what is the wavelength of the radio waves transmitted by an FM station at 900 MHz?where 1 M =10^6 and speed of the radio wave is 3*10^8 m/s.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

How does an observation about an object differ from an inference about that object

What is the freezing point of radiator fluid that is 50% antifreeze by mass? kf for water is 1.86 ∘c/m.
