What is the density of the baseball? g/cm3
The acceptable density range of official baseballs is
between 0.70 g/cm and 0.80 g/cm? Is the
questionable ball in this range of acceptable density?

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.

Ionic compounds can be readily dissolved in water because the high dielectric constant of water screens and decreases the force between the oppositely charged ions.

If frequency goes down, what happens to wavelength? does it get shorter or longer?
