Answer:
Explanation:
average speed is distance traveled over time
v = (50 + 30(1.5)) / (2 + 1.5) = 27.1428571...
v = 27 km/hr

Friction stole the book's kinetic energy, and turned it into heat energy ... which blew away in the breeze.
Answer:
1) a radio are uses by astronomy
2) 6 bilion waves
3) expert vertified
Explanation:
1) in contrast to an "ordinary" telescope, which receives visible light, a radio telescope "sees" radio waves emitted by radio sources, typically by means of a large parabolic ("dish") antenna, or arrays of them.and Radio telescopes are also the primary means to track space probes, and are used in the SETI project. so must been
radio are almostly
ceiver by astronomy
2) Radio waves have the longest wavelengths in the electromagnetic spectrum.
3)Expert Verified
Radio telescopes are telescopes that are specially designed for observation of long light wavelengths
