The Arecibo radio telescope in Puerto Rico is observing the radio spectrum of a distant star. It observes an anomaly at a frequency of 490 MHz. What wavelength of
light does this correspond to in base SI units?

What is the rate of change in a objects position?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.

Which type of reaction is shown in this energy diagram ?
