Describe how microwaves are used in the transmission of television signals by satellite

Microwaves are able to be transmitted in a tight beam (diffracting less than radio waves) and so are used to transmit television signals to satellites in orbit. Like a mirror, it focuses the waves onto a detector which then sends the signal to a decoder box connected to a television.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
