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.
Explanation:
A molecule can be made up from same or different elements. Whereas a compound will have different atoms.
Therefore, the difference between a molecule and a compound is that a compound is made up of atoms from different elements.
For example, 
is a molecule and NaCl is a compound.
And a chemical change creates a new substance.
A wagon is pulled at an angle of 30 degrees to the horizontal.
The answer depends heavily on what 'objects' you're talking about.
