A wave is traveling at a constant speed. The frequency is 2 Hertz, and the wavelength is 1 meter. How would the wave properties change if the wavelength decreased from 1 to 0.5 while the speed stayed the same? The amplitude would double.
The amplitude would decrease by one half.
The frequency would double.
The frequency would decrease by one half.

"acknowledging a right to benefit from the presence of animals requires government action to ensure human access to animals in a number of different spheres," writes jessica pierce, ph.d., in psychology today. the pragmatic meaning of the term "right" in this statement is

In the family tree below, people with the recessive trait of attached earlobes are shaded gray.

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?
