a set of static and wireless radio equipment developed to facilitate an entity by enabling particular modes of communication such as one-to-many and one-to-one communication. Radio waves are being used to transmit information spatially from the sender to receiver, by modulating the radio signal in the transmitter. The above steps explains the loop of the radio communication system.
Answer:
A signal is produced- 1
A signal is seen, heard, or used- 4
Radio waves are modulated and amplified- 2
Radio waves are amplified and demodulated- 3

B. pulley

D. inclined plane
The inclined plane is the best simple machine to assist with moving heavy objects into a truck. It allows for less force to be used by distributing the required force over a longer distance.
The simple machine that is best suited to assist with the task of moving heavy objects into a moving truck 1.5 meters above the ground is the inclined plane (option D).
An inclined plane is a flat surface that is inclined or sloped, which allows us to move objects up or down with less force. By using an inclined plane such as a ramp, we can reduce the amount of force needed to lift the heavy objects into the truck.
For example, instead of trying to lift a heavy object straight up into the truck, which would require a significant amount of force, we can use an inclined plane to gradually raise the object by pushing it up the inclined surface. This allows us to distribute the required force over a longer distance, making it easier to move the object.

a. v, = 630m/s,
c. v, - 1630m/s,
T = 2.78 x 10 s
T=5.78 x 10s
b. V = 1820m/s,
d. V, - 1260m/s,
T = 6.78 x 106 s
T=5.78 x 10's
Please select the best answer from the choices provid
Answer:
v = 1630 m/s
T = 5.78 x 10^5 s
Explanation:
The tangential speed of the satellite can be found by requiring that the gravitational force on the satellite is equal to the centripetal force:
where
G is the gravitational constant
M=5.97 x 1024kg is the Earth's mass
m is the satellite's mass
is the Earth's radius
is the altitude of the satellite
v is the speed of the satellite
Solving for v,
And the period of the orbit is equal to the ratio between the distance covered during one revolution (the circumference of the orbit) and the speed:
So the correct answer is
v = 1630 m/s
T = 5.78 x 10^5 s

Explanation:
speed of 5,000 meters per second?
Answer:
Period T = 0.1 second
Explanation:
Given that the
wavelength = 500 meters
speed V = 5000 meters per second
The wave speed is the ratio of wavelength to period of the wave. That is,
V = λ/T
Where
V = wave speed (m/s)
λ = wavelength (m).
T = period (s)
Using the formula above gives
5000 = 500/T
Make T the subject of formula
T = 500/5000
T = 0.1 s
