What are three types of electromagnetic waves that are used to transmit information? What types of devices are used to receive each type of wave? Type of electromagnetic wave:

Receiver devices:

Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. how long will the ball be in the air before it lands? how far will the football travel before it lands?

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m^2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute?

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
