We can use the Doppler Effect to study the movements of far away stars and galaxies. True False

How can a physical property such as mass and texture change

A 1500 kg roller coaster train is at rest at the top of a 65 m drop before it begins to travel down the hill. At the bottom of the hill how fast is the train moving?

For slowly moving objects, the drag force in water is approximately proportional to the speed of the object. The Escherichia coli (E. coli) bacterium propels itself slowly through water by means of long, thin structures called flagella.

Consider two submarines A and B traveling through water. Submarine A is moving at 5.00 m/s. Submarine B is moving at 8.00 m/s while emitting a sonar wave at a frequency of 1.20 * 103 Hz. The speed of sound in water is 1.
